Comparison of Wet Wipe vs Micro-Vacuum Sampling Techniques for Determining Concentrations of Asbestos in Surface Dust

The objective of the study was to evaluate the detection efficiency of micro-vacuum surface sampling and surface wet wipe sampling in homes that had been identified with vermiculite attic insulation and/or other asbestos containing materials. Surface samples were collected pre and post weatherization activities and analyzed by transmission electron… CONTINUE READING
