The suitability of several commercially available wipe sampling materials for the determination of lead in dust on solid surfaces was evaluated. Criteria for the selection of wipe materials appropriate for field use and subsequent laboratory analysis were identified. These included (a) uniform background lead levels in the materials (preferably < 5 micrograms); (b) ease of digestion in nitric acid/hydrogen peroxide or nitric acid/perchloric acid leachate; (c) > or = 80% recoveries of lead from standard reference material spikes; and (d) ease of use in the field. Other candidate wipe materials that were not examined in this study can be evaluated in a similar manner.
评估了几种市售擦拭采样材料用于测定固体表面灰尘中铅的适用性。确定了适用于现场使用及后续实验室分析的擦拭材料的选择标准。这些标准包括：(a) 材料中背景铅水平均匀（最好<5微克）；(b) 在硝酸/过氧化氢或硝酸/高氯酸浸出液中易于消解；(c) 从标准参考物质加标中铅的回收率≥80%；以及(d) 在现场易于使用。本研究中未检测的其他候选擦拭材料可采用类似方式进行评估。
