An Improved Fluorometric Method of Analysis for Benzo(a)pyrene in.Airborne Participates

This report describes the research employed to improve the tentative fluorometric method recommended by the American Public Health Association for the determination of benzo(a)pyrene in airborne particulars. A number of variables which affected the accuracy and precision of the tentative method were investigated. Five major improvements are suggested as a result of this research. The relative standard deviation of the improved method varied between 3.5% and 6.2% for benzo(a)pyrene levels of 15 to 400 nanograms.
