Exposure assessment is a critical component of toxicity risk assessment. It involves characterizing how, when, and for how long individuals are exposed to a chemical. Exposure can occur through various routes, including inhalation, ingestion, and dermal absorption. The level and duration of exposure significantly impact the potential toxic effects. For instance, a substance may be safe at low concentrations but toxic at higher levels. Accurate exposure assessment helps in determining the real-world risk of toxicity.
