As a result of stay of carp (Cyprinus carpio L.) in water with the promoted concentrations of lead (0,2 and 0,5 mg/l) the common amount of leucocytes in blood decrease in 1,5 and 1,6 times in comparing to the control. Both concentrations of toxicant drew changes in a percentage of blood leucocytes: decline of number of mature forms – neutrophils, basophils and monocutes, increase of maintenance of young cells, in particular lymphoblasts, promyelocytes, myelocytes and metamyelocytes. Subject to the condition presence in the environment of lead ions in concentration 0,2 and 0,5 mg/l phagocytic activity of neutrophils decrease in 1,5 and 1,4 times in comparing to the control.
