New Article in the Journal of Toxicology and Environmental Health

(NEW YORK, NY – August 31, 2015) – Ben Stanford, PhD has co-authored an article in the latest issue of the Journal of Toxicology and Environmental Health.

The article, titled “Evaluating Evidence for Association of Human Bladder Cancer with Drinking-Water Chlorination Disinfection By-Products” examines the relationship between disinfection byproducts (DBPs) and bladder cancer. Exposure to chlorinated DBPs is prevalent in populations where chlorine is used to disinfect public water supplies. Multifaceted research has been directed for decades to identify, characterize, and understand the toxicology of these compounds, control and minimize their formation, and conduct epidemiologic studies related to exposure.

This article summarizes the findings of an international workshop that was held to (1) discuss the qualitative strengths and limitations that inform the association between bladder cancer and chlorinated DBPs, (2) identify knowledge gaps for this topic in relation to chlorine/chloramine-based disinfection practices in the United States, and (3) assess the evidence for informing risk management.

The findings presented in this article indicate that there are strengths and limitations of evidence that will require additional studies to resolve and improve the understanding of exposure response relationships. In short, replication of epidemiologic findings with a more precise exposure assessment is needed to strengthen the knowledge base required to inform effective regulatory approaches.
