Interpreting the carbon isotope ratio signal of terrestrial photosynthesis
The IZOECOCARB project has the goal to resolve some scientific uncertains especially about sources and sinks of the carbon dioxide, the most important greenhouse gases.This gas is the major cause of changes in atmospheric composition that may force climate change.The IZOECOCARB project provides scientific information critical to reducing uncertainties on the carbon dioxide at the local and regional level in some selected sites in Romania. The research is focused on the study of the role of the respiration of the ecosystems as source of carbon dioxide with help of the . The knowledge of this dynamic helps us to account for sources and sinks of CO2 at the selected sites. Respired carbon dioxide from canopies and soils is mixed by turbulent motion in air spaces within a canopy. This ecosystem-respired carbon dioxide increases the atmospheric carbon concentration. We sample air within the canopy and analyze the carbon dioxide for both concentration and isotope ratio and create a „Keeling" plot as shown in the figure below (Pataki, Global Biogec. Cycles, 17, 1022-1029, 2003).
Photosynthesis discriminates against 13CO2 resulting in organic matter (δ 13Cp) that is depleted to the atmosphere. For C3 plants the overall relation is given by Farquhar (Annual Rev. Plant Physiol. Plant Molec. Biology, 40, 503-537, 1989)
Δ = a + (b-a)(ci/ca)
where ca and ci are the atmospheric and intercellular partial pressures of CO2, respectively a=4.4 ‰ (diffusional fractionation against 13CO2), and b=27 ‰ (net fractionation during carboxylation). Discrimination during photosynthesis has been viewed at three scales: leaf, canopy and ecosystem. While the Δ describes carbon isotope discrimination at the leaf level, Δcanopy is integrated photosynthetic discrimination of all leaves within the canopy. The carbon isotope ratio of ecosystem respiration is not a constant. The carbon isotope ratio of CO2 respired from ecosystems (δ 13CR) could be measured based on changes in the concentration CO2 air and isotope ratio of atmospheric CO2 (δ 13Cair) within the footprint of interest. By ploting the mixing relationship between δ 13Cair and 1/ CO2 air of atmospheric CO2, a linear relationship was obtained and the intercept of this relationship was the isotope ratio of the respired CO2 input in the canopy air space.

The most important result of this project in 2005 was the case studies for the respiration of some particular ecosystems as source of atmospheric carbon.
The 6 ecosystems were selected for studying: 3 forests, 1 pasture, 1 agricultural area and 1 wet area. The main source of the atmospheric CO2 was found to be the respiration of these ecosystems. These sources were described using stable isotopes. The Keeling plots (δ 13C vs. 1/[CO2]) were constructed and the δ 13CR (relative variation of 13C in plant respiration) for each ecosystem was found. The δ 13CR are different because the type of vegetation is different for the studied ecosystems. These values vary with environmental parameters (temperature, precipitation) and also there is a diurnal and seasonally variation. This study is important because it helps to partition and quantify the sinks and the sources of atmospheric carbon. The atmospheric observations were used to check patterns of some particular terrestrial isotopic discrimination that have been derived using eco-physological models. These models are all based on the models of photosynthetic fractionation developed by Farquhar.

Isotopic methods for the control of wines
The measurement of various isotopic ratios 2H/1H, 18O/16O, 13C/12C, 15N/14 N in different fractions of a product often enables the characterization of the origin of starting materials. Isotopic methods have shown to be a major tool for checking the compliance of food product with national and regional regulation.
The main result of the IZOVIN project was the methods for analyzing of 13C and 18O in wine. The 13C from wine was determined on carbon dioxide resulting from the combustion of the ethanol from wine. The carbon dioxide resulted by combustion was cryogenic purified as it is shown in the below figure. The ethanol from wine was extracted by distillation with a special column.
The 13C content in ethanol was measured by mass spectrometry technique and the results were reported to PDB reference. The method for determination of 18O in water fraction is based on the isotopic equilibration of the water with a CO2 gas. After equilibration, the 18O content was measured with mass spectrometer against that of the reference V-SMOW and is expressed on the relative scale δ 18O. The precision of the measurement was ± 0.1 ‰. The 13C content in wine is used to detect the chaptalisation with cane sugar of the wine. Also, the 13C is used for the characterization of the natural gasification of sparkling wines, and for the characterization of geographical origin of wines. The 18O is used for the detection of addition of water and for the characterization of the origin of wines.

