Influence of oil, drill fluid and heavy metals on acid peptid-hydrolase activity of fish skeletal muscles

Researched pollution effect of an aquatic environment by crude oil, a drill fluid, heavy metals on acid pep-tid-hydrolase activity of skeletal muscles in yearling Rutilus frisii kutum, Neogobius melanostomus affinus, Cyprinus carpio and Rutilus rutilus caspicus in modelling experiment. Parameters of protein metabolism are informative enough parameters of changes in functional condition of an organism at anthropogenic im-pact. Changes in proteolytic activityof skeletal muscles of fishes are shown. Increase of acid peptid-hydrolase activity in skeletal muscles homogenates is noted at chronic pollutant influence. We considers these changes as adaptive organism responses of fishes to toxicants presence in an aquatic environment.
