What are the two key concepts for this section? Define toxicology, toxicity, dose, and response. What are three factors that affect the level of harm caused by a chemical? Give three reasons why children are especially vulnerable to harm from toxic chemicals. Describe how the toxicity of a substance can be estimated by testing laboratory animals, and explain the limitations of this approach. What is a dose-response curve? Explain how toxicities are estimated through use of case reports and epidemiological studies, and discuss the limitations of these approaches.
