Biological monitoring involves measuring chemicals or their metabolites in biological specimens such as blood, urine, or breath to assess exposure to hazardous substances in the workplace. This process helps evaluate the absorption, distribution, metabolism, and excretion of chemicals within the body, providing a comprehensive assessment of an individual’s exposure to potentially harmful substances.

Having and using biological monitoring in the workplace is important for several reasons. It provides direct evidence of chemical exposure, allowing for a more accurate assessment of potential health risks compared to environmental monitoring alone.

This information helps in identifying workers at risk, evaluating the effectiveness of control measures, and ensuring compliance with occupational exposure limits and safety regulations. Additionally, biological monitoring supports early detection of adverse health effects, enabling timely intervention and preventive measures to protect worker health. By implementing comprehensive biological monitoring programs, organizations demonstrate their commitment to maintaining a safe and healthy work environment, fostering trust and responsibility among employees.
