Air samples
Airborne fibers as determined by Phased Contrast Microscopy (PCM): An air sample is 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. By counting all fibers, we are being more protective of your health when we compare this to our screening value for asbestos fibers.

**Screening Value - The NYC standard for asbestos in community and residential buildings is 0.01 fibers/cubic centimeter (f/cc) in indoor air. This standard is used for re-occupancy in an indoor area where asbestos was detected and removed.
