BPA is a terribly harmful chemical, but a $10 billion industry stands in the way of banning it for good.
Plastics To Avoid – recycling codes – 3, 6, and 7.
Most plastic products are marked with a number that corresponds to the type of plastic it is made of. The number, known a as ‘recycling code,’ can be found within the triangular recycling symbol (see below) that recyclable plastics are marked with.
The plastics you want to avoid are numbers 3, 6, and 7 – these are the types that can release nasty hormone disruptors and carcinogens into your food and drink.
#3 Polyvinyl Chloride (PVC) has di-2-ehtylhexyl phthalate (DEHP). DEHP is an endocrine disruptor and a likely human carcinogen.
#6 Polystyrene (PS) likely will leach styrene – which is another possible endocrine disruptor and probable human carcinogen- into your drink or food.
#7 Polycarbonate contains bisphenol-A, a the hormone disruptor. This chemical can leach out when it is heated or exposed to acidic solutions. This type of plastic is very common in sports bottles and is used in most baby bottles and 5-gallon water jugs – watch for this one!
