The role of an exposure scientist is that of relating "populations, communities, and ecosystems" to exposure to chemical, biological, and other "stressors," such as crude oil production toxic waste, for the purpose of measuring and modeling the "complex inter-relationship" between the two groups.
According to the National Research Council, 'exposure science links human and ecological behavior to environmental processes in such a way that the information generated can be used to mitigate or prevent future adverse exposures' (International Society of Exposure Science).
In the Ecuadorean Amazon crude oil contamination situation exposed in Crude, the role of an expert in exposure science could be to measure and model the inter-relationship between the human populations, the rainforest jungle ecosystems, and the wildlife affected by the Texaco/ Chevron oil production waste pits, oil spills, and leaks.
The task undertaken by an exposure scientist would relate to examining the exposure areas through one or more fields of specialization, such as environmental, physical, and biological, using exposure science "methods, measurements, models" to ascertain the effect of the exposure stressors on the environments in contact with them. These methods would generate information that might be used to "mitigate or prevent future adverse exposures."
