Multiple choice

What is the main limitation of biological monitoring in occupational epidemiology?

  1. It can only be used to measure exposure to a limited number of substances.

  2. It is expensive and time-consuming.

  3. It does not provide information on the route of exposure.

  4. It cannot be used to assess past exposures.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biological monitoring in occupational epidemiology is limited by the fact that it can only be used to measure exposure to a limited number of substances, and it may not be able to detect all potential exposure pathways.

Multiple choice

Which of the following is NOT a common type of health outcome assessed in occupational epidemiology?

  1. Cancer

  2. Respiratory diseases

  3. Cardiovascular diseases

  4. Mental health disorders
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mental health disorders are not typically considered a primary health outcome of interest in occupational epidemiology, as they are often difficult to link to specific workplace hazards.
