Chemical and physical characteristics of organic fractions in airborne particulate matter

Abstract

Organic constituents in airborne particulate matter were recovered by benzene extraction of hi-vol sample filters located adjacent to a major highway intersection in New York City.

Analysis of carbonaceous materials in southern California atmospheric aerosols

“…Based in part on the work of Cukor et al (5), we believed that primary organic particulate matter in urban areas has as its principal source partially oxidized lubricating oils. To further demonstrate this, a comparison was made of the cyclohexane soluble organics in atmospheric particles collected at 12 locations throughout California with cyclohexane extracts from automobile exhaust particulate matter.…”

“…Even the proportion of the elemental carbon present remains a matter of speculation. Previous studies of carbonaceous matter have primarily examined organic solvent-soluble fractions and include the work of Mader et al (2), Dubois et al (3), Ciaccio et al (4), and Cukor et al (5). The latter group analyzed solvent extracts from suspended particulate matter collected near a major intersection in New York City.…”

Composition of organic constituents in breathable airborne particulate matter near a highway

“…It indeed would be informative from the viewpoint of environmental health to realize the variation of distribution of organic substances as a function of aerodynamic size, particularly of the breathable size range as compared to the total collectable airborne particulate matter (2). The importance of oxygenated organic substances acting as cocarcinogens and carcinogens has been given and their possible presence in particulate matter was particularly observed (1,3,4).…”

Organic Compounds in Urban Atmospheres: A Review of Distribution, Collection and Analysis

“…368 Some physical and chemical characteristics of organic fractions in airborne particulate matter were determined. 369 Silica gel LC was used to separate the extract into hexane-benzene (34%), chloroform (46%) and isopropanol (20%) soluble fractions. High speed LC with a reaction detector of cerium (IV) sulfate, which is reactive to phenols has been described.…”
