The topic presents an introduction to toxicology as it is used in environmental health. The topic presents the basic principles of toxicology including toxicokinetics and toxicodynamics, and adsorption, distribution, metabolism and elimination of toxicants. Toxicants are examined by class (different types of toxicants), by system (the target organs they affect) and by population type (the susceptible populations most at risk of effect). Case studies are used to examine the pathways of exposure and health impacts of toxic chemicals. Risk assessment is presented as a tool to assess the hazard and exposure associated with specific toxins. The administrative and regulatory tools that are currently used in toxicology are also examined. The topic also considers the paradigms that underpin risk assessment and risk management strategies.
