Abstract
Several commercially available wipe materials that are used for sampling surface dust for lead (7439921) on hard surfaces were evaluated. The materials tested included filter paper, gauze pads, hand wipes, and baby wipes. A measured amount of standard reference material (SRM) was added to the weighing paper and then transferred to the wipe material. The paper was weighed again to account for the SRM left behind. SRMs used include lead based paint, urban dust and river sediment. Spiked wipes were digested by two different procedures: a nitric-acid/perchloric-acid hot plate extraction, and a nitric-acid/hydrogen-peroxide hotplate extraction. Criteria were established for selecting wipe materials which would be appropriate for field use and subsequent laboratory analysis. These criteria included: uniform background lead levels in the materials, ease of digestion in nitric-acid/hydrogen-peroxide or nitric-acid/perchloric- acid leachate, greater than 80% recoveries of lead from the SRM spikes, and the ease of using the material in the field.