The study of the use of isotopic methods for investigating the mineral waters
The main objective of the PIMEGA project is scientific administration of mineral water resources from the area of the Oriental Carpathians, using stable and radioactive isotope techniques and GC-MS technique.
In the area of Oriental Carpathians there is a high concentration of mineral water resources. They come from underground waters containing especially bicarbonates, sulfates, and chlorides of alkali and alkaline-earth metals. We made a study that will help us to solves the following problems correlated with the main objective:
- The estimation of the mixing degree with other types of water
- Pointing the location and proportion of the recharge
- Calculation of the flow speed of underground waters
- Elaboration of a hydrologic concept called underground water system
- Performing isotopic ratio measurements on environmental isotopes in order to establish the isotopic stamp and the origin of the waters
- Identifying the mineral water spring types by measurements of natural concentrations of tritium and 14C
- Identifying of traces of pollutants by measurements of isotopic ratio 15N/14N and 34S/32S
- Corroborating these last measurements with trace analyses by GC-MS.
This study has shown that we can use the data obtained from isotopic analyses for the elaboration of an underground water system (by computer modeling). Also it was elaborated a strategy for the management of the mineral waters from the Oriental Carpathians area, and for the determinate of the effects of mineral waters exploiting by measuring their salinity degree. It was shown how we could made a data base for the mineral water springs from the Oriental Carpathians
In the PIMEGA project we apply isotopic methods in hydrological investigations of some mineral water springs from the Oriental Carpathians area. Using measurement techniques based on stable isotopes abundance determination of H, O, C, N and S and of radioactive isotopes T and 14C, the origin, age and mineral water spring type can be determined. Usually, the isotopic analyses take into account only a few elements naturally present in the hydro-geological systems, which generates the so called "environment isotopes": H, C, N, O and S. The environment isotopes are useful for the origin elucidation and the age of the underground water determination, as well as for the investigation of the aquifer supply processes, mixing of different waters, geochemical reactions, chemical kinetics, water - rock - atmosphere interaction and polluting processes.
The stable isotopes the most often used are: deuterium - 2H, oxygen 18 - 18O, carbon 13 - 13C, sulphur 34 - 34S, nitrogen 15 - 15N, and the radioactive isotopes: tritium - 3H and carbon 14 - 14C. The most important mechanisms controlling the concentration variability of the two-isotope category are fractionation for the stable isotopes, respectively the disintegration in the case of the radioactive ones. The figure shows the change in isotopic composition of oxygen and deuterium of meteoric waters during recharge and groundwater formation (Gat, J. Hydrol., 7, 334, 1969)

