Biometrics is applied in toxicology through various methods: 1. Dose-Response Modeling: This involves understanding the relationship between the dose of a toxicant and the biological response. 2. Epidemiological Studies: Biometric techniques are used to analyze data from population studies to identify trends and correlations related to toxin exposure. 3. Risk Assessment: By analyzing exposure data and biological effects, biometrics helps in assessing the risk posed by toxic substances.
