What is Human Biomonitoring?
Human Biomonitoring is a scientific technique for assessing human exposures to environmental agents and their effects, based on sampling and analysis of an individuals tissues and fluids. While blood, urine, breast milk and expelled air are most commonly measured, hair, nails, fat, bone and other tissues may also be sampled. This technique takes advantage of the knowledge that environmental agents that have entered the human body leave markers reflecting this exposure. The marker may be the agentl itself or a breakdown product, but it may also be some change in the body resulting from the interaction of the agent or its breakdown product(s) with the individual, such as alterations in the levels of certain enzymes or other proteins which may lead to modifications of normal body processes.
