EHS505 · Unit 2: EXPOSURE ASSESSMENT AND DESCRIPTIVE ANALYSIS

In this unit you will learn about exposure assessment in environmental epidemiology. This is an attempt by environmental epidemiologist to assess the level of exposure of pollutants to the environment and its impact on public health.

What you should be able to do

  1. Define environmental epidemiology and its core concepts
  2. Apply exposure assessment methods to evaluate environmental hazards
  3. Conduct risk assessments for air, water, and soil pollution
  4. Investigate disease clusters using epidemiological techniques
  5. Interpret scientific evidence related to environmental health hazards
  6. Utilize statistical packages for data analysis in environmental studies
