Pretreatment with selenium prevented the accumulation of hexavalent chromium in rainbow trout (Oncorhynchus mykiss) and reduced the potential health risk of fish consumption

Hexavalent chromium (Cr6+) is a toxic element in environment. Selenium (Se) is an essential micronutrient trace element for living organisms and can ameliorate the adverse effects induced by Cr6+. However, the correlations between Se and Cr in fish have been rarely reported. The present study focused on the antagonistic effects of Se on Cr-induced accumulation in tissues (blood, gills, intestines, liver, kidney and muscle) of rainbow trout....
