NOTE: The lower limit of detection for 100 microscope fields counted per sample is equal to .002 fibers/cc, greater than 5 um in length for an 8 hour period, and based upon the effective filter area, and the microscope counting area.
* ----- denotes street dirt collected and examined at the location and day while samples of the ambient air were being collected. The dirt was examined for proof of fallen asbestos fibers by phase contrast microscopy. All dirt samples showed evidence of asbestos fibers.
