Arsenic

Arsenic is a naturally occurring allotropic pnictogen and metalloid trace element with atomic symbol As, atomic number 33, and atomic weight 74.92 that is found in water, air, food, and soil, and has a role as a micronutrient. Arsenic, which is highly toxic with acute or chronic exposure to moderate or high levels through an unknown mechanism of action, is used in many industrial processes, as Get price

UpToDate

2019/1/7Elemental arsenic is rare, and the element exists more commonly as organic or inorganic compounds []. Arsenical compounds can be grouped as inorganic, organic, and arsine gas (AsH3). They are further classified according to their valence states: elemental (0), arsenite (trivalent, +3), and arsenate (pentavalent, +5). Get price

Arsenic exposure, genetic susceptibility and leukocyte

Abstract. Arsenic-induced health effects may be associated with critically shortened telomeres. However, few data are available on the effects of arsenic expo As expected, LTL was inversely correlated with age ( r = −0.226, P = 0.0004), but no significant associations were found between LTL and gender (1.0310.3 versus 1.0270.3, P = 0.8; for male and subjects, respectively) and Get price

Influencing food policy with arsenic testing

But although a maximum level of inorganic arsenic in water was established in the 1990s, there were no recommendations for arsenic in foodstuffs. Due to the different forms of arsenic found in food, major authorities in the UK and EU felt that data and research was limited around the arsenic compound that causes cancer, and that a maximum level could only be determined after further investigation.
