Arsenic Factsheet | National Biomonitoring Program | CDC

Inorganic arsenic compounds are in soils, sediments, and groundwater. These compounds occur either naturally, or as a result of mining, ore smelting, or when using arsenic for industrial purposes. Organic arsenic compounds exist mainly in fish and shellfish. In the past people used inorganic forms of arsenic in pesticides and paint pigment

Arsenic pollution sources - PubMed

When humans are implicated in causing or exacerbating arsenic pollution, the cause can almost always be traced to mining or mining-related activities. Arsenic exists in many oxidation states, with arsenic (III) and (V) being the most common forms. Similar to many metalloids, the prevalence of particular species of arsenic depends greatly on the

Arsenic | Minerals Education Coalition

Arsenic occurs in pure form only in small deposits. It occurs in many minerals, and usually is obtained as a by-product from the mining, processing and refining of other minerals. Common arsenic-bearing minerals include arsenopyrite, conichalcite, enargite, lollingite (iron arsenide), olivenite and orpiment

The Management of Arsenic in the Mining Industry

Arsenic contamination is often associated with historic gold mining activity since arsenic commonly occurs in the ore of gold bearing metal sulfide deposits (Cohen and Bowell, 2014)

Treating Arsenic and Selenium in Mine-Influenced Waters

Arsenic is, unfortunately, a common groundwater contaminant. Water and wastewater that contain arsenic require treatment because it is toxic to animals that, and humans who, ingest it. Selenium is a metal that normally occurs in minerals, especially minerals that contain sulfide, an anion of sulfur, along with copper, lead, silver, and nickel

Coal Mining and arsenic poisoning in Bangladesh

Oct 09, 2004 But in other countries, the arsenic pollution has a human source. Mining, smelting, pesticide spraying and coal burning all pollute the environment with arsenic. Pesticides.

A Combined Remediation Strategy of Arsenic and Cadmium

Jun 10, 2021 The combined pollution of arsenic (As) and cadmium (Cd) are quite common in the polymetallic mining areas located in southern China. In the present study, field experiments were established for the purpose of exploring a simultaneous remediation strategy of rice variety-water management-contaminant immobilization on the As and Cd contamination in paddy soil. The obtained

Sources of Arsenic Exposure | Toxno

Jun 18, 2018 Nitrates (from agriculture make uranium, arsenic (either natural or from mining activities) and other heavy metals more soluble. Uranium in the presence of nitrates creates the substance, uranyl nitrite, which is extremely toxic to kidneys. When children were tested in the area and had positive levels of arsenic, the symptomatic result was

Case reports: arsenic pollution in Thailand, Bangladesh

Arsenic water levels to 9,000 pg/L were reported; such levels are substantially above any guideline levels. A long-term plan to mitigate arsenic contamination was devised in 1998-2000. The plan involved removal of arsenic-contaminated land and improved management of mining wastes

Minerals | Free Full-Text | Pilot-Scale Removal of Arsenic

This study was conducted to assess the removal of arsenic (As) and heavy metals from mining wastewater by the combination of adsorption, using modified iron-ore drainage sludge, and horizontal-subsurface-flow constructed wetland with common reed (Phragmites australis). The pilot-scale experiment with a constant flow rate of 5 m3/day was operated for four months using real wastewater
