Current risk assessment approaches underestimate chemical toxicity

Scientific review shows that some chemicals are proportionately more toxic at lower exposure levels; “dose makes poison” principle indicates that current risk assessment approaches underestimate chemical toxicity. In an article published on December 19, 2017 by news provider Environmental Health News, journalist Brian Bienkowski reported on a new scientific review addressing the toxicity of chemicals and the applicability of safe levels. The review was published on the same day in the peer-reviewed journal PLOS Biology and conducted by Bruce P. Lanphear from the Faculty of Health Sciences, Simon Fraser University, Canada.

Lanphear reviewed studies on some of the most common and extensively tested chemicals and pollutants, including radon, lead, airborne particles, asbestos, tobacco, and benzene.
