“…The element can reach the atmosphere from emissions (natural and anthropogenic) and aerosols, being found as volatile As and As in particulate matter (soils, sediments). The primary natural sources of As emissions correspond to volcanic activity [48,49]. Human activity contributes to 75% of the As present in the atmosphere [50].…”

“…However, it is known to be generally low, except at specific points where emissions occur from smelting activities, fuel oil combustions, or other industrial activities [51]. In general, As(V) is the main arsenic species in aerosols, and the As(III) content is much lower [49]. The U.S. OSHA states that the permissible exposure level (PEL) for As is 10 mg m -3 air.…”

This paper reviews the arsenic in the environment. Arsenic contamination is currently one of the leading environmental problems worldwide. The arsenic (As) cycle is the subject of this article because As is an element with a significant impact on living beings and because of its interrelation with other biogeochemical cycles. The biogeochemical cycle of As is closed, so this trace element returns to sediments where it can be changed in its chemical state by micro-organisms present in soils. In addition, some minerals contribute to the sequestration and retention of As. This element interferes with other critical biogeochemical cycles such as sulfur, phosphorus, iron, manganese, and antimony. Another factor to consider is determining the content and interference of organic matter in the soil, as it forms very stable compounds with As. On the other hand, in aquatic environmental conditions, with a high concentration of organic matter and anaerobiosis, a reducing environment is created that facilitates the mobilization of As in the sediments.