Studies of seawaters intrusion on aquatic ecosystems of the Danube Delta Biosphere Reserve
The seawater-deltaic water interaction occurs in three well-defined physical spaces: 1) in the lacustrine ecosystems, 2) on channels and 3) in aquifer situated near the coastal line of Black Sea.
The study of intrusion of seawater in aquatic ecosystems of deltas is important due to the necessity to understand the causes that lead to the modification of the physical, chemical and biological parameters with the impacts on major disequilibria of the ecosystems in coastal areas with preserve regime or large development of the tourism and large needs of potable water supply. Coastal ecosystems are sensitive to the salinity and nutrient concentrations of coastal waters. The conservative deltaic water management constitutes the most effective means of minimizing saltwater intrusion in delta. The primary objective of this effort is to develop an in-depth understanding of the Danube Delta water system with emphasis on saltwater intrusion in the Rosu Lake area, between the Sulina Branch and Sf. George Branch. The project will incorporate new data in hydrologic modeling techniques that have not been applied to the Danube Delta. Chemical concentration (anions, cations and hypothetic salts), natural isotopic contents (stable isotopes of water, tritium) and hydrobiological (phytoplankton, zoo-plankton and zoo-benthos) parameters of the fresh water of delta are the primary types of data employed to characterize the bi-dimensional hydrologic system in Danube Delta, focusing on deuterium content as a tracer of the seawater intrusion.
The objectives of this project are to analyze the natural abundances of the hydrogen isotopes in correlation with the chemical, hydrobiological and physical parameters from deltaic water samples. The analyze the scale, the history data, the specifics procedures for the evaluation of the lacustrine zone from coastal area of Danube Delta, the analyze of the range and the critical values of the system transformations, of the spatial and temporal distribution (systematic, cyclic, random variations) of the values measured, of the key processes that define the interaction and the feed-beck in Rosu Lake area (transport, dispersion, stratifications, influx of water, evapotranspiration) and the elaboration of the heuristic model and isotopic model for the water dynamic in Rosu Lake area. The systematic and consistent measurements of all indicators were analyzed by deductive, inductive and correlative means, using the computational methods.
The most important preliminary results in 2005 are the following:
- The finalization of Bastroe channel (on the Chilia branch) induced the increasing of water flow on Chilia branch and the decreasing of water flow on Sulina and Sf. Gheorghe branches;
- The are areas for still water in the north and the south of Sulina branch;
- The nitrogen and phosphorus contents are higher than the admissible limits;
- The climatic changes from upper Danube are reflected in isotopic concentration of Danube's' water.

The study of translocation and accumulation of hydrogen isotopes in the plants
The target of present project is to obtain advance scientific information, which cannot be provided by classical study method, concerning the coupling of the physical (isotopic fractionation), chemical (biosynthesis) and biological (photosynthesis, respiration) processes from plants. The research will be focused on the development of knowledge and methods capable to measurement the isotopic fractionation that occurs during the transport of water in plants and to establish the implications and the role of these measurements for the scientific knowledge and the development of practical applications. This scientific information will be obtained by the development of the natural isotope tracers techniques as the investigated tool, by the integration and corroboration of all information that are able to be obtained using the high, stable isotope of hydrogen (2H or D) plants with short vegetation time. The isotopic response of water at climate global changes is very sensible and prompt, therefore is expected that the plants to respond at these changes into the hydrogen natural abundances from inorganic and organic matter from plants. The isotopic fractionation in plants would be attributed to synergic effects of isotopic fractionation during photosynthesis, organic matter biosynthesis and transpiration with the isotopic signal from precipitation and atmospheric moisture, via sol. Two ways of study was approached: the one is the theoretical approach to develop the scientific base of the investigation methodology (evapotranspiration from plant leafs) and the another is to develop the research analytical method needed for measurements from plants experimental fields. The measurements help to elaborate a conceptual model for isotope incorporation in plants and to obtain the scientific base for the methodology of large-scale applications of natural isotopic abundances from plants at the climate and agronomic practice reconstruction, water use efficient, food security, genotypes crops that efficiently use water and are resistant to climate global changes stress
The study is destined to exclaim the following:
- The isotopic concentration from plant water can they be theoretical predict?
- How the isotopic signal from water responds to the environmental stress?
- The deuterium-depleted water is the modulator for the plant resistance at the ultraviolet light stress?
- The conversion of chlorophyll a to chlorophyll b does depend to the isotopic deuterium content, and if the response is yes what is the consequence?
- The water use efficient can be point out by isotope content of water?
- The vegetables geographical provenance can be point out by the natural isotopic tracers techniques?
The objectives are to analyze the natural of hydrogen from isotopic point of view (the identification of isotopic range in water, the pathways of water movement, the coupling of the physical and bio-chemical processes, causes and isotopic fractionation effects, the quantifying of the isotopic fractionation factors, all information being the support for theoretical and experimental approach), the development of the methodologies of sampling, storage and preparation for isotopic measurements, the obtaining of the experimental data (isotopic, chemical, biological) for plants (lettuce and tomato) growth in controlled, different conditions, the correlative analyze of experimental data, the evaluation of the plants isotopic response to the environmental factors changes, the development of the mathematical formalism for the theoretical models of evapotranspiration, the verifying the hypothesis concerning to the deuterium content in plants and the elaboration of models for the isotopic incorporation in plants.
The most important results in 2005:
- The analyses of deuterium concentration from time series of time a deuterium content (1975-2005) from precipitation fallen on Cluj-Napoca.
- Isotopic method of water's infiltration in soil and of the determination of infiltration water ratio in soil.
- The analyses of deuterium incorporation in the components of the system atmosphere-soil-plants.
- Take up of the water from soil in plants occurs with isotopic fractionation.
- The magnitude of the isotopic fractionation factors in plants depends by endogen and exogenous conditions of plants growth.
- The efficiency of water use can be controlled by isotopes tracers.
The ratio of chlorophyll a / chlorophyll b is influenced by deuterium content from watering.

