Patterns of mercury and selenium exposure in Minnesota common loons: Data

The concentrations of selected metals (mercury [Hg], lead, cadmium, selenium [Se], and aluminum) were determined in common loon (Gavia immer) blood samples collected from across a broad area of Minnesota. The observed pattern of loon Hg exposure was related to Hg concentrations in a standardized 12-cm whole organism yellow perch (Perca flavescens), based on fish Hg records from lakes throughout Minnesota, using the U.S. Geological Survey National Descriptive Model for Mercury in Fish.
