A study revealed that some of the art and craft supplies being used by most Washington, D.C. area public school districts (City of Alexandria, Arlington and Fairfax counties--Virginia; Montgomery and Prince George's counties--Maryland; and the District of Columbia) contained toxic ingredients which could cause serious, long-term damage, sterility, and birth defects. Children are particularly at risk from toxic substances because their bodies are small and still developing. They often do not understand the dangers associated with a product and they have a tendency to put things in their mouths. Ingredients of each product were reviewed by the Center for Occupational Hazards. Products were placed in one of three groups; (1) should not be used in public schools; (2) should be used only in secondary schools; and (3) safe for use in all public schools. Three recommendations were made: (1) art and craft materials should be required to be labeled properly; (2) certain toxic materials should be eliminated from the public schools; and (3) training sessions concerning toxic art supplies should be required. Appendices include: "Art materials that children under 12 should not use, with substitutes"; "Text of Oregon House Bill 2992"; and "Products authorized to bear the CP Certified Products Seal and the AP Approved Product Seal of the Certified Products and Certified Labeling Bureau of the Art and Craft Materials Institute, Inc."
