Abstract
Research results about the effects of cadmium and zinc ions on the histological structure of cells of antennal glands of marbled crayfish Procambarus fallax (Hagen, 1870) f. virginalis
(Decapoda) are presented in the article. It is determined that size of glandulocytes and their nuclei affected by to heavy metals naturally reduces however nuclear-cytoplasmic ratio is stably preserved, which is probably the excretory system adaptive response to the impact of heavy metals ions.
Keywords: cadmium • zinc • marbled crayfish • glandulocytes • Procambarus fallax (Hagen, 1870) f. virginalis
