Stable Sulfur Isotopes Revealed a Major Role of Transition-Metal-Ion Catalyzed SO2 Oxidation in Haze Episodes.

Environmental Science and Technology, 2020
Secondary sulfate aerosols played an important role in aerosol formation and aging processes, especially during haze episodes in China. Secondary sulfate was formed via atmospheric oxidation of SO2 by OH, O3, H2O2 and transition metal catalyzed (TMI) O2.

Sulfur Isotopes in Biogenically and Abiogenically Derived Uranium Roll-Front Deposits

Economic Geology, 2019
Ore assemblages in uranium roll-front deposits are highly variable and heavily dependent on Eh/pH conditions. Sulfur isotopes in pyrite traditionally have been employed to distinguish between biogenic or abiogenic redox pathways as drivers of roll-front ...

Signature of oxygen and sulfur isotopes of sulfate in ground and surface water reflecting enhanced sulfide oxidation in mine areas

Applied Geochemistry, 2019
Aqueous geochemistry data together with sulfur and oxygen isotope ratios of minerals and dissolved sulfate in ground and surface water were assessed in six mining areas including five metalliferous mines and one coal mine in various regions in South ...
