Which statement about chemical agents is accurate?

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.
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.
