This cross-sectional study examined the association between environmental lead measurements surrounding a Los Angeles County battery recycling facility and the blood lead levels of the children living nearby. Environmental lead measurements and blood lead levels of young children living in a community adjacent to a stationary lead source were compared to those living in a community without a stationary lead source. Predictors of blood lead level were identified. The blood lead levels of the children living near the secondary lead smelter were within the normal range (< 5 micrograms/dl). The absence of ground cover was associated with slightly increased blood lead levels; however, this increase was not of biological significance. Lead levels in surface soil near the stationary lead source were elevated compared to the control community; however, the soil affected community, which may be due in part to controls recently installed at the stationary lead source.
这项横断面研究调查了洛杉矶县一家电池回收设施周边环境铅测量值与附近居住儿童血铅水平之间的关联。将居住在固定铅源附近社区的幼儿的环境铅测量值和血铅水平与居住在无固定铅源社区的幼儿进行了比较。确定了血铅水平的预测因素。居住在二次铅冶炼厂附近的儿童血铅水平在正常范围内（<5微克/分升）。地表无植被覆盖与血铅水平略有升高有关；然而，这种升高并无生物学意义。与对照社区相比，固定铅源附近表层土壤中的铅含量升高；不过，土壤受影响的社区情况，这可能部分归因于固定铅源最近安装的控制措施。