The determination of the levels and fates of organic pollutants by chromatography and mass spectrometry on environmental matrices
Water samples collected from the river "Somesul Mic" downstream the Town of Cluj-Napoca were investyigated. The samples were stored for 48 hours at 6o C and pH=2. Then the samples were submitted to the extraction procedure. The Solid Phase Extraction (SPE) method was used. For each sample a 250 ml volume was employed. The cartidges were conditioned with suited solvents at HPLC purity level. The extract of organic compounds obtained in this way, was concentrated with the aid of a flux of dryed nitrogen at room temperature, then submitted to the chromatographic and mass spectrometric analysis. Diphenylamine was used as internal standard.
The GC-MS coupling FISONS 800MD was utilized to investigate the samples. The mass spectra were obtained in the following conditions: electron impact ionization, ionizing electron energy 70 eV, source temperature 175oC. Chromatographic separation was obtained in a programmed temperature regime in the interval 90 - 320oC with variable slope in order to separate a palette as broad as possible of compounds (from the point of view of their molecular weight, polarity and volatility).
Experimental data were obtained by continuous acquisition of mass spectra at a rate of one mass spectrum per second. The subsequent signal processing allows data presentation in several ways:
- Independent mass spectra in the mass range 40 - 800 Dalton,
- Total current chromatograms (TIC) obtained by summing all the detected ions while the mass spectrum is acquired, versus elution time
- Selected ion chromatograms (fragmentograms) obtained by the representation of the signal corresponding to an ion of selected mass versus time
The aim of the study was to investigate classes of organic compounds present in semnificative amount in surface water and to determine molecular marker compounds. Several steps were followed:
- The detection and the quntitation of compounds belonging to different classes
- The development of analytical methods for the detection of specific markers
- The discrimination between different pollution sources
- The identification of pollution sources
Taking into account the pollution specificity in the areal studied, two sorts of samples were investigated: water samples and sediment samples. The pollutant compounds identified in water are marked with the symbol (*) and those from the sediment with (#)
The following compound classes were identified:
- -Sterols, markers for untreated waste water (*, #);
- -Plastifiers : Phtalates markers for the pollution of industrial orrigin (*,#);
- -Fatty acids, markers for the pollution of domestic orrigin (*);
- -Pharmaceutic products medecine residues unmetabolized (*, #);
- -Alimentary anti-oxidants, markers of the alimentary residues (*,#);
- -Normal alkanes (#);
- -Policyclic Aromatic Hydrocarbons (PAHs)(#);
- -Dibenzothiophens (DBTs)(#);

High sensitivity detector for explosives
The functional model of the ultrahigh sensitivity explosive detector, based on an original time- of- flight mass analyzer was tested.
The basic performances of the detector were measured. Ion currents of 2.6 nA were obtained at the ion source level. The ion current reflected by the cylindrical electrostatic mirror for the assembly working in a continous regime was around 6*10-11A. The final test of the functional model allowed the optimization of the performances of the instrument. Among others, an ion current of 11nA was obtained, next to the ion source, the sensitivity being around 10-4 A/Torr. The useful, collimated ion beam attained the level of 3nA. The ion curent resulting from the integration of the ion packets, pulsed with a frequency of 500Hz, attained 4*10-14 A.
During the final testing of the detector, operated in a simplified configuration, mass spectra of various explosive substances or mixtures were obtained. The mass scale was checked by the 28 u mass peak from the residual gas, at 22.5 µs after the trigger signal. For the main peak of the methane the sensitivity was 5.6*103 V/torr while for that of nitrobenzene it was very close to the above value.

