Occurrence of arsenic contamination in Canada: sources, behavior and distribution.
TLDR
An analysis of the currently available information on recognized problem areas, and an overview of current knowledge of the principal hydrogeochemical processes of arsenic transportation and transformation are provided, however, a more detailed understanding of local sources of arsenic and mechanisms of arsenic release is required.About:

Arsenic removal from water/wastewater using adsorbents—A critical review
Dinesh Mohan,Charles U. Pittman +1 more
TL;DR: Strong acids and bases seem to be the best desorbing agents to produce arsenic concentrates, and some commercial adsorbents which include resins, gels, silica, treated silica tested for arsenic removal come out to be superior.

Technologies for Arsenic Removal from Water: Current Status and Future Perspectives
TL;DR: An overview of the available technologies used nowadays for the removal of arsenic species from water is presented and promising future research on novel porous materials, such as metal organic frameworks, is suggested.
Book ChapterDOI
Arsenic pollution sources.
TL;DR: Past and current mining activities continue to provide sources of environmental contamination by arsenic, and evidence suggests that increased use of geothermal power may elevate risks of arsenic exposure in affected areas.

Arsenic toxicity in crop plants: physiological effects and tolerance mechanisms
Neera Garg,Priyanka Singla +1 more
TL;DR: The role ofArsenic speciation in the environment and how As is taken up by the roots and metabolised within plants, and the role of arbuscular mycorrhizae in alleviating arsenic toxicity in crop plants are reviewed.

Heavy Metal Stress, Signaling, and Tolerance Due to Plant-Associated Microbes: An Overview.
Shalini Tiwari,Charu Lata +1 more
TL;DR: This review takes into account the current state of knowledge of the harmful effects of heavyMetal stress, the signaling responses to metal stress, and the role of plant-associated microbes in metal stress tolerance, and highlights the challenges and opportunities.

A review of the source, behaviour and distribution of arsenic in natural waters
TL;DR: The scale of the problem in terms of population exposed to high As concentrations is greatest in the Bengal Basin with more than 40 million people drinking water containing ‘excessive’ As as mentioned in this paper.

Quantitative assessment of worldwide contamination of air, water and soils by trace metals
Jerome O. Nriagu,Jozef M. Pacyna +1 more
TL;DR: Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements.
