Air samples
Airborne fibers determined by Phased Contrast Microscopy (PCM): An air sample is as
collected by pulling air through a filter. The filter catches fibers and is then sent to a laboratory to determine what types of fibers were in the air. Phase contrast microscopy identifies fibers based on size and shape, but not mineral composition. Therefore, the fibers seen by PCM include asbestos fibers as well as other fibers, such as textiles, fiberglass, cellulose, which might be present in your home
