Crayola takes the safety of our products very seriously and we were equally concerned by the report you saw about mercury in crayons. We subsequently had two independent, non-governmental labs test these same crayons using proper chemical testing protocols. Both test results reported no mercury in Crayola(R) Crayons.
In addition, we also worked with the manufacturer of the XRF testing equipment used by the author of the post you referenced to determine how and why her test showed the presence of mercury. They determined that the tests on our crayons showed a false positive for mercury, based on an interference created by another constituent of the crayons. In short - the information in the post is inaccurate. Based on these test results, we requested that the post be removed and a correction printed in order to prevent the further spread of inaccurate information and the unnecessary confusion of others.
So in defense of Crayola I printed their response and you can read the rest of the post with this information in mind....
Came across a post on Facebook and it could effect many people trying to keep heavy metals away from their children. The non-profit group Lead Safe America trying to prevent children from lead exposure in their home. Through a fluke accident Tamara Rubin was using a Niton XRF from Thermo Fisher Scientific to look for heavy metals. Her son happen to have his Crayola crayons with him so she thought she would examine them.
According to hear readings 20 out of the 24 pack of crayons tested fine. Four of the crayons showed high levels of mercury and low level of cadmium. These were Indigo, Blue Violet, Red Violet and Violet. Ms. Rubin was able to contact Crayola and they said the crayons were extensively tested and shown to be safe. If you want to be on the safe side and you know you have a child that like to eat or put crayons in their mouth the best bet is to just remove these crayons from the box. Better safe than sorry!
