Arsenic contamination is a problem in some well-water and may be associated with mine drainage. Arsenic is not recovered from any waste materials or in any recycling program. Some is recovered from runoff at wood treatment facilities. Interestingly, a trace amount of arsenic is necessary for good health and growth of animals, including humans ...

3.1. Arsenic-bearing mine waste. Over 300 minerals can contain or host As. Most are arsenates (roughly 60%) and sulfides or sulfosalts (roughly 20%); the remaining are primarily arsenides, arsenites, oxides, and elemental As (Alloway, Citation 1995; Drahota & Filippi, Citation 2009).The common primary minerals of As include …

Arsenic is a natural component of the earth's crust and is widely distributed throughout the environment in the air, water and land. It is highly toxic in its inorganic form. People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops ...

Mining activities are the main anthropic source of As release to the environment. Gold mine tailings and effluents generally contain high concentrations of arsenic and are a cause for concern as potential sources of environmental contamination . In addition to solid and liquid tailings, mining is also responsible for releasing As into the ...

The Arsenic Mine Site includes a former mine that was operated intermittently from the mid-1800s through approximately 1918 to extract arsenic for manufacturing products, such as pesticides, pharmaceuticals and chemicals. Decades later, residential houses were built on properties around and downslope from the former mine.

At the mine itself, they found almost 19,000 micrograms of arsenic per liter in the water. In Zaouit Sidi Blal, a date-farming community 4.3 miles (7 kilometers) from the mine, they found just ...

Arsenic-associated squamous cell carcinomas are distinguished from ultraviolet-induced squamous cell carcinomas by their tendency to occur on the extremities (especially palms and soles) and trunk, rather than on sun-exposed areas such as the head and neck. However, it may be difficult to distinguish other arsenic-induced skin lesions from ...
