Environmental Speaker Series Luncheon
September 19, 2012
Speaker: Robert Golden, Ph.D., Founder of ToxLogic
Sponsor: This month’s luncheon was graciously sponsored by CTC Foundation.
Topic: The Linear No Threshold (LNT) Model — Time for Evidence-Based Cancer Risk Assessment?
Have you ever wondered why there is typically an outcry from some segment of industry following controversial EPA individual chemical assessments as part of the Integrated Risk Information System (IRIS) process [think dioxin or formaldehyde] or many Clean Air Act- and Safe Drinking Water Act-based regulations [think Mercury and Air Toxic Standards (MATS), or Stage 2, Drinking Water Disinfection Byproducts Rules (DBPR), etc.]? Did you know that EPA published a report on the costs and benefits of the 1990 Clean Air Act rules with the costs of compliance estimated at about $65 billion annually but the value of benefits estimated at almost $2 trillion? Did you know that a single regulatory default – the linear no threshold (LNT) model originally intended for cancer risk assessment, but now increasingly used for non-cancer effects as well, is the primary driving force behind all of the above? The history of the LNT, the lack of any scientific support for this default assumption, the regulatory and economic distortions created by this model and a process designed to challenge its continued use will be the subject of the September 19, 2012 EPG Luncheon Meeting.
Join us on Wednesday, September 19 at The Horinko Group’s offices in the West End of Washington, DC. To attend, please RSVP to email@example.com
