Abstract

American black ducks (Anas rubripes) wintering in Tennessee during 1986 to 1988 were tested for exposure to lead. Twelve percent of the birds had blood lead concentrations exceeding 0.2 ppm. Significant differences in the prevalence of lead exposure were found for adults (14.4%) and juveniles (8.2%). Exposed birds had higher blood lead concentrations at one study site, corresponding with a lower survival index.

摘要

1986年至1988年期间在田纳西州越冬的美洲黑鸭（绿头鸭）被检测是否接触铅。12%的黑鸭血液铅浓度超过0.2 ppm。在成年黑鸭（14.4%）和幼年黑鸭（8.2%）中，铅暴露率存在显著差异。在一个研究地点，接触铅的黑鸭血液铅浓度更高，其生存指数更低。
