Mercury

Mercury is used in inks, adhesives, and as a catalyst in reactions to form polyurethanes (ATSDR 1999). HealthyToys.org detected low concentrations of mercury in a number of different toy components. Mercury can exist in different forms and some forms are more toxic than others. Methylmercury is a form of mercury that is particularly hazardous to the developing brain. The main pathway of exposure to methylmercury is from eating contaminated fish and it is unlikely that this form would be present in children's toys. However, the use of mercury in children's products means potential exposure of workers to this compound and release to the environment when the product is discarded.

Health Effects:

Mercury is a persistent toxic chemical that can build up in the body.
All forms of mercury can affect the kidneys (ATSDR 1999)
Inorganic mercury is also toxic to the nervous system.
