TL;DR: The liquid chromatography-electrospray ionization-tandem mass spectrometer (LC-MS/MS) method coupled with an automated solid-phase extraction procedure has been developed to identify 22 psychiatric pharmaceuticals in wastewater samples from two psychiatric hospital wastewater treatment plants and three municipal wastewater Treatment plants in Beijing, China.

TL;DR: It is found that mercury enrichment and isotope records in marine sections across the globe can be linked to increased volcanic activity, which resulted in the protracted Permian-Triassic biocrisis.

TL;DR: In this paper, a combustion-trapping dual-stage protocol was proposed for preconcentration of Hg from a PM sample collected on a quartz fiber membrane (QFM) for high-precision Hg isotopic analysis.

TL;DR: In this paper, Zhao et al. examined, for the first time outside North America, both mass-dependent fractionation (MDF, expressed as δ202Hg) and mass-independent fractionation of odd (odd-MIF, Δ199Hg), and even (even-Mif, Δ200Hg)-Hg isotopes in 15 precipitation samples collected from September 2012 to August 2013 in Guiyang (SW China).

TL;DR: In this article, the isotope compositions of surface water and sediments of 8 freshwater lakes in Ontario, Canada have been investigated and the authors concluded that the source of Hg in lake surface water is likely dominated by direct atmospheric precipitation, while the Hg content in lake sediments is primarily derived from watershed inputs of terrestrial particles.
