[Biological effects of chemicals used in oil and gas extraction and purification of water bodies polluted with oil].

Hemopoietic system and liver are primary biologic targets damaged. That was proved by evaluation of biologic effects induced by preparations widely used in extraction of oil and gas, in purification of water from oil. Phosphorus organic compounds induce gonadotoxic effects. Surface-active chemicals and phosphorus organic compounds are similar in general toxic effects, but differ in specific influence.