Ultrasensitive monitoring of pollutants based on tandem systems using nonconventional detectors
Pollution became a subject of major concern at a global scale. We mean here:
- Inorganic gaseous pollutants, basically those resulted from industrial and combustion processes but also those from natural sources (SO2, NO, NO2, HF). With air moisture these compounds generate corrosive acids, while with solar radiation they contribute to ozone formation, which in turn is extremely reactive and toxic.
- Volatile organic compounds (VOC). Some of them participate to photochemical reactions and contribute to development of soil-level ozone; other VOCs participate to destruction of stratospheric ozone. Many of the VOCs are toxic and/or carcinogen.
- Persistent organic pollutants (POP). These are organic compounds with a very high level of toxicity, persistent in the environment; they produce a bioaccumulation effect in fatty tissues of living organisms and present the trend to migrate towards the zones with a cold climate.
The great diversity of pollutant compounds, and also a very low level of concentration at which they shows toxicity, brought to the development of a very sophisticated and complex instrumentation, and to the conception and standardization of analytical methods characterized by high sensitivity and precision.
In this project some non-conventional methods for accurate and ultrasensitive determination of some pollutant substances classes are being proposed, methods based on tandem coupling of chromatographic separators with specific, non-conventional detectors. The element of novelty of the proposed research relies in utilizing some originally designed and produced detectors and in the coupling manner of these detectors with chromatographic-type separators.
The following detectors are to be used in these coupling procedures:
a) High-resolution electrolytic detector - for halogenated derivatives, volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), pesticides, insecticides, and oil products.
b) Thermoconductive detector based on polymeric filaments, for small molecules (inorganic gaseous pollutants SO2, NO, NO2, H2S, CO, CO2), and
c) Detector based on ion mobility, especially for organic toxic substances (POPs: Aldrin, Dieldrin, Endrin, Chlordane, DDT, Heptachlor, Hexachlorobenzene, Mirex, Toxaphene, PCBs, Dioxins and Furans).
It is taken into consideration the automation of the process of data acquisition and processing, and data remote transmission.
Three studies concerning the influence of the physico-chemical processes on the performances of the main detector parameters based on the ion mobility,thermal conductivity and electrolytic cell were elaborated.
The calculus, the design and the modeling of the detectors and its interfaces with gas-chromatographs were performed

Development of a high performance computerized control system dedicated to isotopic separation process control in 15N separation plant
The process of 15N separation by chemical exchange in Nitrox system is automatically maintained in the optimal operation conditions using a computerized control. By automatic control results a maximum production of 15N with a minimum of raw materials and energy consumption.
The isotopic product is sampled and analyzed using a dedicated mass spectrometer. An overall closed loop through the separation plant including this mass spectrometer could be very efficient, but the theoretical analysis is too complex and it is very difficult to realize in practice. Therefore multiple local control loops are preferred to apply for each important and with product strongly correlated parameter. Between these parameters there are complex interdependencies, governed by differential equations.
The complex control tasks are accomplished with a PC computer based system. The PC controls the separation plant through the input/output hardware. The PC is equipped with standard input/output ports, but in order to use it in the complex feedback loops, extra input/output hardware - dedicated input/output module cards - must be added to it. In the figure below is represented the simplified block diagram of the computer controlled 15N separation plant.

