barium in excess of the allowable limit.

Why is barium even present in a toy manufactures facility? What purpose does it have?? When I looked up Barium in Wikipedia I see it is used in glassmaking, rat poisions, used for drilling oil wells, it gives fireworks their green color, but no where could I find why it would be present on a WOODEN TOY FOR TODDLERS. If someone could explain to me, please do so.

So when are parents going to wake up and see that these Chinese manufactures do NOT have our children's best interest at heart. How many tainted toys are going to be enough for everyone to stop buying these products?? Maybe we need to change the word 'tainted' to something more accurate like 'potentially lethal', maybe that will get peoples attention.
