A pharmaceutical hazardous waste identification and management system integrates disparate information regarding pharmaceuticals to provide an indication of which pharmaceuticals are hazardous wastes as defined by respective national, international and state regulations and/or which are hazardous materials as defined by the US OSHA regulations. A subset of this information offers a global repository with respect to the occurrence, concentrations, and ecotoxicologic data of pharmaceuticals based on peer reviewed data provided by environmental toxicologists and related scientists.