Development of fuzzy logic control algorithm for 15N isotopic separation plant
The control problem was solved considering two forms of knowledge:
- objective knowledge, which uses the control engineering problem formulation based on mathematical model of the separation process
- subjective knowledge, which represents linguistic information, very difficult to quantify using classical mathematics - e.g., the rule of HNO3 solution and SO2 flow rates adjustment in order to maintain a proper height and position of chemical reaction zone in the product refluxer
The above mentioned two types of knowledge were coordinated in a logical way using fuzzy logic control system, which has the possibility to handle simultaneously numerical data and linguistic knowledge.
In order to map input data vector into a scalar output, i.e., numbers to numbers a front-end "fuzzifier" and a rear-end "defuzzifier" was added to the usual fuzzy logic model. The inference engine of the control system maps the input fuzzy set into the output one. The inferential procedure handles the way of rules in which they are combined to maintain the isotope separation process in the optimal operation conditions.
In order to assure the conditions for the 15N/14N isotopic exchange in NO, NO2 - HNO3 system on (packed), separation columns, one of the most important task is to maintain the same position of the chemical reaction zone between HNO3 (s) and SO2 (g) on the packing in the product refluxers:
2HNO3 + 3SO2 + 2H2O → 2NO + 3H2SO4
2HNO3 + SO2 → 2NO2 + H2SO4
The flow-rates of the nitric acid solution in the separation columns are maintained using metering pumps. The position of the reaction zone in the product refluxers was maintained at a given optimal height controlling the flow of the sulphur dioxide by means of a fuzzy logic controller.
The first action of the control procedure is the accurate localization of the chemical reaction zone in the product refluxers by sampling the temperature along the refluxer, with seven special temperature sensors. The temperature distribution in the refluxer is computed by spline interpolation.
Cubic spline interpolation is a useful computing technique to interpolate between known sampled points, due to its smooth characteristics.
Unfortunately it does not prevent overshoot at intermediate points, which is essential for many chemical engineering applications. The developed interpolation method prevents overshooting by reducing of smoothness. It combines the smooth curve characteristics of spline interpolation with the non-overshooting behaviour of linear interpolation. That was achieved by eliminating the requirement for equal second order derivatives at every point and replacing it with specified first order derivatives. The position and the maximum value are accurately obtained by computing the first derivative, the developed algorithm being fast enough to run in real time.

Development of an user friendly graphical interface to watch the process in the 15N isotopic separation plant
The computer control of isotopic plant has a great advantage being very flexible in implementing all adequate control software with operator friendly interfacing routines.
In the development of the control software one of the RAD systems is taken under consideration. A Rapid Application Development (RAD) system allows the programmer to produce a stable Windows program (application) relatively quickly and without a detailed knowledge of the inner workings of Windows itself. Common RAD packages include Visual Basic, Visual C++ and Delphi. For this application we use Delphi. Delphi generates fast compiled code without sacrifying the execution speed. In creating with Delphi Win32 console applications or Win32 graphical user interface (GUI) programs we have all the power of a true compiled programming language (Object Pascal)

Our institute is involved in the development of a Romanian Hydrogen Platform, with the major challenges for hydrogen to become a successful energy vector in the future. The research consist in developing of new and efficient technologies in hydrogen production, storage and in the end uses. Technologies considered under this goal include: improving hydrogen production technologies, developing innovative ideas for hydrogen transport and storage, capable to be employed in very practical propose like engine supplies and fuel cell.
INCDTIM develops the hydrogen storage technology. An analysis of the H2 storage solutions was realized, based on metal hydrides.

Search for new physics in ATLAS experiment from LHC using ATLAS-grid software environment
This is a fundamental research in particle physics phenomenology using advanced methods in computing and data analysis. The project is investigating ATLAS discovery potential for new physics beyond the Standard Model of particle physics, using distributed analysis systems. In 2007, LHC accelerator will start taking data. LHC will collide protons at the highest energy ?s=14TeV and luminosity L=1034 cm-2s-1 among all the other accelerators. Due to these performances, high precision measurements will be possible, comparisons between the Standard Model (SM) predictions and beyond the SM calculations will be accessible, any deviation from SM results means new physics.
To fulfil these requirements a high performance distributed computing system is needed. GRID technology is able to connect an unlimited number of computer systems and to distribute the tasks among all the connected nodes. In this project we propose an extension of IFIN-HH ATLAS-GRID facilities to a new center that will be built in INCDTIM in order to have more analysis power for physics processes that we want to study in proton-proton collisions in ATLAS experiment at LHC.
The main objectives of this project are following:
- Building up the distributed Romanian ATLAS-GRID system with two nodes: extension of IFIN-HH ATLAS-GRID system to INCDTIM-Cluj.
- Transmission speed measurements between IFIN-HH and INCDTIM-Cluj during sustained high speed data traffic.
- Entire system functionality tests as a single grid configuration.
- Task distribution and execution real speed depreciation measurements between the remote nodes.
- Romanian ATLAS-GRID distributed system performance tests with Monte Carlo simulations within ATHENA integrated software environment.
Results:
In 2005 our institute purchased the equipments - 2 servers, 1 switch KVM 8 port, 1 UPS 3000 VA, 1 rack 47 U - necessary for the system development and scientific Linux programs were installed. The system developed in the institute's node was connected with IFIN-HH node and the first tests offered promising results

