Study site locations: New York - Hudson River - Belted kingfishers

Belted kingfishers accumulated PCBs from the Hudson River.  The pattern of PCB congeners was characterized by a higher representation of lower-numbered congeners than found on other rivers. The higher prevalence of the lower numbered congeners and lower prevalence of the higher-numbered congeners is consistent with Aroclor 1016 and 1242 being the source of the PCBs on the Hudson River.
