| This paper reports on Pb and Cd concentrations in the tissues of 76 individuals of 16 rare bird species found dead across Korea. In most of species, Pb concentration was higher in kidney and bone than in liver. The range of the mean liver Pb was 0.47 (Cygnus cygnus)¡3.74 §¶/wet g (Asio flammeus). Based on hepatic Pb concentrations, 39 (51.3%) of the 76 individuals were classifed as background level (¡´2§¶/wet g), 35 (46.1%) were elevated level (¡µ2§¶/wet g) and 2 (2.6%) were poisoned level (¡µ10§¶/wet g). These results were indicated many rare birds were suffered from chronic Pb exposure. Cd concentration was generally higher in kidney than in liver and bone. The range of the mean kidney Cd was 0.06 (Bubo bubo)¡l.75§¶/wet g (falco subbuteo). Only one of the 76 individuals had elevated Cd concentration (¡µ2.7§¶/wet g) in kidney. These results indicated most of rare birds had low Cd accumulations. |
