Airborne asbestos levels were measured by transmission electron microscopy (TEM) before, during and after encapsulation of asbestos-containing material with latex paint in a suburban junior high school. The ceilings of the school were covered with a sprayed-on material containing chrysotile asbestos. Air samples were collected at four types of sites: indoor sites with unpainted asbestos material scheduled for painting, indoor sites with asbestos material which had been painted 16 months prior to the study, indoor sites with no asbestos material, and outdoor sites on the roof of the building. Bulk samples were collected prior to painting and analyzed by polarized light microscopy (PLM) to characterize the asbestos-containing material.
