Asbestos in dust as determined by TEM analysis: TEM analysis was conducted on all dust samples that showed asbestos content by PLM as less than 1% (if sufficient quantities were available). TEM analysis is very specific, can detect smaller fibers of asbestos, and is subject to less interference. This analysis was done to confirm the PLM findings of no asbestos found. TEM analysis is not used for regulatory purposes for dust samples.
