In order to collect information about the presence of priority and other substances whose quality standards are defined by Directive 2008/105/EC, the water and sediment quality monitoring was carried out in 6 sampling locations in four rivers and 14 sampling locations in protected areas in AP Vojvodina. The waters of the Carska Wetland, Ludas Lake and Danube River exceeded the quality standards for pentachlorobenzene, while the quality standard for cadmium was only exceeded in Carska Wetland. The priority substances detected in the sediment were lead, nickel, mercury, trifluralin, isomers of hexachlorocyclohexane (HCH), pentachlorobenzene, hexachlorobenzene, 4-octylphenol, naphthalene, anthracene, fluoranthene, benzo(b)-and benzo(k)-flouranthene, benzo(g,h,i)-perylene and indeno(1,2,3-cd)pyrene.

Research macroinvertebrates in the lower reaches of the River Veternica was conducted during 2008 in spring and summer season on nine sites, in period of reduced outflow of water from the Lake Barje, when the water level is often reduced to the biological minimum. The presence of 91 taxa from 13 groups of macrozoobenthos was detected. Groups of Diptera, Ephemeroptera and Trichoptera were presented with 18, while Megaloptera, Plesoptera and Nematomorpha with one taxon each. The spring has been allocated 69 and 70 taxa in summer. The average was separated 17 taxa. Average number of macrozoobenthos was 1440 ind/square m per site. The few types of macroinvertebrates were very abundant at the site before the river confluence into the South Morava River. Insects made up 66.4% of the total number of individuals, especially the numerous groups of Diptera with 45.7%, while the share of the group Aquatic amounted 31%. The largest shares of the total abundance of taxa were as follows: Chironomus thumma with 28.16%, Limnedrilus hoffmeisteri with 11.2% and Tubifex tubifex with 6.89% and Caenis macrura from 5.2%. The structural parameters indicate that diversity of macrozoobenthos reduces in downstream direction, reflecting degradation of ecosystems.

Since the year 2004 the water reservoir Kraljevac has been recognized as a Special nature reserve. Investigations of the water reservoir were done during the autumn (November) of 2009 at three localities. on the basis of the results obtained in this study Kraljevac reservoir water is moderately polluted and correspond to classes 2nd and 2nd-3rd based on physical, chemical, microbiological and hydrobiological parameters.

This paper presents results of measuring the contents of certain bio-indicators in samples of digestive gland and lung of mussels (Mytilus galloprovincialis). The results were obtained in the framework of the Program for monitoring ecological status in Montenegro during the 2009 and 2010 year. Biomonitoring program was conducted in accordance with the LBS Protocol (Protocol on the Protection of the Mediterranean Sea against pollution from land-based sources and land activities) and the criteria MED POL Programme (Mediterranean Pollution Control), which is compliant with the requirements of the European Environment Agency (EEA) and has established a system of reporting and data exchange with the EEA. The program includes the analysis of biomarkers in Mytilus galloprovincialis (Lamarc, 1819) (mussels), and dynamic sampling is 2 times a year (March and September). In order to assess the spatial distribution and temporal trends of pollution, followed by the response of various biomarkers presented at two positions in the coastal waters of Montenegro (Dobrota and Bijela) and three positions in Slovenia (bays Piran, Strunjan and Koper). Biomarker responses showed no difference between the positions of the different ecological status.

Concentration of lead (Pb), lame (Cr), copper (Cu) and cadmium (Cd) were detrmined in Cystoseira algae collected from the Montenegrin mediolittoroal, during the spring 2007. Samples of three species of Cystoseira algae (C. amentacea, C. barbata and C. compressa) were analyzed in order to have information on bioaccumulation of these elements and possibility to use these algae as biomonitors for heavy metal pollution. The data obtained for heavy metals were similar with other area of Mediterranean Sea, with exception for significantly higher concentration of copper, on Budva location.

The study aims to examine source apportionment of heavy metals of the surface sediments in the less than 63 micro m size fraction. An assessment of metals marine pollution was done in the sediment collected from ten locations along Montenegrin coast. The samples were dried and acid-digested and the metal contents (Fe, Mn, Cu, Zn, Cr, Co, Ni) were determined using a flame atomic absorption spectrometry. The results were compared with the literature data from Mediterranean countries.

Species belong to class Holothuriidae play significant role in the transmission of energy within the sea bottom biocoenoses. Their abundance and distribution have high impact on the biocoenoses dynamic and at the same time it can be use as indicator of the anthropogenic influence on marine environment. Data present in the paper are results of the investigation of their distribution on the Montenegrin shelf and comparison with neighboring area. Obtained results show presence of six species, and two of them are for the first time recorded for a given area.

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.

In this paper the results of preliminary investigations of microbiological quality of seawater and sediment are presented. Analyses are performed by membrane filtration. The samples were collected near the sawage outfalls in Bokakotorska bay. It is noticed much higher number of bacteria – indicators of fecal pollution in sediment surface that seawater overlaying the sediment. Concentrations of bacteria diminished in layers of sediment laying deeper that sediment surface. Influence of wastewater is the most evident on 1 and 3 positions.

The content of major elements Al, K and Mg was investigated in surface sediment samples from the coastal area of the South-eastern Adriatic, in sediment fraction less than 2 mm. Obtained results were used to present horizontal spatial distribution of these elements in sediment of the area studied. The spatial distribution of elements showed similarities in the behavior of Al and K, while the distribution pattern of Mg in sediment was contrary to Al and K. It can be noticed that the sediment composition in terms of these elements reflects the geological characteristics of the continental hinterland in the South-eastern Adriatic coastal zone.
