Comprehensive Abatement Performance Pilot Study. Volume 1. Results of Lead DataAnalysis

摘要

This report presents the results from the pilot study that preceded theComprehensive Abatement Performance Study. The major finding of the pilot was the difference between wipe and vacuum methods for collecting dust. The choice of method had a noticeable impact on the level of lead associated with the collected sample. An interlaboratory comparison of dust and soil samples indicated no systematic difference in lead levels between the two laboratories. In addition, intra-laboratory comparisons of sample results by inductively coupled plasma-atomic absorption spectrometry (ICP) and the more sensitive graphite furnace atomic absorption spectrometry (GFAA) indicated good agreement within the common domain of instrument detection limits. Other important findings from the pilot study were results related to variance components.
