| Abstract |
Airborne asbestos levels were measured by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and phase constrast microscopy (PCM) before, during and after removal of sprayed-on acoustical plaster from the ceilings of four suburban schools. Air samples were collected at three types of sites: indoor sites with asbestos-containing material (ACM), indoor sites without ACM (indoor control), and sites outside the building (outdoor control). Bulk samples of the ACM were collected prior to the removal and analyzed by polarized light microscopy (PLM). A vigorous quality assurance program was applied to all aspects of the study. Airborne asbestos levels were low before and after removal. Elevated, but still relatively low levels were measured outside the work area during removal. This emphasizes the need for careful containment of the work area. |
