theo colborn and toxicology

I'd speculate that Colborn's frustration with toxicologists is not particularly personal, but that her beef with toxicology is primarily about both the assumption that "the dose makes the poison" (a precept that looks for greater impacts correlated with larger-magnitude exposures) and the risk assessment model on which much of toxicology operates. The work of several people in the ED world indicates that dose is not only NOT the only factor -- and, indeed, sometimes small dosages seem paradoxically to cause effects that larger doses do not -- but that effects can begin prenatally and unfold at various developmental moments. These discoveries represent an alternative reality to the traditional view of toxicology -- that a substance can be identified, isolated, and causally either linked or not to an outcome -- and suggest lenses through which toxicology does not typically view data. These kinds of phenomena turn the risk assessment model on its head.On Environmental scientist Theo Colborn warns about the chemicals all around us posted 2 years, 3 months ago 6 Responses
