Titanium is a silvery metal with a high luster and strength. It is used in many different industrial processes, as well as food, medical and electronics fields. Titanium is considered relatively bio-compatible and is used in medical and dental implants, but people who have these implants, as well as anyone who works with titanium, should receive regular testing to ensure that blood levels of this metal do not rise too much.

Poisoning from titanium exposure is most common in people who have artificial joints or dental implants that have been degraded by exposure to bodily fluids. As the surface of the implant breaks down, the titanium enters the bloodstream, where it acts like many other heavy metals, causing damage and eventually settling in the bones ad organs. 

Signs of overexposure to titanium can include eye or skin irritation, abdominal pain, problems with breathing and nausea or vomiting.
