Soot in urban atmospheres: determination by an optical absorption technique
Journal Article
·
· Science; (United States)
Technical report: The application of a new analytical metal to determine the concentrations of particulate carbonaceous emissions (soot) in the carbonaceous aerosol load of urban atmospheres is described. The optical absorption technique is capable of determining the soot content of ambient air samples under different atmospheric conditions and over a wide geographical area. Analyses of data indicate that soot concentrations compose a major fraction of carbonaceous aerosols in the atmosphere. The carbon loadings determined in air samples collected at several U.S. locations are discussed. (6 graphs, 15 references)
