Estimation of atmospheric emissions of six semivolatile polycyclic aromatic hydrocarbons in southern canada and the United States by use of an emissions processing system.

摘要: Polycyclic aromatic hydrocarbons (PAHs) are toxic compounds that ubiquitous in the atmospheric environ ment. The input for an emissions processing system was originally configured study of criteria air pollutants updated to calculate six semivolatile PAHs. goal work produce estimates with spatial and temporal resolution needed serve as a regional quality model southern Canada U.S. Such modeling is helpful determining reductions PAH may be necessary protect human ecosystem health. total annual emission PAHs (Σ6PAH) both countries estimated at 18 273 Mg/year. A 90% these arise from sources. top source types account 73% related metal production, open burning, incineration, forest fires. factors used this were derived published compilations. Although approach has ad...
