Se and Hg in Fish Collected Near Power Plants

Brooks Applied Labs’ data was featured prominently in a recent Environmental Toxicology and Chemistry journal article titled, “Selenium and Mercury in Freshwater Fish Muscle Tissues and Otoliths: A Comparative Analysis”. Authors Robin Reash et al. presented a study where they measured mercury (Hg), methylmercury (MeHg), and selenium (Se) in muscle tissue and otoliths from 12 species of fish collected from locations influenced by power plant wastewater. There were interesting differences between Se and Hg in their correlation between concentration in the tissues and otoliths and ecological/exposure factors, perhaps explained by the different manners in which Se and Hg bioaccumulate.
