A landmark government study seeking to shed light on links between diesel exhaust and lung cancer in miners will be published in a medical journal next month, but only after a mining industry group has 90 days to review its findings, the Center for Public Integrity reports.
The decision stems from a judge’s ruling in June, which ordered two Department of Health and Human Services institutes to hand over the results of their research to the Methane Awareness Resource Group Diesel Coalition, a mining industry group that for years has contested the need for the study.
The study, which focused on more than 12,000 current and former employees from eight different mines, is much anticipated by public health officials. According to the Center for Public Integrity, its goal is to determine whether ultrafine diesel particulate matter — a component of exhaust from diesel-powered machinery — poses a serious hazard to miners in confined spaces.
A review of workers at mines that produce commodities other than coal, the study was launched in 1995 to expand on research that suggested a link between diesel and lung cancer in truck drivers and other workers. The study’s results will offer a “state-of-the-art evaluation of diesel,” said Kyle Steenland, a professor at Emory University’s Rollins School of Public Health and a former federal epidemiologist.
Many health experts, however, are dismayed by the decision to hand the study over to the mining industry first.
“This is the only example I know of where an industry group gets access to the information before anybody else does,” said Celeste Monforton, a professor at George Washington University and former regulatory official. “I think as soon as the study is published [industry consultants] will already have another paper prepared that will dissect it and explain away any risks that are identified.”
The mining industry’s lawyer says that his only goal is to learn more about how the study was conducted so as to convey that information to his clients and the workers, not to prepare a thorough response to any negative conclusions.
