| Understanding particulate air pollution in the Los Angeles Basin requires characterization of its concentration and composition. Particulate air pollution causes increased morbidity and mortality in healthy and ailing persons. Knowledge of the composition and concentration of the particulate matter provides insights into the sources of air pollution as well as the potential health effects. In this study, we use a novel instrument, the Particle-Into-Liquid Sampler inline with two ion chromatographs, to measure the concentration of inorganic and organic particulate air pollutants in the ambient atmosphere in Claremont, CA. Previous studies of inorganic particulate air pollution at this site revealed charge balance discrepancies that may be explained by studying organic particulates, specifically carboxylic acids. The pollution data will also be correlated to weather patterns recorded with a weather station mounted onsite, giving further insight into sources and behavior of aerosols in the basin. |
