“…The 24-h-averaged concentrations of succinic, glutaric, and adipic acids each range from 0.2 to 0.5 pg m-3 in Los Angeles (11), although higher daytime values of 1.2 pg m-3 for glutaric acid and 1.6 pg m-3 for adipic acid have also been reported (12). Glutaric acid has been detected in rural areas of the Ohio River valley at concentrations of 0.002-0.05 pg m-3 (13).…”

“…In contrast, relatively little information is available about organic acids in aerosol particles (Schuetzle et al, 1973; Grosjean et al, 1978;van Vaeck and van Cauwenberghe, 1985), although these acids can form an important part of the ether-extractable fraction (Ketseridis et al, 1976; Hahn, 1980) as well as of the total acidity (Ferek et al, 1983) of aerosol particles.…”

“…Occurrence of these acids has been observed, especially during photochemical or particulate smog episodes (Schuetzle et al, 1973;Grosjean et al, 1978). Different studies have shown several possible chemical formation mechanisms, such as reactions of H 0 2 radicals with aldehydes, Criegee intermediates with H 2 0 vapour (Calvert et al, 1985), or photochemical reactions of hydrocarbons, NO,, ozone, and free radicals (Grosjean et al, 1978).…”

During fall and winter 1986/87, aerosol samples were collected with a 5-stage impactor in an urban, a suburban, and a rural area in Central Europe. The weak acid content of aerosol particles was characterized by buffer capacity titrations, and organic acids were determined by HPLC. C 4 -C 6 dicarboxylic acids were found to be the main constituents of aerosol organic acids, with the highest concentrations occurring during a winter-time smog period. Size distributions of single species showed a maximum in the accumulation mode, indicating that these compounds have gaseous precursors. It is suggested that these precursors are of anthropogenic origin.

“…However, it carries with it some of the same problems described above for GC/MS in terms of extraction and elution of polar compounds. Finally, one of the first sets of studies on organic aerosols utilized direct injection of material into a highresolution mass spectrometer [Schuetzle, 1972;Cronn, 1975]. The absence of the GC step removes the problems associated with extraction and elution of material from the column.…”

Abstract. Atmospheric aerosol particles are known to contain organic carbon material in variable amounts, depending on their location. In some parts of the world, organic compounds make up the majority of the total suspended particle mass. This class of particulate matter is important in a wide range of geophysical and environmental problems, ranging from local issues (e.g., pollution toxicity) to the global scale (e.g., climate change). Unfortunately, the richness of organic chemistry and the highly variable physical properties associated with both natural and anthropogenic organic particles lead to great difficulties in sampling and obtaining complete chemical information on these materials. These obstacles result in an incomplete picture of a potentially significant part of atmospheric chemistry and a correspondingly poor understanding of the geophysical and environmental effects of this aerosol. Given the paucity of quantitative molecular data, the purpose of this paper is not to quantitatively describe the importance of organic aerosols in environmental issues, but rather to present a basis for defining what data are needed. With this goal in mind, we begin with an overview of the major environmental issues known to be affected by organic aerosols, followed by a description of the distribution, sources, and chemical and physical properties of organic aerosols as they are currently understood. Methods used to collect and study organic aerosols are provided, followed by a list of outstanding scientific questions and suggestions for future research priorities. mental Protection Agency (U.S. EPA), 1996]. This fraction has been studied extensively, and several models of the geographical distribution and climatic effects of this group of compounds in the aerosol have appeared [IPCC, 1995]. While somewhat less studied, the insoluble inorganic fraction has been analyzed, for example, with nuclear methods, and generally consists of metal oxides, silicates, and clay minerals derived from soil dust. Unlike the salt and soil dust fractions, the organic compounds cover a very wide range of molecular forms, solubilities, reactivities, and physical properties, which makes a complete characterization extremely difficult. The so-called "elemental" carbon (EC) aerosol has been studied extensively, but it is still not clear to what degree it is indeed elemental [graphitic, C(0)] material or high molecular weight refractory organic species or a combination of both. Consequently, there is still no complete inventory of the chemical compounds that compose the fine-particle organic aerosol from any site in the world, and there is only a limited understanding of the sources, sinks, transport, and transformation processes of these particles and their effects. Since organic compounds are usually the second most abundant component of fine aerosol after sulfates [Heintzenberg, 1989; White, 1990; U.S. EPA, 1996], our understanding of the numerous
