In order to evaluate the impact of emission from heavy-duty diesel engines on the mutagenicity of ambient air, this study was designed to compare the mutagenic activity of size-fractionated airborne particles collected inside and outside a large bus terminal. Most diesel exhaust studies have been performed in a laboratory setting. The NYC Port Authority Bus Terminal Study, on the other hand, was designed to collect, measure, chemically characterize, and bioassay diesel exhaust as it exists after becoming resident in the surrounding air. Chamber studies have demonstrated that some of the organic compounds associated with diesel exhaust undergo atmospheric transformation when subjected to ultraviolet light in combination with other pollutants such as ozone, nitrogen dioxide, and reactive hydrocarbons. These studies have also shown that the mutagenic response changes with the transformations. A high ambient loading of the emissions aerosol was chosen for the study in order to maximize the amount of information which could be acquired on the character, ambient exposure level, and potential health effects associated with diesel exhaust.
