It has no distinctive taste or smell. You would assume that because arsenic is a naturally occurring element it wouldn't even be a concern.
Arsenic is ubiquitous in distribution. In lime-stones and siliceous deposits its concentration ranges between 0.5 to 2.0 ppm while in volcanic rocks as much as 20 ppm of arsenic could be found. The highest concentration of arsenic almost 10,000 ppm has been recorded from Waitapu Valley in New Zealand and from Buns in Switzerland.
Arsenic Metals are basic elements that do not degrade any further, so they are able to persist in the environment. Metals may not always stay in the same form because they are able to react to form different compounds.

It is a natural component of the earth’s crust and you can find it in its gray, yellow and black form. In the environment it forms organic and inorganic chemical compounds as a result of natural and anthropogenic activities.
Arsenic toxicity, bioavailability and mobility are closely associated with its redox potential, chemical association and the textural class of the soil as well as the prevailing environmental conditions. In the soil, arsenic is usually associated with iron, aluminum and manganese hydroxides, clays and mineral oxyanions and organic matter.

Arsenic can exist in three different valency states: elemental arsenic (zero oxidation state); trivalent; or pentavalent arsenic. It forms alloys with metals and also readily reacts with.

The moment collection data on total arsenic focus can be hard to clearly identify the state of mort-aux-rats exposure. As a result, analysis of the exposure level by separating and quantification of each type of arsenic is needed. In addition, following assessments of arsenic direct exposure are had to establish ideal management guidelines.
