Oxidative Stress in a Wild Population of the Freshwater Fish Hyphessobrycon Luetkenii Chronically Exposed to a Copper Mining Area: New Insights into Copper Toxicology

In this study, we examine markers of oxidative stress in the tetra Hyphessobrycon luetkenii collected from two locations in the copper contaminated João Dias creek (southern Brazil). Also, specimens were translocated from a clean reference section of the creek to a polluted stretch and vice-versa. Fish were held at in submerged cages for 96 h and then sacrificed. Nuclear abnormalities in erythrocytes and total antioxidant capacity, lipid …
