What is Arsenic?

Arsenic is a semi-metallic chemical element that occurs naturally in rocks, soil, water, air, plants and animals and is widely distributed in nature in very low concentrations, including trace amounts in everyday foods like chicken, fish, rice and beans.

Although arsenic is toxic in its basic form, this toxicity depends on the quantity, form of presentation and exposure time of the element. Health and environmental agencies have done extensive research to establish acceptable lifetime exposure levels without appreciable risk.

Arsenic Facts

Arsenic is a naturally occurring element, present in rocks, and is dispersed into the environment through the natural processes of weathering and erosion.

In Paracatu and many other parts of the world, naturally occurring arsenic levels vary depending on underlying geological formations.


Safe Levels

The effects of arsenic on human health, in the form of diarsenic trioxide, have been known since ancient times, and human exposure to elevated levels of arsenic occurs mainly through food.

For this reason, in a review of the latest scientific evidence conducted in 2010, the World Health Organization (WHO) together with the Joint Food and Agriculture Organization of the United Nations (FAO) has established a variety of acceptable benchmark levels for arsenic intake.
