Environmental cadmium exposure and metabolic responses of the Nile tilapia, Oreochromis niloticus

摘要

The contamination of water by metal compounds is a worldwide environmental problem. This study was undertaken to evaluate the impact of short-term cadmium exposure on metabolic patterns of the freshwater fish Oreochromis niloticus. The fist were exposed to 320, 640, 1280 and 2560 μg/1 sublethal concentrations of Cd~++ (CdCl_2) in water for 7 days.
