Expose to dust with elevated arsenic levels may come from agricultural (use of pesticides and fungicides and farming), mining (mine tailings, smelters, particles high in arsenic), inhaling smoke (burning of oil, gasoline, wood, coal), and lifestyle activities such as tobacco smoking (tobacco products have small amounts of arsenic, because of ...
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. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and cancer.
Arsenic's name comes from the Greek term for an arsenic compound, orpiment (arsenic trisulfide). Arsenic is a metalloid element, which, like phosphorus, has two main forms. One is a brittle, gray metallic form and the other is a yellow, non-metallic solid.
Gold mining and processing operations are important sources of arsenic release to the environment. This chapter focuses on the magnitude of the arsenic problem in gold processing and the methods used to mitigate the risk to the environment.
Arsenic in Coal Printed on recycled paper Sources of Arsenic Arsenic is a persistent toxin that occurs naturally in trace amounts in rocks, sediments, and coal. Small ... Arsenic in Waste from Coal Mining, Processing, and Storage Mining operations in the United States generally must meet water-quality stan-dards for discharge of mine water. In some
Introduction. Arsenic (As) is a carcinogenic metalloid ubiquitous in the environment, and is obtained from natural and anthropogenic sources, .Anthropogenic activities such as metal mining and smelting, the use of As-containing pesticides, herbicides, wood preservatives, feed additives, and irrigation with As-rich groundwater, have resulted in elevated As levels in soil, .
Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal.Arsenic is a metalloid.It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.. The primary use of arsenic is in alloys of lead (for example, in car batteries ...
Context - Arsenic is a poisonous substance, which is released both from certain human activities and naturally from the Earth's crust.. Humans may be exposed to arsenic mainly through food and water, particularly in certain areas where the groundwater is in contact with arsenic-containing minerals.
Several case histories of the pre-mining arsenic content in surface and ground water on gold mining projects throughout western United States and Alaska are presented. The technical aspects of an elevated arsenic content in surface and ground water, mined areas, and waste disposals are discussed.
Arsenic is also released into the environment through the discharge of industrial waste in coal-fired power plants and incinerators, mining, smelting, combustion of fossil fuels, and the drilling of wells.

Arsenic in the mining industry . Atmospheric arsenic emissions from copper smelting represent the largest contribution of arsenic from the mining and metals industry by far and have been the focus of pollution control technologies and increasingly stringent regulations.  ...
Arsenic is a naturally occurring element found in earth's crust. It is an odorless and tasteless semi-metal element. In the Periodic Table, its symbol is As and its atomic number is 33. Although arsenic is toxic to humans, it is used in a number of industries and released into the environment.
In those tailings is a toxic byproduct of the mining process: arsenic, in concentrations up to 50 times higher than the level deemed safe by the government. Now Pyle finds that her house is virtually worthless; no one will buy it, and no bank will write a mortgage.

The use of different fertilizer materials and fertilization practices also influences the soluble arsenic content of soils and the arsenic content of the harvested crop. 757 A high phosphate application to soils receiving arsenicals increases the arsenic content of corn foliage, but apparently not of corn seed.
Arsenic. Arsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores.
Arsenic mine tailings and health Arsenic is a substance found in the environment. It occurs naturally in crushed rock. It is often found near gold deposits and is extracted as part of gold and other mining activities.
