Plastics

1 - PET/PETE (Polyethylene Terephthalate) - used for soda bottles, water bottles

Toxicity: "ok for single use"; According to a German study reported in March 2009 even single usage of this plastic is not ok. 78 percent of the water samples had detected "estrogenic activity".

2 - HDPE (High Density Polyethylene) - used for toys, milk jugs, liquid detergent bottles, shampoo bottles

Toxicity: one of the safest forms of plastic

3 - PVC (Poly Vinyl Choride) - plumbing pipes, meat wrap, cooking oil bottles

Toxicity: Avoid use! Contains phthalates which interfere with hormones; manufacture and burning is highly toxic releasing dioxin.

4 - LDPE (Low Density Polyethylene) - cling wrap, grocery bags, sandwich bags

Toxicity: one of the safest forms of plastic

5 - PP (Polypropylene) - syrup bottles, yogurt containers, diapers

Toxicity: one of the safest forms of plastic

6 - PS (Polystyrene) - disposable coffee cups, fast food containers

Toxicity: Avoid use! Styrene leaches into food causing cancer and hormone disruption.

7 - Other (usually polycarbonate) - baby bottles, water cooler bottles, stain resistant food storage containers, sports bottles, tin can lining, medical storage containers

Toxicity: polycarbonate contains BPA (very bad!) and is used in can linings; some #7s may be marked BPA free and might be made from starch (which is good and decomposes rapidly).
