Risk Characterisation for Human Health

10 Units

Many areas of the world have contaminated sites as a result of anthropogenic activities. With 60% of such contaminated sites located in the urban environment there is significant potential for human exposure to contaminants. For this reason, remediation of contaminated sites is legislated as a necessity prior to rehabilitation or redevelopment of such sites. Current process for the assessment and remediation of contaminated sites requires a detailed assessment of risk contaminants pose to both environment and human health. It is best to follow the risk based approach to managing contaminated sites. Currently developments in risk assessment provides fundamental information to better understand the dynamics, fate and mechanisms of contaminants. The aim of this course is to provide students with the history, concepts, principles, practice and statistical skills, models and future directions in exposure assessment and toxicity assessment of risk characterisation, as well as involved uncertainties.
