Low-Dose Toxicity

Controversy surrounds the claim that low-dose toxicity is a public-health problem requiring immediate regulatory intervention. Concerns include the low-dose effects of endocrine-disrupting chemicals, or hormonally active agents, which are the subject of ongoing EPA screening and testing. Through biomonitoring we now know that our bodies are “burdened” with traces of literally hundreds of industrial chemicals that have not been tested for health effects. For critics the question remains: are low-dose health effects “real”? This symposium, organized in conjunction with the Villanova University School of Law, explored the phenomenon of “low-dose chemical effects,” discussing ongoing regulatory efforts, the status of scientific research, and potential actions.
