One-year monitoring program was organized with the aim to assess the quality of sediment and water in these Vojvodina watercourses: the Begej, the Sava, the Botos, the Tisza, the Tamis, the Danube and the Danube-Tisza-Danube (DTD) Canal regarding metal content (Cr, Cd, Cu, Ni, Pb, Zn, Hg) in them. Water was the 1st/2nd class by MPL of national requirements, except occasionally for the copper concentration on some locations. The highest concentrations of zinc, cadmium, chromium, copper and mercury were detected in the Begej sediment. Maximum nickel concentration was in the Sava sediment, and for lead in the Danube sediment.

Faculty of Science, University of Kragujevac (Serbia, Serbia and Montenegro), has developed SeLar Information System (Serbian Lake and Reservoirs Information System) which provides all the information of Serbian lakes and water reservoirs. Information system is needed for transfer of knowledge and informations, cooperation among participant in management and support of sustainable using of water resources. The paper presents the basic system components and some applications examples.

Consequently to eutrophication, from the beginning of July to the end of November there was a water bloom in reservoir Celije generated by three cyanobacterial species. Monitoring of that phenomenon indicates that cyanobacteria have become phytoplanktonic dominant residents in the course of significant part of the year.

The puddle Slatina is the old meander of the river Tamis. It is periodically fill with moderate salt and high alkaline (pH 9) water. During our investigation it was determined 65 algal taxa from 5 divisions. Qualitative analysis points out on the domination of Cyanophyta, Euglenophyta and Chlorophyta, while quantitative analysis indicate the dominance of Cyanophyta. During spring 2003, total number of algae was 1.026 x 10**6 cel/l. High values of chlorophyll a (20 microgram/l) and total number of algae, as well as low transparency point out the progressive eutrophication.

Dutch classification system for sediment pollution was applied at the Begej canal in Serbia (Serbia and Montenegro). The method used calculates the class of the sediment on the basis of the sediment composition, organic matter fraction and mineral clay fraction as well as data on ecological risks. Results obtained showed that sediment is heavily polluted and urgent remediation is necessary. The contamination consists of heavy metals, especially cadmium, copper and chromium (class 4). Regarding organic micropollutants some high levels of PCB's and organochlorine pesticides like DDT/DDD/DDE were found (class 3).

Perovic, N. | Radulovic, M. | Filipovic, S.(Biotehnicki institut, Podgorica (Serbia and Montenegro))
In this paper are represented the results of the pollution character of soils and water during the 2002. Taking into consideration the changes of analyzed parameters in during the analyzed period, there have been noticed strong periodical pollutions by organic substances, nutrients and industrial polluters with the growing tendency regarding frequency which make worse the quality of soil-water the drainage basin of the river Tara, unique in Europe is proposed. That is the reason why the monitoring of the mentioned potential, with support of the space informatics technology as the prerequisite of its management.

Biopollatm : Biosphère et pollution atmosphérique en zone rurale et périurbaine. Rapport de fin de contrat
2004
Le Thiec, Didier
Le projet BIOPOLLATM vise à mieux comprendre les interactions biosphère-atmosphère dans le domaine de la pollution atmosphérique. On cherche (1) à comprendre les modalités d’impacts de plusieurs polluants sur le fonctionnement des plantes et (2) le rôle de la biosphère comme source et puits dans la pollution atmosphérique locale et régionale. Des caractéristiques fortes de BIOPOLLATM sont (1) une intégration entre des approches biologiques et physiques, à l’interface des sciences de la vie, de la terre et de l’atmosphère, (2) l’objet d’étude privilégié qui sont les écosystèmes cultivés en zones périurbaines et (3) l’intégration d’échelle, allant de la plante à la région selon les thématiques scientifiques et appliquées concernées. Ce rapport fait un point sur l’avancement du projet après 2 ans de travail (le projet se poursuit dans le cadre de PRIMEQUAL notamment, avec un financement du MEDD/DPPR). Il se compose de trois parties : - un rappel sur les objectifs et l’organisation du projet - un rapport plus détaillé sur les travaux conduits, organisé en trois grands domaines : o impact de l’ozone sur le fonctionnement des couverts végétaux à différentes échelles et selon différentes approches, allant de la modification des enzymes impliquées dans la photosynthèse jusqu’à la modélisation de l’impact sur le rendement des cultures ; o échanges de polluants entre un couvert végétal et l’atmosphère, organisé autour du développement et la validation d’un modèle à résistance à deux couches, destiné d’une part à être utilisé par les écophysiologistes/agronomes pour estimer les quantités de polluant absorbées par la végétation et, d’autre part, à être utilisé comme interface surface-atmosphère dans des modèles de chimie atmosphérique ; o une présentation des bases de données créées et des dispositifs expérimentaux créés dans le cadre de ce projet pour l’étude des échanges de polluants entre les surfaces naturelles et l’atmosphère. Ces acquis perdureront au delà du projet et pourront être utilisés par nos équipes et d’autres pour la poursuite de ce type de travaux. - Une synthèse des résultats acquis et une présentation des perspectives de ce travail à échéance de deux ans.
