| Abstract: | Some laws governing the self-purification of marine waters from oil products have been considered using the Sea of Azov and the NW shelf of the Black Sea as models. A number of principally important features of this process have been established including marked spatial heterogenity, and capacity for a sharp decline in the efficiency of destruction during anthropogenic transformations of marine ecosystems, etc. On the basis of a special mathematical model and numerous experiments, an estimation in the first approximation was made of the efficiency of the self-purification of the areas investigated and their characteristic regions. The value obtained is significantly smaller than the actual amount of oil products entering the sea as runoff. A number of recommendations have been made on the use of self-purification values for establishing standards for discharges of waste waters. |
