Abstract
Biological monitoring is the estimation of exposure to an agent through the measurement of biomarker(s) resulting from an internal dose of an agent. The biomarker(s) are typically the agent or its metabolite(s) in a biologically derived specimen. For example, styrene in expired air, styrene in blood, and mandelic and phenylglyoxylic acids (metabolites of styrene) in urine. The biomarker also can be a highly specific, validated effect of the agent, such as elevated levels of zinc protoporphyrin in blood caused by exposure to lead. Due to advances in molecular biology, genetics, analytical chemistry, and other basic sciences, it is now possible to detect smaller amounts of analytes and contaminants and smaller biological changes, as well as to identify mechanisms at the cellular and molecular levels. These advances can be exploited for biological monitoring, in some cases. Legacy biological monitoring, is the measurement of a specific biological monitoring determinant which contains none of the atoms of the molecule to which the organism was exposed. The most common example of this is an antibody produced against small molecular weight molecules or altered constituitive proteins. Numerous investigators have implicated putative exposure to macrocyclic tricothecenes and other compounds from Stachybotrys chartarum as being associated with a plethora of signs and symptoms of disease. To date, no compelling biological marker for exposure to Stachybotrys chartarum mycotoxins or other metabolites has been presented. There is no doubt that exposure to Stachybotrys chartarum is associated with an increased prevalence of self-reported symptoms. However, evidence of the association of these complaints with frank disease is lacking. More biological monitoring research is needed to solidify these associations, if present.
