| Abstract: | Model experiments with oil-polluted bottom sediments and aquatic organisms (bacteria, protozoa, rooted plants, worms, maggots insects, mollusks, crustaceans, benthos-eating fish), whose life cycle is associated with the bed of water bodies, where used to establish the lethal, sublethal, and threshold concentrations, as well as the maximal allowable oil concentration in bottom sediments as a standard established basing on the response of most sensitive test-organisms. The established standard??0.02 g/kg absolutely dry bottom sediment??was validated in rivers of the Ob basin and approved as a regional standard for water bodies of Khanty-Mansi Autonomous Area (Yugra). |
