众所周知，家庭表面的铅尘会导致儿童血铅水平升高。已经设计了几种粉尘收集方法来有效地测量Ž的铅负荷和/或铅浓度。1974年；美国HUD，1990年；Lioy等人，1993年，并且已经在Sayre和Katzel等人，1979年；Que Hee等人，1985；Davies等人，1987；McArthur，1992；Farfel等人，1994a，b；Lanphear等人，Ž等人的许多研究中进行了现场测试和比较。1995年；美国环保局，1995年；弗里曼等人，1996年。直到最近，还没有抽样方法的标准化。由于采样效率和分析技术的差异，这导致无法比较铅的负载量。使用预湿的毛巾在规定的模板内以固定的次数擦拭灰尘是一种广泛使用的方法
Lead dust on household surfaces is known to contribute to elevated childhood blood lead levels. Several dust-collection methods have been designed to effectively measure Ž lead loading andror lead concentration Vostal et al.,. 1974; US HUD, 1990; Lioy et al., 1993, and have been Ž field tested and compared in numerous studies Sayre and Katzel, 1979; Que Hee et al., 1985; Davies et al., 1987; McArthur, 1992; Farfel et al., 1994a, b; Lanphear et al.,. 1995; US EPA, 1995; Freeman et al., 1996. Until recently, there has been no standardization of sampling methods. This has led to an inability to compare lead loadings because of differences in sampling efficiency, andror analytical techniques. The use of premoistened towelettes to wipe up dust, within a defined template, with a fixed number of passes is a method that has been widely
