Its stable form is a silver-gray brittle crystalline solid that does not exhibit any characteristic smell or taste. Owing to its membership to the Va group of the periodic table, it readily combines with other elements to produce organic arsenic compounds (when in combination with carbon and hydrogen) and inorganic arsenic compounds (when in combination with oxygen, chlorine and sulfur) (Marcus, 2006; Nriagu, 1994).
The occurrence of arsenic in the environment can be considered as an important notion in the study of the effects and toxicology. The name of Arsenic is equated to poison, due to the effects that it can bring about to the different organisms and components of the environment. The said chemical can be considered as toxic due to its reactivity. It occurs in different forms that are commonly reactive due to the fact that it is considered as a heavy metal but its use in different industries and the by-products produced intensifies the effects of arsenic (Marcus, 2006).
Although natural arsenic can be found in certain amounts in the environment, accumulation increases the hazardous effect of the chemical. Effects of arsenic can be attributed to the exposure in relation to the industrial process and accumulated amounts in the environment. For this reason, it is important to consider the need to regulate the application of arsenic in different industries.
