摘要: Black carbon (BC), an important component of the atmospheric aerosol, has climatic, environmental, and human health significance. In this study, BC was continuously measured using a two-wavelength aethalometer (370 nm 880 nm) in Rochester, New York, from January 2007 to December 2010. The monitoring site is adjacent two major urban highways (I-490 I-590), where 14% 21% total traffic heavy-duty diesel vehicles. annual average concentrations were 0.76 μg/m3, 0.67 0.60 0.52 μg/m3 2007, 2008, 2009, 2010, respectively. Positive matrix factorization (PMF) modeling performed PM2.5 elements, sulfate, nitrate, ammonia, elemental (EC), organic (OC) data U.S. Environmental Protection Agency (EPA) speciation network Delta-C (UVBC370nm – BC880nm) data. been previously shown be tracer wood combustion factor. It used as input variable source apportionment models for first time study...
