Abstract

This article presents the results of the study of the mechanical strength of the intestinal epithelial layer of carp after exposure to heavy metals (lead, cadmium, zinc and copper). The presence of "live" epithelial cells in intestinal preparations indicates a violation of the mechanical strength of the epithelial layer of the intestine, which, in turn, is a sign of poisoning. 3 series of experiments were carried out: 1) the Effect of 100 limit concentrations of heavy metals in fish, 5 groups of fish (carp) were used: control; group of fish contained in lead acetate (0.6 mg / l); cadmium acetate (0.5 mg/l); cupric acetate (0.1 mg/l); zinc acetate (10 mg/l); 2) the impact of the 1000 limit concentrations of heavy metals in Fish, used 4 groups of fish (control from the previous series): the fish contained in lead acetate (6 mg/l); cadmium acetate (5 mg/l); acetate, copper (1 mg/l); zinc acetate (10 mg/l). 3) the effect of 10000 limit of heavy metal concentration in Fish: 4 groups of fish contained in lead acetate (60 mg/l); cadmium acetate (50 mg/l); copper acetate (10 mg/l); zinc acetate (100 mg/l). The study showed that under the influence of 100 and 1000 limits of copper concentration, there is less mechanical strength of the intestinal epithelium, as well as under the influence of 10,000 limits of cadmium concentration.
