In Chile, the State Public Health Office (Ministerio de Salud Publica) is responsible for pollution control and for air quality. This office has been monitoring only toxic gases and total suspended particulate matter. The present work is the first study in Chile designed to determine trace elements and their concentrations in particulate matter in the air. By use of enrichment factors, 25 trace elements were classified according to natural or anthropogenic origin. There were two sampling periods: July (winter) and September (spring) 1976. Four sites were studied, located about 6 km north, south, west and east of downtown Santiago. The south, north and west sites are urban and 55 m above sea level. The east site is suburban and approximately 270 m higher than the others. Twenty-four-hour samples were collected on Whatman-41 cellulose filter paper, in a modified stainless steel Buchner funnel. Approximately 10 m/sup 3/ were used at the urban sites and 200 m/sup 3/ at the suburban site. Instrumental neutron activation analysis (INAA) was used as the analytical technique.
