Continuous monitoring of metals (Mg, Al, Cu, Zn, Ni, Ti, Fe), nitrate, ammonium, and sulfate in airborne particles sampled on the eastern fringe of Los Angeles was carried out throughout the summer of 1999. High-volume air samplers were used to collect particulate matter along a high-traffic corridor in which sampling sites were less than one mile apart. Inductively coupled plasma- atomic emission spectrometry was used to analyze the metals of interest while ion chromatography was used to measure nitrate, ammonium, and sulfate.
