While epidemiological data typically contain a multivariate response and often also multiple exposure parameters, current methods for safe dose calculations, including the widely used benchmark approach, rely on standard regression techniques. In practice, dose-response modeling and calculation of the exposure limit are often based on the seemingly most sensitive outcome. However, this procedur...

Mercury concentrations in the Laurentian Great Lakes waters are among lowest reported literature, while game fish approach consumption advisory limits, particularly Superior, Huron, and Michigan, indicating efficient methylmercury transfer from water to fish. To determine if increased efficiency is evident within lower food web, we measured (2010–2018) mercury dissolved organic carbon (DOC) wat...

Abstract The Greenland Ice Sheet is currently not accounted for in Arctic mercury budgets, despite large and increasing annual runoff to the ocean socio-economic concerns of high levels organisms. Here we present concentrations meltwaters from three glacial catchments on southwestern margin evaluate export downstream fjords based samples collected during summer ablation seasons. We show that di...
