The effect of in vivo chromium exposure on Na/K-and Mg-ATPase activity in several tissues of the rainbow trout (Salmo gairdneri).
The effect of in vivo chromium exposure on Na/K-and Mg-ATPase activity was studied in several tissues of the rainbow trout, Salmo gairdneri. Those tissues studied were: intestine, gill, liver, and kidney. Tissue chromium levels were determined for control rainbow trout and trout exposed to 2.5 mg Cr/1 (as chromate) for 48 hours. After exposure to chromium, inhibition of Na/K-ATPase activity, but not Mg ATPase activity, was observed. These results may partially explain the detrimental effects of hexavalent chromium on fish.
