The U.S. Environmental Protection Agency (EPA) conducted soil sampling in August 2017, December 2017, and June 2018 to depths of two feet at several private properties at the Arsenic Mine site near Pine Pond in Kent, Putnam County, New York. This historic mine was operated from the mid-1800s through approximately 1918.

The South West became the world's main producer in the late 19th century. Arsenic was used in the glass industry, in making enamels, paints and insecticides. The arsenic mine and works known as Gawton Mine is considered to be the best, most complete surviving example of this type of mining, ore dressing, calcining and refining works in the country.

Realgar is a monoclinic arsenic sulfide mineral with a brilliant red color and a chemical composition of As 4 S 4. Well-formed realgar crystals can look so much like red gemstones that the mineral was often called "ruby sulfur" and "ruby arsenic." However, realgar is not used as a gemstone because it is very soft, with a Mohs hardness of just 1 ...

Crop and livestock farming on contaminated soil has been found to induce the accumulation of trace elements in edible parts of plants, with subsequent risk to human and animal health. Since rice crop is a major source of energy in worldwide diets and is consumed by more than 3 billion people, the soil–rice pathway is regarded as a …
