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 acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning
of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In addition …

Soluble transition metals in particulate matter (PM) can generate reactive oxygen species in
vivo by redox cycling, leading to oxidative stress and adverse health effects. Most metals …

Aerosol acidity plays a key role in secondary aerosol formation. The high-temporal-
resolution PM 2.5 pH and size-resolved aerosol pH in Bei**g were calculated with …

Acidity is an important property of particulate matter (PM) in the atmosphere, but its
association with PM toxicity remains unclear. Here, this study quantitively reports the effect of …

Atmospheric deposition is a source of potentially bioavailable iron (Fe) and thus can partially
control biological productivity in large parts of the ocean. However, the explanation of …

It has long been hypothesized that acids formed from anthropogenic pollutants and natural
emissions dissolve iron (Fe) in airborne particles, enhancing the supply of bioavailable Fe to …

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

Mineral dust is a complex entity containing a range of iron minerals including poorly
crystalline to crystalline iron oxides to clay minerals. Important progress has been made to …

This paper reviews our knowledge of the measurement and modeling of mineral dust
emissions to the atmosphere, its transport and deposition to the ocean, the release of iron …
