PCB and organochlorine pesticides in northern fulmars ( Fulmarus glacialis) from a High Arctic colony: Chemical exposure, fate, and transfer to predators
Abstract Organochlorine contaminant concentrations, associated fugacities, and stable isotopes of nitrogen (δ 15 N) are reported for liver, whole body homogenate, and opportunistically collected samples of prey (amphipods), stomach oils, digestive tract contents, and guano for northern fulmars ( Ful...

Abstract Organochlorine contaminant concentrations, associated fugacities, and stable isotopes of nitrogen (δ 15 N) are reported for liver, whole body homogenate, and opportunistically collected samples of prey (amphipods), stomach oils, digestive tract contents, and guano for northern fulmars ( Fulmarus glacialis ) collected at Cape Vera, Devon Island in the Canadian High Arctic.
