Sources and Emission Factors of Polycyclic Aromatic Hydrocarbons

摘要

The anthropological sources for polycyclic aromatic hydrocarbons and their emission factors are discussed. The major sources are divided into two categories: Stationary sources and mobile sources. The limitations and weaknesses of the emission factors are pointed out to be limited data from each source, different sampling methods, and methods for PAH analysis. The total annual emissions in USA are calculated.
