摘要 考虑到枪杀动物遗骸中铅弹药残留的频率，鸟类食腐动物中铅暴露的高发生率并不令人惊讶。由于影响的潜伏期、发现尸体的可能性低以及检测亚致死铅负荷的健康表现的困难，对人口的影响可能被低估。有充分的理由预期亚致死铅是有害的，特别是考虑到大量人类健康文献提供了与极少量铅相关的多种不利影响的证据，并暗示脊椎动物的铅生理学大致相似。对银鸥（Larus argentatus）生长和行为的详细实验研究，涉及发育中的银鸥（Larus argentatus）的剂量和控制，以及其他物种的形态和生理反应的报告，为了解亚致死铅暴露对野生种群的影响提供了见解。因此，有必要进一步研究铅对鸟类食腐动物的亚致死影响，并且可能受益于骨铅测量和羽毛分析的进步，特别是在可以对现场活禽进行良性评估的情况下。
Abstract The high incidence of lead exposure being reported in avian scavengers is not surprising, considering the frequency with which lead ammunition residues occur in the remains of gun-killed animals. Population impacts likely are underestimated because of latency of effect, low probability of carcass discovery, and the difficulty of detecting the health manifestations of sublethal lead burdens. There are good reasons to expect that sublethal lead is harmful, especially in view of the considerable body of human health literature providing evidence of multiple adverse effects associated with very small amounts of lead, together with the implication that lead physiology is broadly similar among vertebrates. A detailed experimental study of growth and behavior involving dosing and controls in developing Herring Gulls (Larus argentatus), and reports of morphological and physiological responses in other species, offer insight into the implications of sublethal lead exposure on wild populations. Further studies of lead's sublethal effects on avian scavengers are therefore warranted and may benefit from advancements in bone-lead measurement and feather analysis, particularly where lead burdens can be benignly assessed among live birds in the field.
