Atmospheric HULIS: How humic-like are they? A comprehensive and critical review
A class of organic molecules extracted from atmospheric aerosol particles and isolated from fog and cloud water has been termed HUmic-LIke Substances (HULIS) due to a certain resemblance to terrestrial and aquatic humic and fulvic acids. In light of the interest that this class of atmospheric compounds currently attracts, we comprehensively review HULIS properties, as well as laboratory and fie...

متن کاملSurfactant properties of atmospheric and model humic-like substances (HULIS)
[1] Surface-active organics such as humic-like substances (HULIS) are abundant in aerosol particles and can lower the surface tension of cloud droplets forming on secondary organic and biomass burning aerosols. How fast is the diffusion of these species, relative to the time scale of cloud droplet growth? Here we report surface tension measurements of solutions containing HULIS extracted from s...
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 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...
