| | PCBs, DDE, DDT, and TCDD-EQ in Two Species of Albatross on Sand Island, Midway Atoll, North Pacific Ocean - ... |
 | | The Laysan albatross diet consists primarily of ommastrephid squid (68% of the diet); the remainder of the diet consists of approximately 9% fish, 9% crustaceans, and 4% coelenterates [7]. |
 | | In 1969, concentrations of PCBs and DDE in visceral fat of Laysan albatrosses were 22.3 mg/kg and 13.7 mg/kg, respectively; whereas visceral fat of fl-footed albatrosses contained a mean concentration of 15.3 (7.5-21.3) mg/kg and 15.3 (5.1-22.7) mg/kg of PCBs and DDE, respectively. |
 | | The HQ for fl-footed albatrosses was approximately 10, which, based on observations in populations of fish-eating birds of the North American Great Lakes, would be expected to be causing subtle population-level effects, such as embryo lethality [1,2] and deformities [14,27,28]. |
