Tungsten carbide-cobalt (WC-Co) particles that are taken up by the body can be detected in the blood and are excreted via the urine.


For hard metal particles investigations on micro-size particles have been conducted for comparison. According to investigations conducted up to now, the assumption of differing modes of actions of nanoparticles compared to micro-sized material due to their small size has not been confirmed. The comparison of the biological effects showed merely differences in the effect strength [1]. WC-Co particles are likewise toxic, but exposure is nearly exclusively occupational and can be avoided by suitable protection clothes.
