Which monitoring approach measures environmental agents in the workplace to assess exposure risk?

• A. Health surveillance
• B. Environmental monitoring
• C. Biological monitoring
• D. Medical surveillance

Answer: (B)

The main concept here is assessing exposure risk by measuring the workplace environment itself. Environmental monitoring directly measures the presence and concentration of hazardous agents in the workplace—air, surfaces, or other media—to determine if exposure levels are within safe limits and whether controls like ventilation or PPE are effective. This approach provides a direct picture of the external environment and the potential dose workers are exposed to, which is why it’s best for evaluating exposure risk. Health or medical surveillance focuses on workers’ health status or internal dose, not on the environmental levels. Biological monitoring looks at substances inside workers’ bodies to estimate absorbed dose, again reflecting what happened after exposure rather than the environment itself.
