Organic, elemental, and isotopic tracers of air pollution sources in Albuquerque, NM
Abstract To explore the use of organic compounds as tracers for air pollution sources, data for radiocarbon, trace elements, carbon, and low-polarity organic compounds were obtained for Albuquerque, NM, in December 1985. Measurement of radiocarbon in the organic fraction permitted unambiguous discrimination of modern carbon (wood burning) and fossil carbon (motor vehicle emissions). Modern and fossil carbon co-varied at night, but during the day, modern carbon was correlated with retene, a proposed tracer for softwood combustion. Similar diurnal differences were observed in a multiple linear regression of elemental tracers of woodsmoke and motor vehicle emissions. Using a physical adsorption model, the gas particle distribution of semi-volatile organic compounds in the samples was estimated. The results suggest that, for some compounds, distribution between the gas and particle phases may act as a third “source” affecting measured particulate concentrations. Supporting this conclusion, a factor analysis of the daytime data gave three factors associated with woodsmoke, motor vehicles, and volatile species, respectively.
