PM2.5 emission elemental composition.
A field study was carried out from 2003 to 2004 with the aim to develop the PM2.5 emission source profiles from light duty gasoline and heavy-duty diesel vehicles, as well as emission source profiles from waste incineration, wood burning and meatbroiling. Over 25 chemical species were quantified from the fine particles emitted by the different combustion sources investigated, including organic and elemental carbon, ions and elements. The OC/TC ratio found in the different PM2.5 profiles was dissimilar as well as the sulfate, nitrate, ammonium, soil species and trace element content. Consequently these combustion emission profiles could be used in source reconciliation studies for fine particles.A field study was carried out from 2003 to 2004 with the aim to develop the PM2.5 emission source profiles from light-duty gasoline and heavy-duty diesel vehicles, as well as emission source profiles from waste incineration, wood burning, LP gas combustion, and meat broiling.
