Significats de organic aerosol en anglès

The mass spectrum of the unoxidized primary organic aerosol closely resembles ambient hydrocarbon-like organic aerosol (HOA).

Conclusions: A more complete structural characterization of polar organosulfates that originate from isoprene secondary organic aerosol was achieved.

Isoprene significantly contributes to organic aerosol in the southeastern United States where biogenic hydrocarbons mix with anthropogenic emissions.

A laboratory study was conducted to evaluate the potential for secondary organic aerosol formation from emissions from automotive exhaust.

Since atmospheric conditions vary in both space and time, air quality models need to treat primary organic aerosol emissions as semivolatile.

The chemical evolution of the organic aerosol inside the PAM reactor appears to be similar to that observed in the atmosphere.

Secondary organic aerosol (SOA) can affect the atmospheric radiation balance through absorbing light at shorter visible and UV wavelengths.

These results suggest that fragmentation reactions may be key steps in the formation and evolution of oxygenated organic aerosol (OOA).

EG emissions are potentially important because they can lead to the formation of secondary organic aerosol following oxidation in the atmospheric aqueous phase.

Experimental measurements of gas-particle partitioning and organic aerosol mass in diluted diesel and wood combustion exhaust are interpreted using a two-component absorptive-partitioning model.

Of this fraction, a significant subfraction is secondary organic aerosol (SOA), meaning that the compounds are a by-product of chemistry in the atmosphere.

Importantly, this compound accounted for an average of 0.25% and as high as 1% of the total organic aerosol mass during BEARPEX 2009.

We also show that a very rich mixture of organic aerosols is emitted from the sea surface.

It is now known that aqueous phase chemistry is important in the formation of secondary organic aerosols.

Biogenic secondary organic aerosols (SOA) are generally considered to be more abundant in summer than in winter.

Organic aerosol (OA) particles affect climate forcing and human health, but their sources and evolution remain poorly characterized.
