Contents Notes
"Two analytical methods and two sampling techniques were evaluated for their effectiveness in a project to remove air-entrainable asbestos from the Corvallis Environmental Research Laboratory in Corvallis, Oregon. The two analytical methods were phase contrast microscopy (PCM) and transmission electron microscopy (TEM). The sampling techniques included a static (nonaggressive) method and an aggressive one using a blower. Air sampling was conducted at an EPA office building that had undergone an amosite asbestos abatement program. The aggressive sampling technique revealed that air-entrainable asbestos remained in work areas after completion of abatement actions. Results also confirm that under similar sampling conditions, TEM analysis detects more fibers than PCM because of the former's better resolving capability. Because PCM does not discriminate between asbestos and other fibers and cannot resolve fibers thinner than about 0.2 [micro]m, this method may not accurately reflect the true hazard potential. TEM coupled with aggressive sampling should be recommended as the analytical method of choice for final post-abatement clearance testing."