Project title: Environmental exposure of pharmaceuticals in the Somes
Valley Watershed in Romania.
The objective of PHARMSOMES is to study the major entry routes leading to
exposure of the aquatic environment and subsequent fate in wastewater treatment
and river water in the Somes Watershed, Romania.
Regional-scale field studies will be conducted in the Somes Valley
watershed, the Cluj-Napoca area. The area is highly populated (around of 1 000
000 habitants) and has a big university hospital as well as drug factory and
cosmetics factory.After selecting of the relevant pharmaceuticals and personal
care products, the analytical methods based on Gas Chromatography (GC), Gas
Chromatography-Mass Spectrometer coupled system (GC/MS) and High Resolution Mass
Spectrometry (HRMS) will be established.
The occurrence of selected
pharmaceuticals and personal care products will be monitored in wastewater,
treatment plants and river water in the Somes Watershed. The field study will
provide for the first time in Romania, a dataset on the occurrence of
pharmaceuticals on a aquatic environment.

Partner in the Project (in the stage of contract):
Specific Targeted research project (STREP), Submitted under the Sub-Priority
1.1.6.3 (GLOBAL CHANGE AND ECOSYSTEMS) of the Sixth Framework Programme for
Community activities in the field of research, technological development and
demonstration (2002 to 2006), Area II, Topic II.3.2.
Acronym: NEPTUNE
Project full title: New sustainable concepts and processes for
optimization andupgrading municipal wastewater and sludge treatment
The scope of sewage treatment is changing: Up to date municipal wastewater
treatment plants (WWTP) were seen as an end-of-pipe treatment just before
discharge, having the aim to avoid eutrophication and hygienic health hazard in
surface water. Due to the global demographic trends as well as new legislations
(e.g. the Water Framework Directive, WFD) increased focus is put on quantity and
quality of effluents: more and more seen as interface between sanitation and
environment,WWTP are delivering resources to the environment and for human
activities (recharge of drinking water reservoirs, recycling of nutrient,
efficient energy use). This focus shift has implications on the quality goals
set for WWTP products:NEPTUNE will approach these tasks by focusing on
technology solutions allowing to meet present and future standards via upgrading
of existing municipal infrastructure (new control strategies with online
sensors; effluent upgrading with oxidation, activated carbon or wetland
treatment; safe sludge processing and reuse) as well as via new techniques (fuel
cell applications; new oxidation processes; production of polymer and phosphate
from sludge). By including pathogens and ecotoxicity aspects into life cycle
assessment studies (LCA), the project is helping to improve the comparability of
various technical options and propose a suitability ranking.
NEPTUNE addresses area II Water cycle, including soil-related aspects, topic
II.3.2 New concepts and processes in wastewater treatment of the Global Change
and Ecosystems-sub-priority 1.1.6.3.
In the work program of the fourth call of the sub-priority 1.1.6.3 area
II.3, research will include specific aspects ofintegrated urban water
management, the catchment scale and related technologies including the
management of scarce water resources in the context of global change as well as
the development of integrated approaches and tools for water-soil resource
management. In topic II.3.2 research objectives are explicitly focused on
leapfrog conceptual innovations in wastewater technologies and systems,
developing the most promising combination of innovative technologies and
processes, with defining a new set of advanced standards for wastewater
treatment that may offer sustainable tailor-made solutions to end-users. The
latter should be applied either for new installations, or for the upgrading of
existing plants.
Role in NEPTUNE: INCDTIM will contribute to workpackage 3 due
to their analytical experience and act as an important link for wastewater
activities (end-user workshop) for New EU Candidate Countries.
