Everything is Cancer: "Green" tungsten bullets may be carcinogenic
David Hambling at Danger Room
Over 90 million rounds of the "green" training ammunition has been used in the United States, since its introduction. It relies on a blend of tungsten and nylon, or tungsten and tin. That gives the bullets the same density and firing properties as the original, but without using lead. Tungsten was considered non-toxic. And, besides, it was believed that it was "non-mobile", unlikely to dissolve and travel, so it wouldn't get into the groundwater.
But new research by University of Arizona Research Professor of Pediatrics Mark Witten points to a different conclusion: that tungsten may elevate the risk for cancer.
