Chamber investigations of the fate of diesel emissions in the atmosphere. Volume 1. Task 3, final report

The program quantified the effect of long-term atmospheric exposure of diesel emissions to various types and concentrations of atmospheric pollutants under UV-irradiated and non-irradiated conditions. Examined were the influence of the mode of exhaust injection on the chemical and physical characteristics of the diesel exhaust/air mixture in the chamber, the effect of artifact formation, and the effect of solvent efficiency on the mutagenic activity and chemical composition of organic extracts for a single experiment condition. Experiments were designed to promote the formation of nitrated PAH derivates and more polar compounds. The final report consists of two volumes; Volume I is the final technical report which contains the detailed summary and discussion of work completed during the program.
