Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

A key Earth system science question is the role of atmospheric deposition in supplying vital
nutrients to the phytoplankton that form the base of marine food webs. Industrial and …

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 major cities that witnessed heavy air pollution by nitrogen dioxide (NO 2) and
particulate matter (PM) have experienced a high rate of infection and severity of the …

Increasing Asian dust fluxes, associated with late Cenozoic cooling and intensified
glaciations, are conventionally thought to drive iron fertilization of phytoplankton productivity …

Aerosol acidity plays an important role in atmospheric chemistry. China emits large amounts
of SO2, NOx, and NH3 into the atmosphere, but aerosol acidity is poorly characterized. In …

Aerosol acidity largely regulates the chemistry of atmospheric particles, and resolving the
drivers of aerosol pH is key to understanding their environmental effects. We find that an …

A large fraction of secondary aerosol particles are liquid–liquid phase-separated with an
organic shell and an inorganic core. This has the potential to regulate the hygroscopicity of …

Despite increasing alarms over the health impacts of microplastics (MPs) due to their
detection in human organs and feces, precise exposure evaluations remain scarce. To …

Aerosols supply bioaccessible iron to marine biota which could affect climate through
biogeochemical feedbacks. This paper review progresses in research on pyrogenic aerosol …
