Occupational-hazard study: Hardmetal workers can breathe easy

Workers in the hardmetal industry are not at increased risk for lung cancer or any of 63 other potential causes of death, concluded the largest and most definitive study on this population to date. The University of Pittsburgh Graduate School of Public Health-led study of more than 32,000 workers in five countries was performed after smaller studies indicated that tungsten carbide with a cobalt binder—the primary ingredients in hardmetal—may be linked to an increased risk of lung cancer. Hardmetal is a human-made substance second only to diamond in hardness. It's used in metal cutting tools and drill bits.
