I've noticed no difference anywhere. In fact, I was thinking just this morning about catalog shopping. In the one I was looking at, they had children's clothing and jewelry - the same stuff I've seen people here wonder about. I'm looking at a catalog from a major retailer right now, and everything on these two pages is made from polyester, plastic and/or polypropylene. As the manufacturer and retailer of the products, this company would be responsible for testing, I assume. Apparently they're not worried about these materials. Good for them.
