Asbestos identification is detennined by the morphology, visual Selected Area Electron Blemental Analysis using an Energy Dispersive X-ray Analyzer (EDAX). ter is calculated by taking (he number of asbestos structures and dividing by the arer analyzed. Air concentration is calculated by muldplying the effective filter arca (EPA) by the filter concentration and then dividing by the volume of air collected in cubic centimeters (cc). The data pertaining ts these calculations can be found on the Asbestos Count Sheet.
