Specific Substances: Benzothiazole
Nomination Date: 09/30/1997
Rationale: Benzothiazole's nomination is based on its: 1) potential for human exposure from its presence in foods and beverages, and as an environmental contaminant; 2) lack of chronic toxicity data; 3) lack of information about the benzothiazole moiety, which is present in many common products. Benzothiazole may leach from rubber stoppers into parenteral solutions. Through weathering of an antioxidant from tires, road dust and street runoff contribute additional potential for exposure.
