This module will give students a grounding in the scientific process behind chemical risk analysis. The effect of chemicals in the environment will be observed and explained. Concepts such as dose-response relationships and observed-effect levels, as well as modes of entry and routes of exposure to humans, biota and the ecosystem as a whole, will be examined.
A large part of the module will be dedicated to understanding quantitative exposure assessment, which will include the introduction of fate modelling and the prediction of chemical concentrations in different environmental compartments. Students will also be familiarised with current assessment procedures for chemical registration and will partake in group practicals/workshops to understand the steps in chemical risk analysis. They will perform their own chemical risk assessment procedures, learn to use simulation models to predict outcomes, and will understand the role of risk assessment in decision making.
Please note, this is a core module for the Pollution pathway.
