Abstract
Guidelines for the collection and analysis of environmental lead (7439921) samples were presented. Tools, techniques, and safety procedures used for the collection of dried paint, soil, surface dust, and workplace air for lead analysis were specifically discussed. The suggested method of extraction of the lead from collected samples using nitric-acid and hydrogen-peroxide at high temperatures (on a hot plate or in a microwave oven) was described. The American Society for Testing and Materials method E-1613, which involved the use of flame atomic absorption spectrophotometry (FAAS), graphite furnace atomic absorption spectrophotometry, or inductively coupled plasma atomic emission spectrometry (ICP-AES) was recommended for the determination of solubilized lead. The accuracy of these procedures was assessed using a subset of data from the Environmental Lead Proficiency Analytical Testing program. Statistical analysis demonstrated that, in general, the effects of sample preparation technique (hot plate versus microwave oven during extraction) and of analytical method (FAAS versus ICP-AES) were insignificant. Further analysis of slight differences seen between analytical techniques demonstrated that FAAS yielded higher mean values than ICP-AES for analysis of dust loaded filter samples; this difference was not significant in soil samples, and was dependent on the lead concentration in paint samples.
