I was away from the news for a while but thanks to some readers, I found out about a new study saying that #5 plastic (polypropylene) was discovered (almost accidentally) to leach two types of chemicals. The study is described in a little depth on the EWG website. It is not clear under which conditions the chemical leached -- was it the enzyme used in the experiment, was it under normal conditions?? -- and whether it is dangerous or not
This is very sad news especially because that are many foods wrapped into #5 plastic (considered safe) and most of these foods cannot be avoided. Even the medication is packed in #5 plastic containers. It is not easy to get rid of it; yes you can eliminate from your house everything that is made from plastic but you cannot stop buying certain foods whose nutritional value is very important for a healthy diet.
This type of plastic was considered safe until now; however even now nobody is arguing that it is bad, the study found that the plastic is leaching chemicals. But what chemical is safe? I do not believe in chemical safety. I would not be surprised at all if one day they will find that the other two types of plastic (#2 and #4) considered safe now will be found to leach chemicals.
