Arsenic is a heavy metal which is highly poisonous and carcinogenic, produce very harmful effect to human body. Arsenic is a semi -metal element, its symbol is as and atomic no33. arsenic and its compound especially the trioxide are used in the production of pesticides, treated wood product herbicides and insecticides these application are decline due to the toxicity of arsenic and its compound. Organic arsenic is less harmful than inorganic arsenic. Seafood is a common source of the less toxic organic in the form of arsenobetain. Man-made sources of arsenic are generally by-products of the smelting of nonferrous metal ores, primarily copper and to a lesser degree lead, zinc, and Gold. Organic arsenic compounds tend to be eliminated in the urine in unchanged form, while inorganic forms are largely converted to organic arsenic compounds in the body prior to urine excretion. In Long term exposure Arsenic poisoning may develop the symptoms as change in the fingernail pigmentation, a metallic taste in the mouth and garlicky breath, blood in urine, hair loss and cramping muscles, convulsions, excessive sweating and problem in swallowing. More recent finding show that consumption of water with levels as low as0.00017mg/L(0.17 parts per billion)over long periods of time can lead to Arsenicosis.
