Fecal lead excretion (PbF) was studied in young children with elevated lead exposure. PbB was generally 40-70 microgram/dl. The children's home environments were classified as to lead-base paint hazard and traffic density. There was a significant correlation between paint hazard classification and PbF but not between traffic density and PbF. There also was a correlation of PbB with paint hazard classification. Long-term fecal collections were instituted using 10 children who lived in high hazard homes and three children with low PbB's, whose PbF's were considered normal. Among the children living in high hazard homes, median fecal lead excretion generally was only moderately elevated. Grossly elevated amounts of led were found only occasionally and only in a few of the children. Movement of two children from a high hazard home to a low hazard home resulted in prompt and substantial reduction in PbF. By contrast, PbB fell only very slowly.
对铅暴露水平升高的幼儿的粪便铅排泄（PbF）进行了研究。血铅水平（PbB）一般为40 - 70微克/分升。根据铅基涂料危害和交通密度对儿童的家庭环境进行了分类。涂料危害分类与PbF之间存在显著相关性，但交通密度与PbF之间不存在显著相关性。PbB与涂料危害分类之间也存在相关性。对10名居住在高危害家庭的儿童和3名血铅水平低（其粪便铅排泄被认为正常）的儿童进行了长期粪便收集。在居住在高危害家庭的儿童中，粪便铅排泄中位数一般仅适度升高。仅偶尔在少数儿童中发现铅含量大幅升高。两名儿童从高危害家庭搬到低危害家庭后，粪便铅排泄迅速大幅下降。相比之下，血铅水平下降得非常缓慢。
