ABSTRACT
The tragic accidental release of methylisocyanate in Bhopal, India in 1985, resulted in the death of over 2000 people (U.S. EPA, 1988). This incident lead to the realization by both the chemical industry and the regulatory community of the need to pool resources for the development of emergency response plans for areas near chemical production sites (Gephart et al., 1986; Gephart and Moses, 1989). These activities have been occurring at many levels around the world. In Europe, for example, the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC), formed a task force that published a guide for reviewing chemicals and estimating the hazard associated with an accidental release (ECETOC, 1991).
