This study shows a very strong association between preschool blood lead and subsequent crime rate trends over several decades in the USA, Britain, Canada, France, Australia, Finland, Italy, West Germany, and New Zealand. The relationship is characterized by best-fit lags (highest R2 and t-value for blood lead) consistent with neurobehavioral damage in the first year of life and the peak age of offending for index crime, burglary, and violent crime. The impact of blood lead is also evident in age-specific arrest and incarceration trends. Regression analysis of average 1985-1994 murder rates across USA cities suggests that murder could be especially associated with more severe cases of childhood lead poisoning.
这项研究表明，在美国、英国、加拿大、法国、澳大利亚、芬兰、意大利、西德和新西兰，学前儿童血铅水平与随后几十年的犯罪率趋势之间存在非常紧密的关联。这种关系的特点是最佳拟合滞后（血铅的R²和t值最高），这与生命第一年的神经行为损伤以及指数犯罪、入室盗窃和暴力犯罪的犯罪高峰年龄相一致。血铅的影响在特定年龄的逮捕和监禁趋势中也很明显。对美国各城市1985 - 1994年平均谋杀率的回归分析表明，谋杀可能尤其与儿童铅中毒的更严重病例有关。
