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.
研究了在体铬暴露对虹鳟（Salmo gairdneri）几种组织中钠钾 - ATP酶和镁 - ATP酶活性的影响。所研究的组织有：肠道、鳃、肝脏和肾脏。测定了对照虹鳟以及暴露于2.5毫克铬/升（以铬酸盐形式）48小时的虹鳟的组织铬含量。铬暴露后，观察到钠钾 - ATP酶活性受到抑制，但镁 - ATP酶活性未受抑制。这些结果可能部分解释了六价铬对鱼类的有害影响。
