An increase of anthropogenic load and intake of organic matter and nutrients leads to extremely negative consequences for coastal marine ecosystems. This is due to the fact that organic matter, deposited in the bottom sediments, contributes to the consumption of oxygen for its oxidation. With a lack of oxygen on the processes of mineralization of organic matter, its accumulation occurs. Oxygen consumption and organic matter accumulation in bottom sediments lead to appearance of anaerobic conditions in sediments an...

This paper presents the results of the sea water heavy metals (Hg, Pb, Cd, As, Zn, Fe, Ni, Cu) content examination in the coastal area of the Sevastopol. The water pollution index was calculated using 4 parameters with the obligatory inclusion of dissolved oxygen. Determination of metal content in water samples was performed by the method of inductively coupled plasma mass spectrometer PlasmaQuant MS Elite (Analytik Jena, Germany). The determination of the concentration of each of the chemical elements in seawater...
