Abstract

Electron paramagnetic resonance (EPR) spectrometry has been used to study diesel particulate matter. The EPR signals for a graphitized carbon black and particles collected from two different diesel engines have been compared. Variations in the line widths and signal intensities due to various chemical and physical pretreatments of the particles were observed. The EPR signals for the diesel particulates were shown to be sensitive to oxygen, nitric oxide, nitrogen dioxide, and ultraviolet and visible radiation. These results suggest that EPR may be a convenient means for characterizing particles from different sources or for demonstrating particle reactivities. The demonstrated photochemical reactivities of the airborne particles have significant environmental health implications.
