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).

MOF-74(Co) NPs lower root length, fresh weight and dry weight of pea seedlings. MOF-74(Co) NPs decreased net photosynthetic rate and increased intercellular CO2 content. Released Co ions induced oxidative stress and damaged photosynthesis system II.
