Water-soluble organics in atmospheric particles: A critical review of the literature and application of thermodynamics to identify candidate compounds

Although organic compounds typically constitute a substantial fraction of the fine particulate matter (PM) in the atmosphere, their molecular composition remains poorly characterized. This is largely because atmospheric particles contain a myriad of diverse organic compounds, not all of which extract in a single solvent or elute through a gas chromatograph; therefore, a substantial portion typically remains unanalyzed. Most often the chemical analysis is performed on a fraction that extracts in organic solvents such as benzene, ether or hexane; consequently, information on the molecular composition of the water-soluble fraction is particularly sparse and incomplete.This paper investigates theoretically the characteristics of the water-soluble fraction by splicing together various strands of information from the literature. We identify specific compounds that are likely to contribute to the water-soluble fraction by juxtaposing observations regarding the extraction characteristics and the molecular composition of atmospheric particulate organics with compound-specific solubility and condensibility for a wide variety of organics. The results show that water-soluble organics, which constitute a substantial fraction of the total organic mass, include C2 to C7 multifunctional compounds (e.g., diacids, polyols, amino acids). The importance of diacids is already recognized; our results provide an impetus for new experiments to establish the atmospheric concentrations and sources of polyols, amino acids and other oxygenated multifunctional compounds.

“…VOA are frequently associated with wastewater treatment plants (Kawamura et al 1985;Anselme et al 1985) and are contained in large concentrations in digested biosolids (Howgrave et al 1991;Rains et al 1973) and raw manures (Hoshika 1982;Zahn et al 1997). Freshly composted sewage sludge may contain high levels of organic acids, primarily acetic acid, that inhibit plant growth (Devleeschauwer et al 1981).…”

Samples of active and cured compost from across the U.S. are examined for volatile organic acids (VOA) in relation to other microbiological and chemical properties. VOA are considered important because they reflect temporal microbiological properties of active and cured compost that influence the potential for compost to become odorous and phytotoxic. Data collected from 712 compost samples reveals a wide range of concentration for VOA between 75 and 51,474 ppm (dry basis) with a mean concentration of 4,385 ppm. To understand the variability of VOA, technology and site-specific testing data are needed. The results underscore concern for phytotoxicity and odor release potential, as 15 percent of samples exceeded 10,000 ppm and 2.5 percent exceeded 25,000 ppm VOA. Data and methodologies presented are viewed as useful to better understand relationships between compost biological activities and production of malodorous and phytotoxic VOA.
