Last night Trace and myself had a wonderful evening chatting to old and new friends at the VPF Ball http://www.vpf.org.uk/ and one topic that first emerged amongst the group was that of the safe use of plastic bottles. So I thought I would put a post up on the issue first thing. Here goes…the news about plastics has been pretty alarming, causing some of us to go dashing for the water bottles to see what kind of plastic they are—and find out if we’ve been unwittingly poisoning our children and ourselves with chemicals leaching into the water from them. Here is a handy chart that identifies the good, bad, and OK plastics and where they are found:
1 Polyethylene terephthalate (PET or PETE)
Used to make soft drink, water, sports drink, ketchup, and salad dressing bottles, and peanut butter, pickle, jelly and jam jars. GOOD: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones.
2 High density polyethylene (HDPE)
Milk, water, and juice bottles, yogurt and margarine tubs, cereal box liners, and grocery, trash, and retail bags. GOOD: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones.
3 Polyvinyl chloride (V or PVC)
Most cling-wrapped meats, cheeses, and other foods sold in delicatessens and groceries are wrapped in PVC. BAD: To soften into its flexible form, manufacturers add “plasticizers” during production. Traces of these chemicals can leach out of PVC when in contact with foods. According to the National Institutes of Health, di-2-ethylhexyl phthalate (DEHP), commonly found in PVC, is a suspected human carcinogen.
4 Low-density polyethylene (LDPE)
Some bread and frozen food bags and squeezable bottles. OK: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones, but not as widely recycled as #1 or #2.
5 Polypropylene (PP) Some ketchup bottles and yogurt and margarine tubs.
OK: Hazardous during production, but not known to leach any chemicals that are suspected of causing cancer or disrupting hormones. Not as widely recycled as #1 and #2.
6 Polystyrene (PS)
Foam insulation and also for hard applications (e.g. cups, some toys) BAD: Benzene (material used in production) is a known human carcinogen. Butadiene and styrene (the basic building block of the plastic) are suspected carcinogens. Energy intensive and poor recycling.
7 Other (usually polycarbonate)
Baby bottles, microwave ovenware, eating utensils, plastic coating for metal cans. BAD: Made with biphenyl-A, a chemical invented in the 1930s in search for synthetic estrogens. A hormone disruptor known to simulate the action of estrogen when tested in human breast cancer studies. Can leach into food as the product ages.
