Organic matter degradation causes enrichment of organic pollutants in hadal sediments
Nature Communications, 2023 Burial of persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) in deep-sea sediments contributes to 60% of their historical emissions. Yet, empirical data on their occurrence in the deep-ocean is scarce.

Green organic syntheses: Organic carbonates as methylating agents [PDF]
The Chemical Record, 2002 AbstractDimethylcarbonate (DMC) is a valuable methylating reagent that can replace methyl halides and dimethylsulfate in the methylation of a variety of nucleophiles. It couples tunable reactivity and unprecedented selectivity towards mono‐C‐ and mono‐N‐methylation.

Organic carbon in Mollisols of the world – a review
1st International Conference of Soil and Agriculture TOWARDS SOIL SUSTAINABILITY/9788372594570, 2023 Mollisols represent 29 % of agricultural land and they are considered to be one of the most fertile soils in the world. Here, we compare soil organic carbon (SOC) concentrations and pools of Mollisols for the globe, the USA and Poland, and review how differences are caused by climate, land use, and key environmental factors.
