This shows why backyard burning is such a dangerous and foolish thing to do. Backyard burning of PVC also gives off Hydrogen Chlorine, which forms Hydrochloric Acid in the lungs. This can result in serious lung damage and Pneumonia. We do not expect to find dioxin in PVC products at room temperature, although in fact we do occasionally find traces of it in products manufactured with less than ideal quality control. VCM is also a potent neurotoxin and carcinogen.
Manufacturers are reluctant to disclose information about products.
More and more toy manufacturers have been switching to the use of other materials. We had been getting these updates from Greenpeace, but they have not actively pursued these investigations for most of this past year. This may not be easy, since many of those using vinyl having been reluctant to provide this information. A careful study of our material would have answered all your questions.
