Arsenic is a highly toxic chemical element with an atomic number of 33, and atomic mass of approx. 74.92, and a chemical similarity to phosphorus that is so significant that it is the progenitor of the aforementioned highly toxic nature of the element. The most common charges for an individual atom of arsenic to possess are -3, +3, and -5.
Arsenic poisoning is the result of the allosteric inhibition of certain enzymes pertinent to metabolism, specifically, it replaces phosphorus is certain reactions, which results in their failing to function appropriately. This leads to cellular death, which in turn leads to tissue death and necrosis, and, if left untreated, death.
Oklahoma State University veterinary professor Dr. Billy Clay testified that the amount of arsenic used in animal agriculture is insignificant compared to what’s already in the environment. “Arsenic is very common in nature,” Clay said. “It's everywhere.”[1]
