Microbiological monitoring of river water quality is obligatory for use-related aspects such as drinking water production, irrigation and recreation. Assessment of the microbiological quality of water and sediment at the Velika Morava River was performed at five sites, during 2010 and 2011. By applying standard procedures for sanitary correctness and organic load assessment, total of 16 parameters were analyzed. Results of analysis indicated that microbiological water quality of the Velika Morava River is unsatisfactory.

Marine sediments naturally contain arsenic at low concentrations. Increased concentrations could come from natural sources such as volcanic activity, hydrothermal vents and others, but they are usually the result of human activities. The largest number of arsenic compounds possesses toxic properties and due to this arsenic is classified as hazardous substances to the environment and biological species. Therefore, arsenic and its compounds are subject to chemical and biological analysis of sediments. Based on the analysis of sediment samples for arsenic content, this paper presents arsenic spatial distribution in the investigated area of the South-East Adriatic.

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.

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.
