  a. Bacteria
  b. Aerosols
  c. Noise
  d. Burnout

Question 2

  a. Chemicals are not ordinarily found in the body tissues of the general population.
  b. Most chemicals have been studied to de-termine the effects of exposure on hu-mans.
  c. Chronic exposure to low-level doses of workplace chemicals below standards constitutes a potential health risk.
  d. Human effects of chemical exposure are associated with single agents rather than with the interaction of agents.

Answer to Question 1

ANS: C
Controlling physical agents, such as noise, can usually be accomplished through engineering strategies and personal protective equipment. It is much harder to change biological agents (bac-teria), chemical agents (aerosols), and psychosocial agents (burnout).

Answer to Question 2

ANS: C
It is true that chronic exposure to low-level doses of workplace chemicals below standards con-stitutes a potential health risk. Most chemicals have not been studied epidemiologically to deter-mine the effects of exposure on humans. As a consequence of general environmental contamina-tion with chemicals from work, home, and community activities, a variety of chemicals have been found in the body tissues of the general population. Predicting human responses to chemical ex-posures are complicated because multiple chemicals often combine and interact to create a new chemical agent.
