摘要: Representative PM2.5 and PM10 source emissions were sampled in Texas during the Big Bend Regional Aerosol Visibility Observa (BRAVO) study. Chemical profiles for elements, ions, carbon fractions of 145 samples are reported paved unpaved road dust, soil motor vehicle exhaust, vegetative burning, four coal-fired power stations, an oil refinery catalytic cracker, two cement kilns, residential meat cooking. Several taken from each emitter type, these averaged by subgroups based on commonality chemical composition. The standard deviation represents variability mass fractions. BRAVO differed some respects measured elsewhere. High calcium abundances geological high selenium antimony cracker found. Abundances eight thermally evolved [Atmos. Environ. 28 (15) (1994) 2493] differ among combustion sources, a Monte Carlo simulation demonstrates that differences sufficient to differentiate several carbon-emitters.
