This thesis has investigated the cascade impactor with its fractionating particulate capabilities for monitoring respirable particulate matter. Additionally, the cascade impactor was compared with the high volume sampler, the present acceptable method of measuring total suspended particulates.This two-year study analyzed the quarterly and annual geometric means, geometric standard deviations and mass median diameters of the cascade impactor concentrations. Correlation coefficients between the cascade impactor and high volume sampler were analyzed to reveal the relationship between the two sampling methods.
