River scenario, where some data was easily obtained (i.e. water and air sampling), but exposure data was
more difficult, resulting in data gaps in the risk assessment framework. What are some of the challenges a
public health toxicologist might be faced with? You may discuss scientific challenges, as well as logistic issues
and challenges with public perception. As you consider these challenges, please also select one scientific
challenge and discuss how a public health toxicologist might mitigate that challenge. You may find it useful to
reference some of the concepts discussed in this module.
