What Is the Role of Risk Assessment in Regulatory Toxicology?
Risk assessment is a systematic process used to evaluate the potential health risks associated with exposure to hazardous substances. It involves four key steps:
Hazard Identification: Determining whether a substance can cause harm. Dose-Response Assessment: Establishing the relationship between the dose and the severity of the effect. Exposure Assessment: Estimating the extent of human exposure to the substance. Risk Characterization: Integrating the information from the previous steps to describe the nature and magnitude of the risk.
