Assessing the hazardous nature of a substance involves several key steps, including risk assessment, hazard identification, dose-response assessment, and exposure assessment. Risk assessment is a systematic process used to evaluate the potential adverse effects of chemical exposures. It involves determining the likelihood of harm occurring under certain conditions of exposure. Hazard identification focuses on understanding the toxic properties of the substance, while dose-response assessment examines the relationship between the dose and the severity of the toxic effect. Finally, exposure assessment evaluates how, when, and where exposure to the substance occurs.
