Toxicological evaluations typically follow a series of structured steps:
Hazard Identification: This involves determining whether a substance can cause harm. It includes reviewing existing data and conducting toxicological tests. Dose-Response Assessment: This step assesses the relationship between the amount of exposure and the extent of toxic effect. It helps in determining the threshold level of toxicity. Exposure Assessment: Evaluates how much, how often, and how long humans and other organisms are exposed to the substance. Risk Characterization: This is the final step where the data from the previous steps are integrated to estimate the health risk posed by the substance.
