The pollution water and bottom sediments of the Caspian Sea by petroleum products

Salahova SZ, Sh Тоpchievа А

Had been studied the degree of water contamination and bottom sediments of the Caspian Sea with the oil products. For the investigation period in the waters of the oil fields of South Caspian are fixed 66 species of zooplankton. It was revealed that petroleum hydrocarbons in concentrations of 0.05-0.5 mg/l, as a rule, don't affect survival of marine organisms, if their toxic effects are not exacerbated by the action of other toxicants. It is shown that during the study from 2011 to 2013, observing a tendency of decreasing the content of petroleum hydrocarbons in sea water, exception to oil-gas field "Gurgan". It is established the maximum value of abundance and biomass of zooplankton (1331 ind./m3 and 8.757 mg/m3) for the summer season on the field of Oil Rocks. It was noted the current lack of significant negative consequences for marine ecosystems and biological resources of the Caspian Sea from oil and gas development. This may indicate a some improvement and general stabilization of the ecological situation in the entire offshore of the Caspian Sea.
