Problem: Many homes built before 1978 contain lead paint, which exposes contains a toxic heavy metal. This paint can be found on window frames, walls, old cribs and in new, imported toys and jewelry.

Solution: Use low- or zero-VOC (volatile organic compound) paints with natural pigments such as clay. These new paints are durable, cost-effective and less harmful to human and environmental health. Leave lead-based paint undisturbed if it is in good condition; do not sand or burn off paint that may contain lead. Use a lead test kit to identify places and household objects where lead is lurking.
