3/24/10 In a review of more than 80 biomonitoring studies, the known endocrine-disrupting chemical Bisphenol A (BPA) was found in most of the samples taken from thousands of individuals from several different countries. These studies overwhelmingly detect BPA in individuals including adults, adolescents and children. Unconjugated BPA is routinely detected in blood (in the ng/ml range) and conjugated BPA in the vast majority of urine samples (also in the ng/ml range). In stark contrast, toxicokinetic studies propose that humans are not internally exposed to BPA. Some regulatory agencies have relied solely on only these toxicokinetic models in their risk assessments. Read the abstract from Environmental Health Perspectives.
