Arsenic clearly shares similar concentration distributions with organic carbon, sulfur, and iron (Fig. 2).Statistical correlations of elemental abundance with arsenic and …
Arsenic is a hazardous environmental contaminant that can pose serious toxic harm to lives. As pollution in aquatic ecosystems has been increasing in recent …
The dominant accumulation mechanism of arsenic in oxygenated sediment is the co- precipitation of arsenic to hydrous iron oxides (Nicholas et al., 2003).
Bacteria are essential in arsenic cycling. However, few studies have addressed 16S rRNA and arsenic-related functional gene diversity in long-term arsenic …
Arsenic (As) is reputed to be a redox-sensitive element but has not been fully explored yet as a proxy in marine sediments and sedimentary rocks, compared to …
To date, three main mechanisms have been proposed for As mobilization in groundwater: (1) the reductive dissolution of As-bearing iron (Fe) oxides under …
Distribution and hosts of arsenic in a sediment core from the Chianan Plain in SW Taiwan: implications on arsenic primary source and release mechanisms Sci. Total Environ., 569–570 ( 2016 ), pp. 212 - 222
Arsenic enters groundwater naturally from rocks and sediment by coupled biogeochemical and hydrologic processes, some of which are presently affected by …
This study provides the first insight into the impact of sedimentation history on As distributions in sediment profiles in the Hetao Basin. To understand the impact of …
