Analysis using au Energy Dispersive X-ray Analyzer (EDAX). Iter is calculated by taking the mimbec of asbestos structures and dividing by the area analyzed. Air concentration is calculated by multiplying 2 (EEA; by the filter concentration and then dividing by the volume of air collected in cubic centimeters (cc). e calculations can be found on the Ashestos Count Sheet.
