A Duke University-led study has found dangerously high levels of mercury and its more toxic chemical cousin, methylmercury, in soils, sediments and rivers near artisanal gold mines in the West African nation of Senegal.
"Nearly every sample we collected from in and around four mining villages contained mercury concentrations higher than regulatory standards set by the World Health Organization and U.S. Environmental Protection Agency," said Jacqueline Gerson, a Ph.D. student in ecology at Duke.
