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.

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.

The fact is that in the world today water and land represents limited life resources which are more and more degrade and disturbed, mostly by anthropogenic influence. Especially water (seas, rivers, lakes) is exposed to various types of pollution. The fact is that in the world today water and land represented limited life resources which are more. That why in present time we conduct numerous scientific researches to examine, advance and protect our environment, especially water as a limited and delicate natural resource. In this work results from April to September 2011 are presented, which comprised analyses of samples from 8 stations in Boka Kotorska Bay. The main aim was to estimate trophic level, of determining the concentration of the physico-chemical parameters, chlorophyll a and TRIX index in Boka Kotorska Bay.

The microbiological quality of the groundwater was monitored by determining relevant physiological groups of bacteria (organotrophic bacteria) which are indicators of water organic pollution. Standard high nutritive medium (Nutrient Agar) and low nutritive medium (R2A agar) were used. The enzymatic activity was also estimated based on IFA determination (index of phosphatase activity). According to the number of organotrophic bacteria and categorization by Kohl (Kohl, 1975) water is generally classified in category II. IFA showed variation of water quality, which varied from polluted to very pollute. The results showed organic pollution of groundwater and confirmed the sensitivity of enzymatic methods. In addition, cultivation methods confirmed superiority of low nutritive media.

Complex hydrodynamics and thermal regimes of temperate lakes have a major impact on temporal and spatial distributions of water quality indices. Transport processes in lakes are driven primarily by external forces such as wind and solar radiation but also depend on the inflow and outflow regimes. This paper presents a simplified ID model developed to calculate seasonal variations in vertical distributions of temperature and dissolved oxygen in Lake Zavoj in southern Serbia. Model results that were based on monthly averaged meteorological data are in good agreement with measured vertical profiles of temperature and dissolved oxygen. The simplified model is an efficient tool for long-term prediction of water quality indices in deep, medium and long residence time lakes.

In order to determine the stable isotope content of hydrogen (2H/1H) and oxygen (18O/16O) from surface water and the Zavoj Lake, a sampling campaign was carried out in November 2011. Vertical profiles of water samples were collected in the sections close to the dam to check whether there was any detectable influence from the inflowing Visočica River and wheter there was a vertical isotopic stratification of the lake water. Temperature gradient of up to 5.5 deg C between surface and about 60 m depth is observed. Dominant process of mixing the inflowing Visočica River and water leaking from diversion tunnel appear close to the dam.

This paper provides an assessment of the Mlava River on the Danube River sediment quality. The contents of Zn, Cu, Pb, Cr, Ni, Cd and As were detected in the surface sediment. Based on the obtained concentrations of these seven metals sediment quality pollution category was determined with respect to PLI (pollution load index) and I geo (geo-accumulation index). It is found that M4 site, according to PLI and I geo (As and Cd) values can be classified as very highly polluted.
