Arsenic is a metallic form that is normally used in the making of alloys in the industrial sector. In combination with lead and copper, it gives this unique smoothness to the alloy or leads ammunition. 8. Joint pain healer. Arsenic is present in some herbal foods most especially in the Asia region.
The metals and metalloids like As in agricultural soil have become a serious concern due to their adverse ecological impacts (Moulick et al. 2022; Chowardhara et al. 2019a, b). Arsenic present in the ecosystem can enter the food chain either through the As-contaminated drinking water or by consumption of foods grown in As-rich soil.
Abstract. Pollution from potentially toxic metalloids such as arsenic is becoming a major concern for living organisms all over the world. Arsenic (As) is a non-essential metalloid in plants that can build up to toxic levels. As-contaminated soil remediation ought to be sustainable, low-cost, and applicable in the most vulnerable low …

Arsenic doesn't seem much like a metal in its so called yellow form, but it also has a grey form known tellingly as metallic arsenic. Yellow arsenic has a specific gravity of 1.97 …
Commercial production and uses. Metallic arsenic forms when arsenopyrite is heated at 650–700 °C in the absence of air. The arsenic in arsenopyrite and the arsenic impurities in other metal ores unite readily with oxygen when heated in air, forming the easily sublimed oxide, As 4 O 6, also known as "white arsenic."The vapor of the oxide is …
Arsenic is a metalloid element with symbol As and atomic number 33. Arsenic is a chemical element with the symbol As and atomic number 33, making it a …
Arsenic (As) is one of the most hazardous heavy metal found in nature. It has the symbol As, the atomic number 33, and a relative atomic mass of 74.92. Arsenic, which comes from the Greek word arsenikon, which means "potent," has been employed as a tonic and a poison since ancient times.
arsenic and arsenic containing compounds were released into the environment in 1997. • Arsenic is found in the preservative chromated copper arsenate (CCA) used to preserve …
In arsenic-rich geothermal locations, arsenic absorptions in tributaries after mixing with arsenic-rich geothermal seawaters were found to be between 10 and 100 g/L or more (He et al., 2021). Okpashi and Abeng ( 2020 ) noted that surface water arsenic levels rose as a result of water released from mining waste.
The system was in continuous operation during 343 days, fed by groundwater with arsenic concentration at 90.66 ± 14.95 µg L −1, and a hydraulic retention time of 2 days. Monitored parameters were: redox potential, pH, dissolved oxygen, water and environmental temperature, arsenic concentration inlet and outlet.
A primary source of arsenic to drinking water wells is from water flowing through arsenic-rich rocks and soil. It can be further released into the environment through natural activities such as volcanic action and forest fires, as well as through human actions. Arsenic is used in paints, dyes, metals, drugs, soaps, and semiconductors, as well ...
1Arsenic content of arsenic metal is ; arsenic content of arsenic compounds is 77.7% for arsenic acids, 60.7% for arsenic sulfides, and 75.71% for arsenic trioxide. 2Arsenic content estimated from the reported gross weight of imports. 3Estimated to be the same as total imports. 4Minimum 99% arsenic.

Properties. Arsenic has a valence of -3, 0, +3, or +5. The elemental solid primarily occurs in two modifications, though other allotropes are reported. Yellow arsenic has a specific gravity of 1.97, while gray or metallic arsenic has a specific gravity of 5.73. Gray arsenic is the usual stable form, with a melting point of 817°C (28 atm) and ...
Heavy metal contamination is frequently caused by mining, the manufacturing of fuel, fertilizers used in agriculture, and vehicle emissions (Amin et al. 2013).
