The uptake of total gaseous mercury (TGM) by Korean forest foliage is mainly affected by local wind speed, boosting its passage and absorption. Mercury levels and isotopic signatures in litter and topsoil fluctuate, particularly in areas with high wind speed, temperature, and low elevation.

Coccolithophores are biogeochemically and ecologically important phytoplankton that produce calcium carbonate scales, or coccoliths. Here, we show that one species of coccolithophore grows coccoliths with uneven distribution of Sr, in contrast to current fractionation model theory.

When the unsaturated CIs at the CC-terminal vinyl electrophilic center react with the OC–OH moiety (TFA), a new adduct, TFAAAH, is formed, and it can act as a potential source of secondary organic aerosols (SOAs).
