摘要: Diesel engine emissions are rich in PAHs and NPAHs, vehicular a major source of NPAHs urban air. Specific including 1-nitropyrene, enriched diesel exhaust relative to other sources have been used as source-specific tracers for exhaust. However, changes engines emission control technology driven by air quality regulations has led substantial reductions PAH NPAH from modern the PAH/NPAH composition these emissions. This chapter examines contribution ambient concentrations personal exposures effect changing treatment technologies on emitted engines.
