ABSTRACT
Arsenic, a widely distributed metalloid element, ranks the 20th in abundance in the Earth’s crust, the 14th in the seawater, and the 12th in the human body (Mandal and Suzuki, 2002). Due to its carcinogenesis and mutagenesis, arsenic is a notorious contaminant, which poses serious health risks to humans and animals. Health effects including cancers of the skin and internal organs have been linked to chronic exposure to arsenic in drinking water (Azcue and Nriagu, 1994; Frankenberger, 2002).
