Phosphorus Balance in Fishes under the Influence of Heavy Metals (Cr6+, Ni2+) Contained in the Aquatic Environment

V. P. Gandzyura

Essential disturbances in phosphorous balance were established in freshwater fishes as the responses to enhanced contents (from 1 MPC and more) of Cr6+ and Ni2+ in their aquatic environment. The effects of these metals are manifested in a considerably increased level of phosphorus excretion and its decreased content in fish body.
