This study investigates the relationship among lead exposure (shot ingestion), current lead impregnation (liver lead values), current and previous lead impregnation (bone lead values), and lead excretion (feather lead) in nine species of waterbird from the Camargue (Rhone river delta), France. Results indicate that for individuals there is no readily predictable relationship between ingested shot and liver or bone lead concentrations. However, at the "population" level, and interspecifically, significant positive relationships exist between the susceptibility to shot ingestion and the degree of lead impregnation. Shoveler (Anas clypeata) proved to be an exception, with a high level of shot ingestion and no elevated tissue lead values. This is probably related to dietary factors. Species with a high degree of current lead contamination tended to be those that had also previously absorbed elevated levels of lead. Feather lead concentrations were not clearly related to the vulnerability of a species to shot ingestion or lead poisoning. There was no significant absorption of arsenic and antimony from gunshot associated with lead absorption.
本研究调查了法国卡马尔格（罗讷河三角洲）9种水鸟的铅暴露（摄入铅弹）、当前铅蓄积（肝脏铅含量）、当前和既往铅蓄积（骨骼铅含量）以及铅排泄（羽毛铅含量）之间的关系。结果表明，对于个体而言，摄入的铅弹与肝脏或骨骼中的铅浓度之间没有易于预测的关系。然而，在“种群”水平上，且在种间，铅弹摄入易感性与铅蓄积程度之间存在显著的正相关关系。琵嘴鸭（Anas clypeata）是个例外，其铅弹摄入量高，但组织铅含量并未升高。这可能与饮食因素有关。当前铅污染程度高的物种往往也是之前吸收了高水平铅的物种。羽毛铅含量与物种对铅弹摄入或铅中毒的易感性没有明显关系。与铅吸收相关的枪弹中，砷和锑没有显著吸收。
