Autores: Nikolov Bogdan N, Salapatiyska Stanka D, Georgiev Dilian G

Resumen

The current paper studies the change of respiratory rate and survival of Dreissena polymorpha at short exposure to zinc under laboratory conditions. The experiment is lasted 96h and three different concentrations of ZnSO4.7H2O were used - 0.5 mg/l, 1.5 mg/l; 2.0 mg/l. Survival and intensity of breathing of Dreissena polymorpha decreases with the increasing concentration of zinc in the water.

Palabras clave: Zebra mussel Dreissena polymorpha oxygen deficit zinc.
