Analysis of short-term effects of heavy metals on protein metabolism in carp

The article is devoted to assessing the toxic effects of heavy metals during short-term exposure to fish. the aim of the study was to study the indicators of protein metabolism in carp after exposure to 10 maximum permissible concentrations of lead acetate, cadmium, zinc and copper. During the experiment, 5 groups of fish were formed - 1 control group (10 fish), 4 experimental groups - 10 fish each, which were contained in solutions of lead acetate (Pb(CH3COO)2) with a concentration of 0.06 mg/l (exceeding the maximum permissible concentration of lead for fisheries waters by 10 times), cadmium acetate (Cd (CH3COO)2) with a concentration of 0.05 mg/l, copper acetate (Cu(CH3COO)2) with a concentration of 0.01 mg/l and zinc acetate (Zn (CH3COO)2) with a concentration of 0.1 mg/l, respectively, for 4 hours. The concentration of total protein, albumins, and globulins in blood serum was studied. An in crease in total protein and serum globulins was found when evaluating the effect of all the studied metals, as well as a decrease in the concentration of albumins due to poisoning with zinc and cadmium acetate and an increase in the concentration of albumins due to poisoning with lead and copper acetate.
