The fourth and final course of the Impacts of the Environment on Global Public Health specialization will cover two topics. The first is environmental justice – that is, avoiding an inequitable distribution of environmental health threats in our population, and ensuring a healthy and safe environment and health equity for all. The second is risk assessment and management, a framework that can be utilized to assess and quantify human health risks, and to identify appropriate approaches to mitigating those risks and promoting better health. We will explore the steps involved in risk assessment, as well as how risk assessment can incorporate and address environmental justice issues.
