Problem
A. Give two examples of non-dietary ingestion and explain how these exposures happen.
B. What is an infiltration factor? Name two things that may increase it and name two things that may decrease it.
C. How does the "proximity effect" factor into personal exposures in an indoor single-compartment chamber model?
D. Describe the concentration versus time curve characteristics of the step time and rectangular time functions within a one-compartment model. Name one pollutant source that behaves the same way as each type of curve.
E. What is a Monte Carlo Simulation and how is it used? Name one advantage in using such a model.
F. Name and describe two differences between indoor and outdoor pollutant modeling. Be specific.
G. What factors of a contaminant of interest require an aggregate exposure assessment? Name four compounds for which an aggregate assessment may be justified. What routes would be crucial for assessing exposure for each compound?
H. List at least two possible limitations to relying on models. Explain your reasoning.
I. What is the human exposure reduction act as described in the textbook? What is it meant to do? Do you think it would make a positive contribution toward limiting human?
