Review on Toxic Effects of Arsenic with relation to Clinical Signs in Different Animals

Arsenic is natural metalloid which is present in the universe everywhere. It is used for different insecticides and pesticides preparation. Poisoning of arsenic is a major issue that affects different species. Its occurrence is related to contamination of feed and water; therefore, it is matter of concern globally. However, its level of toxicity is increasing very rapidly in Asian countries especially Bangladesh, India and Pakistan. Its increasing level of arsenic in ground water is the major source of poisoning to human and animals. In addition, the contact of animals to arsenic lead to absorption body and accumulation in vital organs like liver and kidneys that may resulted to carcinogenic development. Elimination of absorbed arsenic in environment through excretions of animals is also one way to increase its level in water/soil. The objective of this review is to gather the information about arsenic toxicity occurrence by natural or experimentally ways and changes occurred in suffered animals related to pathological or biochemical.
