Pathways of PFOA to the Arctic: variabilities and contributions of oceanic currents and atmospheric transport and chemistry sources
PFOA the Arctic oceanic currents atmospheric transport chemistry sources
2010/10/21
Perfluorooctanoic acid (PFOA) and other perfluorinated compounds are industrial chemicals in use for decades which resist degradation in the environment and seem to accumulate in polar regions. Transp...
Quantifying atmospheric nitrate formation pathways based on a global model of the oxygen isotopic composition (Δ17O) of atmospheric nitrate
Quantifying atmospheric nitrate formation pathways oxygen isotopic composition atmospheric nitrate
2009/8/7
The oxygen isotopic composition (Δ17O) of atmospheric nitrate is a function of the relative abundance of atmospheric oxidants (O3, ROx=OH+HO2+RO2) and the formation pathway of nitrate from its precurs...
Laboratory studies of ice formation pathways from ammonium sulfate particles
ice formation pathways ammonium sulfate particles
2009/3/13
Cirrus clouds are composed of ice particles and their formation pathways have been studied extensively in the laboratory. The ability of ammonium sulfate particles to act as nuclei for cirrus clouds h...

Phenols are a major class of volatile organic compounds (VOC) whose reaction within, and partitioning between, the gas and liquid phases affects their lifetime within the atmosphere, the local oxidisi...
The relative importance of competing pathways for the formation of high-molecular-weight peroxides in the ozonolysis of organic aerosol particles
competing pathways high-molecular-weight peroxides ozonolysis organic aerosol particles
2009/1/16
High-molecular-weight (HMW) organic compounds are an important component of atmospheric particles, although their origins, possibly including in situ formation pathways, remain incompletely understood...

Global modeling of secondary organic aerosol formation from aromatic hydrocarbons: high- vs. low-yield pathways
secondary organic aerosol aromatic hydrocarbons high- vs. low-yield pathways
2008/11/6
Formation of SOA from the aromatic species toluene, xylene, and, for the first time, benzene, is added to a global chemical transport model. A simple mechanism is presented that accounts for competiti...
