,,-Di-chlorido-bis-(,-di-methyl-pyridin-4-amine-κ)bis-(dimethyl sulfoxide-κ)ruthenium(II).

The structure of the title compound, [RuCl(CHN)(CHOS)], has monoclinic (2/) symmetry. The Ru-N distances of the coordination compound are influenced by the chloride or di-methyl-sulfoxide-κ ligands. The mol-ecular structure exhibits disorder for two of the terminal methyl groups of a dimethyl sulfoxide ligand.

Assessing the sorption of pharmaceuticals to microplastics through in-situ experiments in New York City waterways.

Adsorption of organic pollutants onto microplastics has been reported in prior studies, indicating the potential of these particles to serve as vectors of pollutants. Most prior investigations, however, have been conducted in laboratories under conditions with relatively little environmental relevance. Here we report the results of in-situ experiments to investigate the adsorption of pharmaceuticals (atenolol, sulfamethoxazole, and ibuprofen) on to eight types of test materials (pellets from five types of widely-used polymers, small pieces of straws, fragments of bags, and glass beads for control).
