Here it goes.... but this time.. a serious post... after a LONG research [thanks to all those research methodology classes, and my mam would be more than happy to know I have used it for my Blog ;) ]... And I would like to repeat, this post is made after referring to several sites and the information depends on those sites alone..
- #1 (PET or PETE) As already explained used for soft drinks, not recommended to refill. It's called Pet coz of the polyethylene terepthalate resin in it..
- #2 (HDPE) - High density poly ethylene used for milk bottles, shampoo etc, #4 (LDPE) Low density polyethylene used for squeezy bottles like mustard, and #5(PP) polypropylene are usually used for medicine bottles, are the ones generally considered to be safe.
- #3(PVC) very common plastic for pipes, and #6(PS) Polystyrene used usually for food service items such as cups, plates, etc., are generally considered to pose health risks and to be avoided. Though they are not used for water, they are used as food & beverage containers.
- #7(Others) It means this plastic is made using some other resin other than the 6 listed above. This is usually polycarbonate and has the risk of BPA( Bisphenol A) a harmful xenoestrogen that interferes with human hormonal messaging, which is reported to be the causes for the Breast and uterine cancers.
This BPA can also pose threat to children's developing systems, but the sad news is many of the plastic bottles for children like Sippy cups or baby bottles are of BPA containing plastics.. So try to avoid clear and hard plastic bottles, especially marked #7, or avoid plastic bottles altogether and use Glass bottles. There are glass bottles looking like plastic bottles available nowadays..So, now I understand you all wondering should we all stop using plastic bottles altogether? The answer is avoid it as far as possible, Use the safer ones like BPA free or #2,4 &5, and avoid using plastic in microwave eventhough they are microwave safe, as there are high chances of BPA leaching in food when cooked in microwave..
PLASTIC BOTTLES ARE NOT TOXIC BOTTLES IF USED SAFELY.. BUT TOXIC IF REFILLED OR REUSED WITHOUT PROPER KNOWLEDGE.
