Taconite study finds worker's prolonged exposure ups lung risk
MOUNTAIN IRON,[url=http://www.christianlouboutindiscountmen.com/]christian louboutin discount[/url], Minn., April 13 () -- A five-year Taconite Workers Health Study indicates the more Minnesota workers spent on the job, the more likely they developed a rare and deadly lung cancer.Taconite, a hard, banded, low-grade ore, is mostly used in the iron and steel industry.The University of Minnesota research was designed to address the debilitating and deadly lung diseases by the needle-like fibers in commercial asbestos and dust from taconite ore. The study found each year a worker spent in the taconite industry, his risk of being stricken by mesothelioma increased by 3 percent, the Minneapolis Star Tribune reported. However, the $5 million study did not provide complete answer to the question that has been confronting miners and their families for decades -- did taconite dust exposure bear some blame for the lung illnesses? The researchers said at this point their research shows a possible link, but not a certain one. "Working longer times in the taconite industry does have risk associated with it -- that is an important finding," study leader Dr. Jeffrey Mandel, a physician and epidemiologist, said. Craig Pagel, executive director of the Minnesota Iron Ore Association,[url=http://www.jimmychoosaler.co.uk/]jimmy choo sale[/url], said industry officials would study the results in depth before commenting. The link between taconite and lung disease has been an Iron Range question for decades after needle-like fibers were discovered in Lake Superior and traced to the dumping of taconite waste rock 40 years ago. The researchers found 80 miners, all men, died of mesothelioma -- a rate nearly three times higher than the rest of the state's population. Commercial asbestos was once used widely in the taconite industry for insulation and other purposes and remains a prime suspect in the Iron Range cases, the researchers said.
