从1994年到1999年，美国住房和城市发展部含铅涂料危险控制补助计划评估研究了美国11个州2800多户家庭的干预经验。每种室内干预措施被归类为(按强度增加的顺序)(A)清洁/专色油漆；(B)完全重新粉刷；(C)完全重新粉刷加窗户处理；(D)窗户消减和其他成分的处理；(E)消除所有含铅油漆危害；或(F)消除所有含铅油漆。在干预后12个月和36个月期间，分别获得了1034和278个住宅的完整粉尘测试和环境数据。从完全重新粉刷到窗户减少再加上其他处理的各种策略将干预前的窗台和地板灰尘铅负荷的几何平均值减少到干预后36个月(对于完全重新粉刷，地板从16至5微克/英尺(2)减少到182到88微克/英尺(2)；对于窗户减少和其他处理，地板减少27-8微克/英尺(2)，窗台减少570-124微克/英尺(2))。完全减排将窗台和地板负荷从基线减少到干预后12个月[地板95-6微克/英尺(2)，窗台518-30微克/英尺(2)(36个月没有这一策略的数据)]。减少窗户铅危害是减少窗户上粉尘铅负荷的最有效措施，但这种处理需要与地板处理以及外部和土壤处理一起进行，才能最有效地控制地板上的粉尘铅。(C)2005 Elsevier Inc.保留所有权利。
From 1994 to 1999, the Evaluation of the US Department of Housing and Urban Development Lead-Based Paint Hazard Control Grant Program studied the intervention experiences of over 2800 homes in 11 states in the USA. Each interior intervention was categorized as (in order of increasing intensity) (a) cleaning/spot painting; (b) complete repainting; (c) complete repainting plus window treatments; (d) window abatement plus treatments to other components; (e) abatement of all lead-based paint hazards; or (f) abatement of all lead-based paint. Complete dust testing and environmental data were available for 1034 and 278 dwellings through 12 and 36 months postintervention, respectively. Strategies ranging from complete repainting to window abatement plus other treatments reduced geometric mean preintervention windowsill and floor dust lead loadings up to 36 months postintervention (reductions for complete repainting, from 16 to 5 mu g/ft(2) on floors and 182 to 88 mu g/ft(2) on sills; for window abatement plus other treatments, 27-8 mu g/ft(2) on floors and 570-124 mu g/ft(2) on sills). Full abatement reduced windowsill and floor loadings from baseline to 12 months postintervention [95-6 mu g/ft(2) on floors and 518-30 mu g/ft(2) on sills (data were not available for this strategy at 36 months)]. Window lead-hazard abatement was the most effective measure to reduce dust lead loadings on windows, but this treatment would need to be performed in conjunction with treatments to floors as well as exterior and soil treatments for the most effective control of dust lead on floors.
