Laboratory Evaluation of Dust and Dust Lead Recoveries for Samplers and Vacuum211 Cleaners. Volume 2: Appendices from the Quality Assurance Project Plan

摘要

This project was undertaken by the EPA Office of Pollution Prevention and Toxics211u001e(OPPT) to evaluate house dust sampling methods and to assess the efficacy of 211u001etypical household vacuuming on removing leaded dust from residential surfaces. 211u001eDust-lead sampling results from the National Survey of Lead-Based Paint in 211u001eHousing (HUD National Survey) are reexamined, based on new information collected 211u001ein this study about the performance of the dust sampler used during that survey. 211u001eTwo standardized laboratory testing procedures were developed for this study. The 211u001efirst procedure was designed to characterize the performance of house dust 211u001esamplers. The second was designed to evaluate how well commercially available 211u001evacuum cleaners collect dust from various surface types. Three vacuum sampling 211u001emethods and one wipe sampling method were tested by the first procedure.
