The paper presents a comparison of measurements of selected organic pollutants in various water matrices, in order to assess the impact of the matrix on the accuracy of pollutant analysis. Selected compounds were from class of phenols (p-nitrophenol, 3,5-dichlorophenol)and organochlorine pesticides (isomers of hexachlorocyclohexane (HCH), heptachlor, aldrine, heptahloroepoxide, 4,4'-DDE, dieldrine, endrine, 4,4'-DDD, endrin aldehyde, 4,4'-DDT, endosulfan sulfate). Apart from distilled water and synthetic aqueous matrix (salt addition in distilled water according to DIN EN 12902 standard), natural matrix was also used in the analysis – surface water (River Danube in Novi Sad – DOC (dissolved organic carbon) 2-6 mg/l, suspended matter content 30 mg/l).

Constant and highly productive agricultural productivity in the last decades has a tightly connected to irrigation. It is necessary to monitor the irrigation water quality in order to prevent or mitigate negative consequences on yield, soil and irrigation equipment. Besides the major waterways, the detailed canal network has great potential as a water resource. Peculiarities of this kind of water resources require monitoring of water suitability. During a three-year period of research, water was sampled on some localities in Backa and Banat (Serbia). The results of the research indicate that the water quality does not meet the demands proposed by the classifications. This proves the fact that during the irrigation period, it is necessary to monitor the irrigation water quality.

The Djerdap 1 Hydropower Plant (Djerdap 1 HPP) was joint projects of Yugoslavia and Romania, based upon the principles of equal benefits. The primary functions of the Djerdap 1 HPP are to effectively utilize the available hydropower potential of the Danube and to provide a full navigational capability under any hydrologic conditions. The utilization of the hydropower potential was conditional upon the provision of a Riparian Land Protection System for the Djerdap 1 reservoir, and the timely prevention of any adverse impacts due to the alternation of the natural regime as a result of backwater. ongoing enhancement of the Riparian Land Protection System and study of the various impacts have enabled a continual backwater increase and a resulting increase in the output of high quality power, with no significant risk of adverse impacts.

This paper offers a new mechanism in order to Nash-implement a Pareto optimal level of ambient pollution. As usuas in the literature on non point source pollution, the proposed scheme is not conditional on individual emissions, since they are not observable; rather it is conditional on aggregate emission. But the novelty here is that we do not assume the regulator knows the agents'preferences, with which he could identify the target level of aggregate emission. Our mechanism dispenses with this information, yet it achieves Pareto optimality provided that the number of agents involved in the problem is known.

La chlordécone, insecticide organochloré, était utilisée pour lutter contre le charançon du bananier (Cosmopolites sordidus) de 1971 à 1993. La chlordécone est peu mobile et se dégrade à une vitesse très lente, voire nulle dans les sols aérés. Sa persistance est donc longue, et la dépollution artificielle n'est pas opérationnelle actuellement. Cependant les sols restent fertiles même si ils constituent la principale réserve et source de pollution. Il faut donc gérer cette pollution. Cela implique des changements au sein des agrosystèmes, tant sur le choix des productions possibles que sur certaines pratiques agronomiques pour réduire les impacts sanitaires. Pour les espèces cultivées sur les parcelles polluées, certains organes sont très contaminés (tubercules), d'autres indemnes (fruits d'arbres, banane, ananas, tomate, etc.). Un outil de gestion est disponible pour les producteurs afin d'anticiper le choix des cultures et de réduire le risque d'exposition des consommateurs. Réciproquement, les systèmes de culture ont une incidence sur la dispersion de la molécule à l'échelle d'une parcelle et d'un bassin versant. La chlordécone contamine les ressources et les organismes aquatiques via les eaux de percolations issues des parcelles polluées. Cet article fait le point sur les principaux résultats disponibles et les projets en cours sur la gestion des agrosystèmes et les processus de transferts de la chlordécone vers l'environnement ainsi que leurs impacts sur les écosystèmes aquatiques.

The paper presents the results of diversity and distribution of thermophilic species of echinoderms in the continental shelf on Montenegro coast. The data show that explored area inhabited by eight species of which the sea cucumber Holothuria (Platyperona) sanctori for the first time is recorded and is new species for the fauna of Montenegro. Based on the fact that climate change affects the temperature rise of the sea water, especially the coastal area, the aim of this study was to determine the presence of thermophilic species of echinoderms, which can be the basis for further monitoring and tracking changes in the benthic biocoenosis of the southern Adriatic.

Mediterranean mussels, Mytilus galloprovincialis, are recognized bioindicators used in investigation of genotoxic pollution in the areas under the impact of anthropogenic activities. In July and August 2011 specimens of M. galloprovincialis were collected from 5 sites of Boka Kotorska Bay, Montenegro. Level of DNA damage was measured in gills, haemolymph and digestive gland with alkaline comet assay. Significant increase in DNA damage was detected in tissues of mussels collected from polluted sites comparing with mussels collected from the clean reference site Dobrota. The highest response to pollution was found in gills and digestive gland cells.

Based on all available data a review of introduced non-indigenous species is reported for the area of Montenegrian coastal sea (South-East Adriatic Sea). All together 11 species were recorded, three algae and eight animals. Monitoring of invasive species has been done partially only for Caulerpa racemose var. cylindracea, while for other species distribution and impact on autochthonous environment is unknown.

The concentrations of heavy metals (Cu, Zn, Cr, Pb, Cd and As) were measured in sea water and mussels at location in the Boka Kotor Bay which selected as result of increased anthropogenic impacts from land. Sampling was performed at three locations, Sv. Stasije, Herceg Novi and Žanjice in the fall 2006 and spring 2007. The majority of the microelements registered in higher concentrations in fall samples in 2006 than in spring samples 2007. The concentration of metals in the studied samples was present at different levels, and is beloved the maximum level allowed, except for yinc and lead in some locations.

Monitoring of ecological condition of the coastal sea of Montenegro has been carried out extensively since 1963 along with foundation of the Institute of marine Biology in Kotor (Montenegro). Recently, in accordance with recommendations of the Barcelona Convention, the LBS Protocol, the EU Framework Directive for coastal waters and domestic laws, in recent years has been carried out continuous monitoring of quality water, sediments, biota as well as ecological effects of pollution on constant monitoring positions in this southeastern part of the Adriatic. In this paper was given an over view of activities and the plan of long-term continuous monitoring of environmental quality and ecological condition of the coastal sea of Montenegro.
