متن کاملThe density of humic acids and humic like substances (HULIS) from fresh and aged wood burning and pollution aerosol particles
Atmospheric aerosols play significant roles in climatic related phenomena. Size, density and shape of particles affect their fluid-dynamic parameters which in turn dictate their transport and lifecycle. Moreover, density and shape are also related to particles’ optical properties, influencing their regional and global radiative effects. In the present study we have measured and compared the eff...
متن کامل5.2 Formation and Transformation of Humic-like Substances (hulis) in Atmospheric Aerosols: Relation to Climate Forcing
Humic-like substances (HULIS) have been identified in the water soluble component of atmospheric aerosols, comprising as much as 50% of the water soluble aerosol species at both urban and rural sites (Cappiello, et al., 2003; Limbeck, et al., 1996). These substances have been found to resemble the aquatic humic and fulvic acids, which are known to play important roles in groundwater chemistry. ...
متن کاملChirality and the origin of atmospheric humic-like substances
Aerosol water extracts and atmospheric humiclike substances (HULIS) obtained from PM2.5-fraction aerosol samples collected in a rural/continental background environment and in an urban environment in spring and summer, and at a tropical site that was heavily impacted by biomass burning were studied. HULIS was obtained as the water-soluble, methanol-elutable material isolated from a solid-phase ...
