Is shown, that the influence of such ions of heavy metals,
as a nickel, cobalt, manganese, tin, zinc and the cadmium in the concentration
10-6-10-4 М results in lowering of Na2+, K+-ATPase
activity of loach embryo at different stages of blastomer divisions,
thus the character of these changes coincides character of changes
of transmembrane potential during period of blastomer divisions under the
heavy metal influence.
