Arsenic (As), an elemental metalloid, occurs primarily in metallic and sulfide ores. Both natural (e.g. volcanoes, weathering, and leaching) and anthropogenic activities (e.g. mining, wood preservation, etc.) determine its current global distribution. Water sources (particularly groundwater), ...

Arsenic is the 53rd most abundant element and is widely distributed in the Earth’s crust.It occurs naturally in several minerals, but high-grade deposits are rare. Most of the mineralsand ores that contain arsenic also contain other metals. Some major sources of arsenic are theminerals orpime...
Hokusetsu Region in Osaka, Japan. Study focus The As contamination was investigated through the geochemical mapping and analysis of river waters and bed sediments over an area of 440 km2. Sulfur from sulfides in rocks and dissolved sulfates in water were compared via isotopic analysis to assess ...
provide a greater understanding of the extent, concentrations and possible sources of arsenic in drinking water from private wells in the White Rock-Surrey-Langley area. Elevated arsenic levels have been reported in a number of locations in B.C. in the past ...
Notably, the arsenic concentration in natural water sources vary quite signifi- cantly at different times of the year, especially before and after the rainy season (Supplementary Table S1)5. We thus collected water from the local area at different times of the year to confirm the efficiency ...
Arsenic contamination of groundwater resources threatens the health of millions of people worldwide, particularly in the densely populated river deltas of Southeast Asia. Although many arsenic-affected areas have been identified in recent years, a system
Co-occurrence, possible origin, and health-risk assessment of arsenic and fluoride in drinking water sources in Mexico:geographical data visualization. Sci. Total Environ. 698, 134168. [6] Alcaine, A.A., Schulz, C., Bundschuh, J., Jacks, G., Thunvik, R., Gustafsson, J.P., Mörth...
The presence of toxic metals in groundwater sources is an important issue in water and wastewater treatment, as their consequences on human health have been well established [1]. Among them, arsenic contamination of groundwaters concerns several countries around the world and has been recorded by ...
