This prospective study describes the impact of residential lead-based-paint hazard remediations on children with mildly elevated blood lead levels.
Changes in blood lead levels were observed following paint hazard remediation alone and in combination with soil abatement.
After adjustment for the confounding variables paint hazard remediation alone was associated with a blood lead increase of 6.5 micrograms/dL (P = 0.5), and paint hazard remediation combined with soil abatement was associated with an increase of 0.9 microgram/dL (P = 36).
Lead-based-paint hazard remediation as performed in this study, is not an effective secondary prevention strategy among children with mildly elevated blood lead levels.
本前瞻性研究描述了住宅铅基涂料危害修复对血铅水平轻度升高儿童的影响。
观察了仅进行涂料危害修复以及与土壤清理相结合后血铅水平的变化。
在对混杂变量进行调整后,仅涂料危害修复与血铅水平升高6.5微克/分升相关(P = 0.5),而涂料危害修复与土壤清理相结合则与血铅水平升高0.9微克/分升相关(P = 36)。
本研究中所进行的铅基涂料危害修复,对于血铅水平轻度升高的儿童而言,并非有效的二级预防策略。
