TL;DR: A cross-scale analysis of paired-stressor effects on biological variables of European freshwater ecosystems shows that in 39% of cases, significant effects were limited to single stressors, with nutrient enrichment being the most important of these in lakes.

TL;DR: Wang et al. as discussed by the authors analyzed water quality data, recorded between 2006 and 2014 in 862 freshwater lakes in four geographical regions of China, to assess the input of phosphorus from human activity.

TL;DR: Analysis of the X-ray absorption spectroscopy (XAS) spectra of sorbed complexes implied that monothioarsenate binds to Fe oxides as a monodentate, inner-sphere complex, and mono- and tetrathioARSenate were both unstable and partially reduced to arsenite.

TL;DR: In this article, an inverse modeling approach based on a one-dimensional transport-reaction equation assuming steady-state, was applied to the porewater As profiles and used to constrain the net rates of reactions involving As (R net As ).

TL;DR: It is shown that changes in municipal wastewater treatment are a major driver for increases in lake TN/TP mass ratios, as phosphorus is more effectively removed than nitrogen from wastewater, and long-term strategies for domestic wastewater management should not merely focus on total reductions of nutrient discharges but also consider their stoichiometric balance.
