Soot in Urban Atmospheres: Determination by an Optical Absorption Technique
Abstract
We have used the high optical absorptivity of urban and source particulates to trace their ``graphitic'' component. The optical absorptivity and the particulate carbon loading show a strong correlation. Analyses of the data indicate that primary soot emissions compose a major fraction of the carbonaceous aerosol and put a low limit on secondary organic material produced in correlation with the ozone concentration.
