I Introduction

Arsenic is a metalloid element that occurs in nature in both organic and inorganic compounds. The valence of arsenic is three in arsenite (As (III)) and five in arsenate (As (V)) compounds. Arsenic compounds are poisonous and can be categorized into one of three broad categories, all with different toxicities: organic arsenic compounds, inorganic arsenic compounds and their solutions, and arsine gas. Of these, inorganic compounds are of relatively greater toxicological significance for human health than are organic compounds. Toxicological profiles for arsenic compounds have been published both in standard texts (Ishinishi et al. 1986) and in reports produced for international and governmental agencies (IARC 1982; ATSDR 2000; IPCS 2001). The reader is referred to these for a comprehensive description of the toxicokinetics and toxicity of arsenic. The purpose of this chapter is to review the salient health risks posed by arsenic contamination, with special reference to...
