Structure-activity relationships
Structure-activity relationships may be useful to increase the weight-of-evidence or human health hazards identification. Where classes of compounds are of interest (e.g., polycyclic aromatic hydrocarbons, polychlorinated biphenyls and dioxins) and where adequate toxicological data are available on one or more members of the class, a toxic equivalence approach may be useful to predict the human health hazard associated with exposure to other members of the class.
