You have now learned about the four primary approaches used to
estimate risk: field surveys, categorical
rankings, process models, and comparisons
of exposure and effects data. Before moving on to the next lesson,
try the following multiple-choice quiz to evaluate what you've learned
so far.
Instructions: Select the best answer based on the circumstances
described.
Which risk estimation
approach is most appropriate when exposure and effects data are
limited or are not easily expressed in quantitative terms?
Which method is most
appropriate for delineating exposures and effects found in natural
systems (as opposed to those found under controlled or prescribed
conditions)?
Which method of comparing
exposure and effects data is best for incremental quantification
of risks?
