Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body. If arsenic poisoning occurs over a brief period of time symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Longterm exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and cancer.
Arsenic is used industrially as an alloying agent, as well as in the processing of glass, pigments, textiles, paper, metal adhesives, wood preservatives and ammunition. Arsenic is also used in the hide tanning process and, to a limited extent, in pesticides, feed additives and pharmaceuticals. Tobacco
Environmental characterization was conducted in one mining and one smelting community in Armenia, Akhtala and Alaverdi, respectively. The aim of the study was to quantify the levels and possible origins of arsenic and lead in the residential soil of these communities, and measure the relationship between those levels in the soil, and its proximity to the industrial source.
Dec 16, 2019· Known as process water ponds, the basins allow muds that are washed from grains of frac sand to settle from water that is reused in the process.

Apr 25, 2017· What Is The Environmental Impact Of The Mining Industry? Water pollution, loss of biodiversity, soil erosion and pollution, and formation of sink holes are among the worst effects of the mining industry on the environment.
Arsenic is found in rocks containing many other elements, and is often released in the process of mining and smelting other metals. Mining and smelting sites often pose serious risks to local communities, particularly to children. Arsenic cannot be destroyed, and thus remains in surface soil long after the event that released the arsenic has ...
