Biological monitoring is the measurement of contaminant concentrations in the workplace. Is this statement true or false?

The statement regarding biological monitoring as the measurement of contaminant concentrations in the workplace is false. Biological monitoring specifically involves assessing the levels of contaminants or their metabolites in biological samples, such as blood, urine, or breath, rather than directly measuring the concentrations of the contaminants in the workplace environment. By analyzing these biological samples, it helps gauge the exposure levels of workers to hazardous substances and provides insight into the effectiveness of safety measures in place.

In contrast, measuring contaminant concentrations in the workplace typically refers to industrial hygiene monitoring, which involves direct measurements of airborne contaminants or other hazardous materials present in the workplace, using various sampling and analytical techniques. Each monitoring approach serves distinct but complementary purposes in ensuring worker safety and health.
