Environmental context Episodic extreme rainfall events may affect metal dynamics in rivers flowing within historical metal mining areas. This study provides an analysis of the water chemistry and geochemical processes associated with mobilisation of metals during episodic rainfall events. Findings could be used to assess the environmental quality of streams draining spoil waste areas with similar geochemical conditions, and thereby be used to guide future management strategies.

EN17114Degradation of pentachlorophenol as a model hazardous and recalcitrant organochlorinated pollutant using AgIII
Environmental context. Electrochemistry offers potential applications for environmental remediation. Pentachlorophenol, a highly toxic and recalcitrant halogenated compound, is degraded by a novel oxidant produced electrochemically, and the intermediates and products of the degradation are investigated. Cyclic remediation systems merit further study.
EN17137Activation of sodium percarbonate with ferrous ions for degradation of chlorobenzene in aqueous solution: mechanism, pathway and comparison with hydrogen peroxide
Environmental context. It is practicable to remediate chlorobenzene-contaminated groundwater by in situ chemical oxidation. This study shows highly efficient degradation of chlorobenzene by an Fe-based process in a wide range of pH values. The technology is feasible for the removal of chlorobenzene from aqueous solutions and is appropriate for remediation of groundwater.
EN17161Analysis of trichloroethene vapour in soil-gas samples using solid-sorbent tubes with gas chromatography/mass spectrometry
Environmental context. Chlorinated chemicals are priority contaminants that pose significant risk to human health, and require state-of-the-art sampling techniques for varying matrices. A soil-gas sampling method was developed for the quantification of vapours of trichloroethene, a major chlorinated contaminant, present just above the groundwater zone. The method addresses sampling times, volumes and low-level trichloroethene concentrations.
Environmental context Fulvic acids are important naturally occurring organic materials, but unravelling their complex structures remains challenging. This paper suggests chemical analyses to facilitate structural studies of fulvic acids, and to investigate the similarities and differences of fulvic acids from various natural sources.
Environmental context. Redox potential is a controlling variable in aquatic chemistry. Through time series data, we show that microbial exudates released by bacteria may control trends in redox potential observed in natural waters. In particular, electron transfer between these exudates and the electrode could explain the values measured in the presence of abundant oxidants such as oxygen and nitrate.

EN17124Evaluation of phosphate-uptake mechanisms by Fe(III) (oxyhydr)oxides in Early Proterozoic oceanic conditions
Environmental context. Reconstructing the Precambrian oceanic P cycle, in conjunction with the As cycle, is critical for understanding the rise of atmospheric O2 in Earth’s history. Bioavailable phosphorus (P) has been found to regulate photosynthetic activity, whereas dissolved arsenic (As) maxima correlate with photosynthetic minima. New data on empirical adsorption and coprecipitation models with Fe(III) (oxyhydr)oxides suggest coprecipitation is a more efficient method of P sorption than is adsorption in Precambrian surface ocean conditions.
Environmental context. Microbes play key roles in controlling acidification and metal toxicity in coastal acid-sulfate soils. We characterised the time-dependent metabolic activities of abundant and rare taxa in acidifying tidal wetlands and showed that rare taxa exhibiting higher activity may exert significant influence on iron- and sulfur-cycling. Our findings yield new insights into the drivers and timing of iron- and sulfur-cycling in coastal acid-sulfate systems.
