Since 1988, at least 58 miners from Minnesota’s Iron Range have died of mesothelioma, reports Jessica Van Berkel in a two-part series in the Minnesota Daily. Workers from these taconite mines also report high rates of silicosis, which is caused by dust from quartz or crystalline silica.

The University of Minnesota has received $4.9 million to study the possible link between mesothelioma and dust from taconite mining. Researchers have found spotty records of exposures in the mines, and miners don’t receive the results of the twice-yearly exposure measurements by the Mine Safety and Health Administration. And MSHA hasn’t updated its exposure limits for respirable dust containing asbestos and silica to make it more protective.
