There are numerous standards and limits that apply to different contexts. Some common examples include:
Acceptable Daily Intake (ADI) - The amount of a substance that can be ingested daily over a lifetime without posing a significant risk to health. Reference Dose (RfD) - An estimate of a daily exposure to the human population that is likely to be without an appreciable risk of adverse effects over a lifetime. Maximum Contaminant Levels (MCLs) - Standards set by the EPA for drinking water quality to protect public health. Workplace Exposure Limits - Set by agencies like OSHA to regulate the amount of chemicals workers can be exposed to.
