The Robbins Particulate Study (RPS) from October, 1995 through September, 1996 characterized PM2.5 and PM10 mass, chemical concentrations, and source contributions at four sites in neighborhoods surrounding the Robbins Waste-to-Energy (WTE) facility, southwest of Chicago, IL. The design of the measurement program and methodology of analyses are described in a previous paper. PM2.5 data were obtained from the fine-particle filter of dichotomous samplers, rather than samplers intended to provide federal reference method (FRM) sampling. No exceedances of the 24-hour-average National Ambient Air Quality Standard (NAAQS) for PM10 of 150 {micro}g/m{sup 3} were found at any of the four sites; the maximum concentration was 61.7 {micro}g/m{sup 3}. Annual-average PM10 concentrations were similar at the four measurement locations, ranging from 24.7 to 27.4 {micro}g/m{sup 3}. These values are approximately half of the annual-average PM10 NAAQS of 50 {micro}g/m{sup 3}. The highest PM2.5 mass concentration of 32.2 {micro}g/m{sup 3} was less than PM2.5 standard of 65 {micro}g/m{sup 3}. The annual-average PM2.5 at one site was 15.2 {micro}g/m{sup 3}, slightly exceeding the three-year annual PM2.5 standard of 15 {micro}g/m{sup 3}, but the spatial average at the four sites was less than 15 {micro}g/m{sup 3}. Annual-average PM10 source contributions determined by a Chemical Mass Balance on half of the samples were: (1) geological (20% to 23%); (2) secondary sulfate (24% to 25%); (3) secondary nitrate (17% to 20%); (4) motor vehicle exhaust (18% to 20%); (5) steel production (4% to 6%); (6) road salt (3% to 7%); (7) residential wood combustion (3% to 5%); and (8) coal combustion ({approximately} 1.5%). Large contributors to trace metal concentrations (such as copper, zinc, lead, cadmium, and zirconium) were minor contributors to PM2.5 and PM10. Sources of the trace metals were not quantified by CMB owing to lack of industry-specific source profiles.
