While blood lead levels (BLLs) in many western countries have progressively declined since 1976, in Nigeria high BLL continue to be documented not only in exposed workers but also in "unexposed" control subjects. The problem of environmental lead exposure has hitherto gone unaddressed by both researchers and health policy makers in Nigeria despite the immense public health importance. Continued high BLLs in Nigeria cast doubt on researchers' ability to find real "unexposed control subjects" in future studies, and point to the importance of controlling environmental lead exposures.
自1976年以来，许多西方国家的血铅水平（BLLs）已逐渐下降，但在尼日利亚，不仅在接触铅的工人中，而且在“未接触”的对照人群中，仍有高血铅水平的记录。尽管环境铅暴露问题具有巨大的公共卫生重要性，但尼日利亚的研究人员和卫生政策制定者迄今都未对其加以解决。尼日利亚持续存在的高血铅水平使人怀疑研究人员在未来研究中能否找到真正的“未接触对照人群”，并凸显了控制环境铅暴露的重要性。
