The report presents computational approaches that can be used for the relatively rapid identification of suspect toxigens, including carcinogens, in two different classes of compounds: halogenated olefins and epoxides, and substituted dibenzo-p-dioxins. A common element in these approaches is the key role played by the molecular electrostatic potential. It is applied in two different ways, however; it is used to assess the reactivity of a specific site in the case of the epoxides, and for the dibenzo-p-dioxins the focus is on the overall pattern of negative regions above the molecular plane. Results obtained so far are encouraging and indicate that these can be regarded as useful screening techniques for identifying compounds that require further and more exhaustive investigation.
