This is directly from the book I mentioned earlier called The Healthy Home Workbook. Thought it may be of interest to some of you.
You know how on the bottom of your pop bottles, tupperware, etc. there is a little number in a triangle? This is the list of what those numbers mean:
If the triangle contains a …
1 – Polyethylene terephthalate (PET) Soda and water containers, some waterproof packaing. Not recommended for reuse because difficult to clean and remove baacterial contamination. This type of plastic may also leach DEHA, a known carcinogen, when reused.
2- High Density Polyethylene (HDPE) Milk, detergent, oil bottles. Toys and plastic bags. Less toxic than many other plastics.
3- Vinyl/polyvinyl chloride (PVC) Food wrap, vegetable oil bottles, blister packages (some kids toys and soothers too!) Made flexible by use of phthalates (suspected carcinogen) and dioxin (known carcinogen) released during manufacturing and incineration.
4 – Low Density Polyethylene (LDPE) Many plastic bags, shrink wrap, garment bags. Less toxic than many other plastics.
5- Polypropylene (PP) Refridgerated containers, some bags, most bottle tops, some carpets, some food wrap. Considered safest.
6 – Polystyrene (PS) Throwaway utensils, meat packaging, protective packaging. Known to cause functional impairment of the nervous system. Styrene is carcinogen and a mutagen, highly toxic and may be leached into foods contained in polystyrene.
7 – Other. Usually layered or mixed plastic. No recycling potential, must be landfilled. Plastic labeled 7 is LEXAN or polycarbonate plastic and is used in water bottles purchased from sporting goods stores and in industry. Bisphenol A (BPA) linked to chromosome abnormalities in mice, chromosome damage and hormone distruption, can leach harmful chemicals in to the water.
Just a little FYI. So make sure that when you are buying teething toys and soothers especially for your babes that they are marked ‘No PVC’.
