Sorption of Non-Polar Organic Compounds by Micro-Sized Plastic Particles in Aqueous Solution
Thorsten Hüffer,Thilo Hofmann +1 more
TL;DR: A strong relationship between the sorption coefficients of the microplastics and the hydrophobicity of the sorbates suggests that hydrophobic interactions are of major importance.

Sulfate radical-based water treatment in presence of chloride: Formation of chlorate, inter-conversion of sulfate radicals into hydroxyl radicals and influence of bicarbonate
TL;DR: At moderate Cl(-) concentrations (mM range) the SO4(-)-based process may be converted into a conventional (hydroxyl radical -based) advanced oxidation process and the conversion of SO4(-) into OH, however, is interrupted in presence of bicarbonate by scavenging of Cl.
Journal ArticleDOI
Microplastics as vectors for bioaccumulation of hydrophobic organic chemicals in the marine environment: A state-of-the-science review.
TL;DR: Evidence is weak to support the occurrence of ecologically significant adverse effects on aquatic life as a result of exposure to HOCs sorbed to microplastics or to wildlife populations and humans from secondary exposure via the food chain.

TL;DR: Filtration and sorption technologies offer the most promising existing removal methods for PFAs in aqueous waste streams, although sonochemical approaches hold promise.

Additivity principles in biochemistry.
TL;DR: The authors cannot yet reliably fold proteins or RNA molecules by computer, predict ligand binding affinities, compute conformational transitions, or use the sequence information in the Human Genome very effectively to understand biomolecular function and disease.
