Arsenic is a chemical element widely distributed in the earth's crust it is released from volcanoes and the erosion of mineral deposits, and is found throughout the environment in water, air and soil. In the natural environment, arsenic is rarely encountered as the free element more frequently it is a component of sulfidic ores, in which it occurs as metal arsenides, eg, nickel diarsenide, cobalt diarsenide, nickel arsenide, cobalt arsenide sulfide, copper arsenide sulfide, and iron diarsenide. Arsenic is one of the elements that is particularly prone to these polyatomic interferences for example, when determining 75as, a very common interference is from argon chloride (arcl) when 40ar and 35cl are present, the total mass is the same as 75as.

Arsenic is a naturally occurring element with a reputation as king of poisons as well as might actually be essential nutrients, according an analysis in the journal embo reports. Despite its notoriety as a deadly poison, arsenic is an essential trace element for some animals, and maybe even for humans, although the necessary intake may be as low as 001 mg/day arsenic is a component that is extremely hard to convert to water-soluble or volatile products. P s analytical specialise in the manufacture and supply of instruments for the analysis of arsenic, selenium and other hydride forming elements in addition to mercury.
Arsenic is a natural element that can be found in rocks and soil, water, air, and in plants and animals it can also be released into the environment from some agricultural and industrial sources although it is sometimes found in its pure form as a steel grey metal, arsenic is usually part of. 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.
