An Investigation of Filter Types,Extraction Solvents and Storage Conditions Used for PAH Measurement in Diesel Exhaust

Abstract

A device capable of collecting simultaneously eight equivalent particulate diesel exhaust samples was constructed to test the effect of filter type, extraction solvent and storage condition on the measured concentration of five PAH compounds (fluoranthene-Ft, pyrene-Py, benz(a)anthracene-BaA, benzo(k)fluoranthene-BkFT, and benzo(a)pyrene-BaP) in diesel exhaust. An experimental design was used to most efficiently test the variables. A linear model (GLM) was used to analyze the data.
