“…Therefore, the observed link between MAE and f 60 /f 44 shows that the strength of BrC absorption is linked to the emissions of the f 60 -related organics, and ranges from 0.25 m 2 g −1 to 1.5 m 2 g −1 (which compares well to measurements from other studies -0.5 m 2 g −1 to 2.9 m 2 g −1 , Hoffer et al, 2006;Yang et al, 2009;Kirchstetter et al, 2004). Some studies show low-visible and UV absorption of POM from BB being linked to nitrated levoglucosan-based compounds Kitanovski et al, 2012). Our data cannot differentiate between inorganic and organic nitrates, however these compounds remain a possibility as the contributors to BrC absorption.…”

Traditional gas and particle phase chemical markers used to identify the presence of biomass burning (BB) emissions were measured for a large forest fire near Boulder, Colorado. Correlation of the organic matter mass spectroscopic m/z 60 with measured particle light absorption properties found no link at 532 nm, and a strong correlation at 404 nm. Non-black carbon absorption at 404 nm was well correlated to the ratio of the mass fractions of particulate organic matter (POM) that was m/z 60 (f₆₀) to m/z 44 (f₄₄). The f₆₀ to f₄₄ ratio did not fully explain the variability in non-BC absorption, due to contributions of brown carbon (BrC) absorption and absorption due to internal mixing of POM with black carbon (BC). The absorption Ångstrom exponent (Å_Abs) showed a good correlation to f₆₀/f₄₄; however the best correlation resulted from the mass absorption efficiency (MAE) of BrC at 404 nm (MAE_{POM-404 nm}) and f₆₀/f₄₄. This result indicates that the absorption of POM at low visible and UV wavelengths is linked to emissions of organic matter that contribute to the m/z 60 mass fragment, although they do not contribute to 532 nm absorption. m/z 60 is often attributed to levoglucosan and related compounds. The linear relationship between MAE_{POM-404 nm} and f₆₀/f₄₄ suggests that the strength of BrC absorption for this fire can be predicted by emissions of f₆₀-related organic matter

Abstract. Filter samples of fine particulate matters were collected at four sites in northern China (urban, rural, and mountain) in summer and winter, and the contents of nine nitrated phenols were quantified in the laboratory with the use of ultra-high-performance liquid chromatography coupled with mass spectrometry. During the sampling periods, the concentrations of particulate nitrated phenols exhibited distinct temporal and spatial variation. On average, the total concentration of particulate nitrated phenols in urban Jinan in the wintertime reached 48.4 ng m −3 , and those in the summertime were 9.8, 5.7, 5.9, and 2.5 ng m −3 in urban Jinan, rural Yucheng and Wangdu, and Mt. Tai, respectively. The elevated concentrations of nitrated phenols in wintertime and in urban areas demonstrate the apparent influences of anthropogenic sources. The positive matrix factorization receptor model was then applied to determine the origins of particulate nitrated phenols in northern China. The five major source factors were traffic, coal combustion, biomass burning, secondary formation, and aged coal combustion plume. Among them, coal combustion played a vital role, especially at the urban site in the wintertime, with a contribution of around 55 %. In the summertime, the observed nitrated phenols were highly influenced by aged coal combustion plumes at all of the sampling sites. Meanwhile, in remote areas, contributions from secondary formation were significant. Further correlation analysis indicates that nitrosalicylic acids were produced mostly from secondary formation that was dominated by NO 2 nitration.
