The antioxidant system in various organs of rapana (Rapana venosa) has been studied in condition of contamination of medium with copper ions (5 and 10 MPC) and sodium dodecyl sulphate (5 and 20 MPC). The most significant changes in the antioxidant status of cells occurred mainly during the first hours (three-24 hours) of exposure to toxic compounds. At the end of observations (72 hours) stabilization of the main parameters of the antioxidant system and return of its main indicators to control values were noted. Ktenidiy proved to be the most sensitive organ reacting to toxic doses of both copper and sodium dodecyl sulphate in the medium. Nephridiy cells turned out to be weakly susceptible to the action of the studied toxicants. The high lability and power of the antioxidant system of rapans provides a significant adaptive potential for the mollusk.
