Temuco is one of the five largest cities in Chile with high air pollution. The air of Temuco and from other southern cities of Chile is becoming polluted due mainly to residential wood combustion (RWC). However, the species and quality of the biomass, wood burning devices, and their operation modes have tremendous differences in term of emissions over those other cities where there are huge particulate matter (PM) episodes in winter. Between June and September (winter) of 2011, a study was conducted to evaluate source apportionment of ultrafine particles in Temuco using chemical mass balance receptor modeling and MOUDI sampling. Daily concentrations of PM2.5 were found to be significantly higher than the corresponding EPA air quality standard of 35 μg/m3. For winter-spring 2011, both natural and anthropogenic sources were solved for Temuco where biomass burning and mobile sources were significant sources of ultrafine particles (UFP). The largest percentage of UFP comes from residential biomass combustion. Mobile sources also account for significant emissions that affect the air quality of Temuco. These results will be helpful in combating atmospheric problem in the region. This is an abstract of a paper presented at the 106th AWMA Annual Conference and Exhibition (Chicago, IL 6/25-28/2013).
