I wrote earlier about how consultants for PG&E published a fraudulent article exonerating chromium-6. The Journal of Occupational and Environmental Medicine is now publishing a retraction of the paper. From the EWG press release:
The July issue of the Journal of Occupational and Environmental Medicine (JOEM), the official publication of the American College of Occupational and Environmental Medicine, will carry a retraction of a 1997 article published under the byline of two Chinese scientists, JianDong Zhang and ShuKun Li.
The article appeared to be a reversal of an earlier study by Zhang that found a significant association between chromium pollution of drinking water and higher rates of stomach cancer in villages in rural northeast China. Since its publication, the fraudulent article has influenced a number of state and federal regulatory decisions on chromium.
“It has been brought to our attention that an article published in JOEM in the April 1997 issue by Zhang and Li failed to meet the journal’s published editorial policy in effect at that time,” says the retraction, written by JOEM Editor Dr. Paul Brandt-Rauf and obtained by EWG. “Specifically, financial and intellectual input to the paper by outside parties was not disclosed.” …
PG&E hired ChemRisk to conduct a study to counter Hinkley residents’ claims of cancer and other illnesses from chromium-6 in their water. ChemRisk tracked down Zhang, a retired Chinese government health officer, and paid him about $2,000 for his original data. ChemRisk distorted the data to hide the chromium-cancer link, then wrote, prepared and submitted their “clarification'” to JOEM under Zhang and Li’s byline, and over Zhang’s written objection.
Zhang has since died. But JOEM located his co-author, ShuKun Li, who agreed that the article should be retracted.
