INTEGRAL ASSESSMENT OF POLLUTION IN BOTTOM SEDIMENTS OF COASTAL AND OPEN-SEA AREAS OF THE BLACK SEA
Keywords:
the Black Sea, bottom sediments, contamination, integral indexes of pollutionAbstract
In 1992 the Ukrainian Research Centre of Marine Ecology (UkrRCME) organized several marine expeditions to the northern Black Sea; materials collected during three complex seasonal surveys are used in this work. It was revealed the main pollutants that make the impotent contribute to the integral level of contamination of the sea. At depths ranged from 9 to 2195 m pollutants deposited in the sea bed were mainly total petroleum hydrocarbons (TPH), DDT and its metabolites, and HCCH, the quantities of which were greater than maximum allowable concentrations (MAC). This fact should be considered when choosing a strategy of toxicological monitoring of the Black Sea for the purpose to optimize it.
