ResumoPorphyrin patterns were determined by high-performance liquid chromatography (HPLC) in archived Herring Gull, Larus argentatus, chick livers which were collected in 1973 and 1974 from two locations in the Great Lakes of North America (Port Colborne, at the eastern terminus of Lake Erie and Scotch Bonnet Island, in eastern Lake Ontario). The results show that liver highly carboxylated porphyrins (HCPs) were elevated in the livers of half of the chicks from Scotch Bonnet Island. The importance of measuring HCPs and not simply total porphyrins when using porphyria as a biochemical marker of wildlife exposure to polyhalogenated aromatic hydrocarbons (PHAHs) is shown.
