Organic peroxides (POs) are organic molecules with one or more peroxide (− O–O−)
functional groups. POs are commonly regarded as chemically labile termination products …

Several hands are now working worldwide to reduce exposure to air pollution, especially in
develo** nations. Future steps should be determined and classified as possible research …

The formation mechanism of aerosol sulfate during wintertime haze events in China is still
largely unknown. As companions, SO2 and transition metals are mainly emitted from coal …

Many places on earth still suffer from a high level of atmospheric fine particulate matter
(PM2. 5) pollution. Formation of a particulate pollution event or haze episode (HE) involves …

Hydroxyl radical (OH) is a key oxidant that triggers atmospheric oxidation chemistry in both
gas and aqueous phases. The current understanding of its aqueous sources is mainly …

Severe events of wintertime particulate air pollution in Bei**g (winter haze) are associated
with high relative humidity (RH) and fast production of particulate sulfate from the oxidation …

Atmospheric oxidation of sulfur dioxide (SO2) forms sulfate-containing aerosol particles that
impact air quality, climate, and human and ecosystem health. It is well-known that in-cloud …

Emitted by numerous primary sources and formed by secondary sources, atmospheric
brown carbon (BrC) aerosol is chemically complex. As BrC aerosol ages in the atmosphere …

Traditional atmospheric chemistry posits that sulfur dioxide (SO2) can be oxidized to sulfate
(SO42–) through aqueous-phase reactions in clouds and gas-phase oxidation. Despite …

Active chlorine in the atmosphere is poorly constrained and so is its role in the oxidation of
the potent greenhouse gas methane, causing uncertainty in global methane budgets. We …
