A program designed to reveal factors influencing the diurnal variation and geographical distribution of airborne particulate mutagenicity in the South Coast Air Basin (SCAB) and to establish current 'baseline' levels for this mutagenicity was conducted using the Ames Salmonella/mammalian microsome assay. Ambient particles were collected simultaneously at several sites across the SCAB using collection periods shorter than the standard 24 hours. Collections were made every 12 hours for a 72-hour period in winter 1980, and every three hours for a 24-hour period in late summer 1980 and early spring 1981.
