Abstract
Experimental studies provide evidence on the effects of sublethal concentrations of crude oil on the body of the carp fish. Experiments were conducted on carp over the age of two years. The experiment lasted 30 days. Samples were selected in 10, 20, 30 days from the experiments. The permeability of blood-brain and histohematogenous barriers (in muscle, liver) were determined in vitro by the colorimetric method. The histological environment of the fish brain was studied. It was stated that the exposure to sublethal concentrations of oil on fish increased the level of permeability of the neutral red through hemato-incirenical and histohematological barriers. It was found that on the 10th day of the experiment fish evolved compensatory-adaptive reactions. With the increase of toxicity exposure time on the 20–30th fish showed signs of destructive reactions of vital organs, as well as in the central nervous system.
