Exposure to lead (Pb) is a global health problem for both humans and wildlife. Despite a dramatic decline in human Pb exposure following restrictions of leaded gasoline and industry and thereby an overall reduction of Pb entering the environment, Pb exposure continues to be a problem for wildlife species. Literature on scavenging terrestrial mammals, including interactions between Pb exposure and life history, is however limited.

对于人类和野生动物来说，接触铅 (Pb) 是一个全球性的健康问题。尽管随着含铅汽油和工业的限制，人类铅暴露量急剧下降，从而整体减少了进入环境的铅量，但铅暴露仍然是野生动物物种的一个问题。然而，有关食腐陆地哺乳动物的文献，包括铅暴露与生活史之间的相互作用，却很有限。
