Researchers Search for Links Between Taconite and Mesothelioma
Monday, June 11th, 2007Citing an unusually high rate of mesothelioma among men in Northeastern Minnesota, a team of researchers from the Minnesota Department of Health is launching two new studies in attempts to determine whether or not taconite mining, popular in that region of the state, is linked to the deadly disease.
Minnesota Public Radio recently reported that the rate of mesothelioma in the northeastern part of the state is “much higher than it should be.”
Four years ago, a similar study noted that the most likely cause of that high incidence was “exposure to commercial asbestos.” Fourteen of the 17 miners who had developed mesothelioma at the time of that study had been exposed to asbestos as well as to taconite dust. Since then, another 35 taconite miners have developed mesothelioma.
“This is strong enough to more definitively look at commercial asbestos exposure and the taconite dust exposure,” says Mary Manning, director of health promotion and chronic disease at the state Health Department.
Manning says the studies will use case controls, which will compare several miners who didn’t get mesothelioma to each of those who did develop the disease. “They’ll try to compare exposure to both taconite dust and asbestos, to see whether taconite could be the likely cause of the disease,” she added.
Dr. Alan Bender is leading the study and will be working with other researchers from the University of Minnesota to compile the data. Scientists from outside the state will be asked to review study plans before they are implemented.
“This is going to be a major effort,” Bender says, “And we’re going to do what we can to answer as many questions as possible right now.”
