Persistent organic pollutant levels and the importance of source proximity in Baltic and Svalbard breeding common eiders
Abstract The distance to sources and the long‐range transport potential of persistent organic pollutants (POPs) are important in understanding the impact of anthropogenic pollution on natural seabird populations. The present study documented blood concentrations of POPs in the Baltic Sea (Tvärminne,...
