7. Measurement internal exposure

Background
When chemicals are taken up in the human body, it is possible for certain substances to perform a measurement in biological matrices (urine, blood, hair, ...). This concentration canteach us something about the previous exposure during the last few hours, days, weeks, ... depending on the compound. In Belgium, a binding biological limit value is only available for lead (70 µg Pb/100 ml blood), but there are also a lot of other biological limit values that can tell us (in)directly something about the exposure in the recent or less recent past.
