Fine-particle pollution associated with winter haze threatens the health of more than 400
million people in the North China Plain. Sulfate is a major component of fine haze particles …

There is a large gap between the simulated and observed sulfate concentrations during
winter haze events in North China. Although multiphase sulfate formation mechanisms have …

Sulfate aerosols exert profound impacts on human and ecosystem health, weather, and
climate, but their formation mechanism remains uncertain. Atmospheric models consistently …

Atmospheric measurements showed rapid sulfate formation during severe haze episodes in
China, with fine particulate matter (PM) consisting of a multi-component mixture that is …

Nitrate and sulfate are two key components of airborne particulate matter (PM). While
multiple formation mechanisms have been proposed for sulfate, current air quality models …

Understanding the mechanism of haze formation is crucial for the development of deliberate
pollution control strategies. Multiphase chemical reactions in aerosol water have been …

Heterogeneous oxidation of sulfur dioxide (SO2) is suggested to be one of the most
important pathways for sulfate formation during extreme haze events in China, yet the exact …

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 …

Particulate sulfate is one of the most important components in the atmosphere. The
observation of rapid sulfate aerosol production during haze events provoked scientific …

Haze events in China megacities involve the rapid oxidation of SO2 to sulfate aerosol. Given
the weak photochemistry that takes place in these optically thick hazes, it has been …
