FattyĪlcohols are composed of long-chain hydrocarbons and hydroxyl ( −OH) groups, Varying between C 20 and C 34 carbon atoms (Mudge, 2005). Intensity, and local wind speed, likely vary with types and sources ofįAs are known as major components of surface lipids (waxes) with chains Possible emission drivers, such as temperature, light
Possible compounds of PBAPs, however, our knowledge is very limited on theĪbundance, emission mechanisms, and atmospheric behavior of FAs originatedįrom plants. Sugar mannitol as a biotracer) and bacteria (Carslaw et al., 2010). Previous studies estimated globalĮmissions of PBAPs mostly based on the abundance of fungal spores (e.g., the Particles (PBAPs) (Simoneit et al., 2004). In atmospheric aerosols can act as tracers of primary biological aerosol The most prominent chain lengths areĬ 26 to C 30 (Tulloch, 1976). To reduce water loss through evaporation, waxes originating from this source Because the main function of plant waxes is Most fattyĪlcohols occur in biota as waxes covering parts of plants, which are useful for preventing desiccation, protection from bacterial attack, UV screening, and The biota for the synthesis of molecules and other compounds. Terrestrial environment, different organisms contain a variety of long-chainĪlcohols (fatty alcohols FAs) because of the diversity of pathways used by Marine sources of atmospheric aerosols (e.g., Gagosian et al., 1981). Lipids can be effectively used as molecular markers of terrestrial and They originated mostly from plant waxes and could be used as useful tracersįor primary biological aerosol particles. Submicrometer particles in the growing season.
A significant fraction of the SFAs was attributed to the Showed significant correlation with sucrose, which is used as a molecular Pronounced peaks during the growing season at each forest site. Among the identified SFAs, n-nonacosan-10-ol was the most abundantĬompound, followed by n-nonacosan-5-10-diol at both of the forest sites.Ĭoncentrations of the SFAs exhibited distinct seasonal variation, with N-heptacosan-5,10-diol, were identified in atmospheric aerosols for the first In this study, we identified five secondary FAs (SFAs) with C 27 andĬ 29 from aerosol samples collected throughout 1 year at two different deciduous forest sites in Japan.
However, studies on theĬomposition and source of the FAs in atmospheric aerosols are very limited.
Lipids (waxes) and can act as surface-active organic aerosols in theĪtmosphere, influencing chemical reactions, particle lifetimes, and theįormation of cloud droplets and ice nuclei. Fatty alcohols (FAs) are major components of surface
