1.   Polycarbonate plastic products contain Bisphenol-A (BPA), a chemical linked to cancer, slowed metabolism, hyperactivity and birth defects. When possible, avoid plastics with the #7 in the recycling logo, and refrain from putting plastic food and beverage containers with the #7 in the microwave, freezer or dishwasher.

2.   Compact fluorescent light bulbs (CFLs) contain trace amounts of mercury. Be sure to properly recycle them. Do not throw them in the trash, as they can release mercury into the environment.

3.   Metal toys and children's jewelry too often contain cadmium, a known carcinogen that is linked to developmental problems and osteoporosis. Either avoid purchasing metal toys or try to keep children from chewing on toys or jewelry that contains metal.

4.   Foam furniture is a major source of exposure to flame retardants that are connected to cancer, developmental and reproductive problems. Try to only buy foam products made in the U.S. after 2004, and don't re-upholster older foam furniture.

5.   Children's lunchboxes and backpacks may still contain phthalates (which have been banned from children's toys). The chemical is linked to liver cancer, birth defects, and infertility. Look into buying products labeled PVC-Free.

6.   Non-stick cookware emits toxic fumes when overheated. Chemicals that make up Teflon are associated with smaller birth weight and size among newborn babies, increased cholesterol, and weakened immune defense against disease. The safest move is to use cast iron or stainless steel pans. Otherwise, avoid overheating or preheating non-stick cookware, and make sure to turn on the exhaust fan.
