We examined the effects of changes in Rhode Island's Lead Hazard Mitigation Law in 2005 on children's blood lead levels.
We used 2005 to 2009 data from Rhode Island's Lead Elimination Surveillance System; city tax assessor records in Central Falls, Pawtucket, Providence, and Woonsocket, Rhode Island; and records of conformance to the state's lead hazard mitigation law, to assess the extent to which legislation changes resulted in minimizing children's exposure to lead.
During the 5-year study, the proportion of properties that complied with the new law increased for properties that housed young children. However, the majority of rental properties did not comply with the law. Children's lead levels declined by approximately 1 microgram per deciliter on average in properties that did comply, demonstrating that the law could have a protective effect for children.
Legislation changes increased the proportion of properties that were certified as nonhazardous, leading to decreased blood lead levels for children living in these properties. However, legislation cannot be a highly effective primary prevention strategy if it does not cover all properties where children live and is not strictly enforced.
我们研究了 2005 年罗得岛州《铅危害缓解法》的修订对儿童血铅水平的影响。
我们使用了罗得岛州 2005 年至 2009 年的《铅消除监测系统》数据、中央瀑布市、保茨维尔市、普罗维登斯市和沃索尼克市的城市税务评估记录，以及符合该州铅危害缓解法的记录，评估了立法变化在多大程度上使儿童最小化接触铅。
在 5 年的研究期间，符合新法的住房中儿童居住的房产比例增加了。然而，大多数出租物业不符合法律规定。在遵守法律的物业中，儿童的血铅水平平均下降了约 1 微克/分升，这表明该法律可以对儿童起到保护作用。
立法修订增加了被认证为无危险的房产比例，从而降低了居住在这些房产中的儿童的血铅水平。然而，如果立法不能覆盖所有儿童居住的房产，且没有得到严格执行，那么它不能成为一种非常有效的初级预防策略。
