Answer to Question 1

Ans: A

Both the toxicity of the substance and the expected exposure to the organism must be considered to define the anticipated risk. The prevalence, neurotoxic effect, and the amount in the environment are not considered primary in determining the anticipated risk.

Answer to Question 2

Ans: B
Pollutants generally exert greater influence on aquatic ecosystems than on terrestrial environments. Air pollutants can be carried by the winds; but once they fall to earth, they continue their transport along the waterways.
