Mesothelioma and Asbestos reports that cobalt-tungsten is one of eight new chemical to join the US Department of Health and Human Services list of possible human carcinogens.
The market news is quoted as saying,
The eight new additions include “the industrial chemical formaldehyde and a botanical known as aristolochic acids… listed as known human carcinogens. Six other substances — captafol, cobalt-tungsten carbide (in powder or hard metal form), certain inhalable glass wool fibers, o-nitrotoluene, riddelliine, and styrene — are added as substances that are reasonably anticipated to be human carcinogens.”
