Abstract

Sea gulls are high trophic level consumers in the coastal environment, and thus, which have been widely used to monitor contamination biomagnified through a food web. However, such monitoring studies using sea gulls have been rare in the Korean literature. The National Environmental Specimen Bank chose eggs of a black-tailed gulls (Larus crassirostris) to serve as an environmental specimen for the long-term monitoring of the coastal ecosystem affected by terrestrial pollutants. Black-tailed gull eggs were collected from Baengnyeongdo, Hongdo and Uleungdo, and their DDTs and total mercury content were determined. The highest concentration of DDTs was 231.6±106.1 μg/kg wet in Baengnyeongdo, followed by 230.0±123.8 μg/kg wet in Ulleungdo, and 117.7±18.3 μg/kg wet in Hongdo. In addition, total mercury was detected at 414.5±97.6 μg/kg wet in Ulleungdo, 363.9±123.6 μg/kg wet in Hongdo, and 237.5±42.3 μg/kg wet in Baengnyeongdo. Relatively high concentrations of the target pollutants were recorded in specimens from Ulleungdo. Additional comprehensive and prolonged studies are required to elucidate spatial and temporal patterns of contamination in black-tailed gull eggs with regard to monitoring contaminant trends in eggs and prey.
