Description:
Water is collected in a polyethylene or glass container and shipped to the laboratory. nown aliquots of the sample are filtered through a 0.1 to 0.22 um pore mixed cellulose ester (MCE). arbon extraction replica is prepared from a portion of the filter and is examined in the TEM at a magnification of 10,000 to 20,000X. sbestos structures are identified by, morphology, selected area electron diffraction (SAED) and energy dispersive x-ray analysis (EDXA). tructures are classified according to the counting rules specified in the Chatfield polycarbonate filter protocol (1). nly asbestos structures greater than 10 Am in length are counted.
