Several key regulatory standards are followed to ensure safety:
1. Maximum Contaminant Levels (MCLs): Set by the EPA for drinking water contaminants. 2. Permissible Exposure Limits (PELs): Established by OSHA for workplace exposure. 3. Acceptable Daily Intake (ADI): Defined by the FDA for food additives and contaminants. 4. Reference Dose (RfD): A daily exposure level determined by the EPA that is likely to be without significant risk of adverse effects.
