It's certainly bad for the companies that sell water bottles in plastic.
It would be interesting to see a comparison of water that is put into refilled plastic bottles versus the tap water that is transported in today's plastic water pipes. I venture to say that it wouldn't much different and that both cases would have negligible leached-plastic compounds.
- eurasiantiger 5y agoThe one thing that doesn’t get talked about is lead leaching from plastic pipes. You wouldn’t think that is a thing but it totally is.
- atatatat 5y ago> both cases would have negligible leached-plastic compounds. I was with you until this. This comment will not age well.
- simonblack 5y agoI probably wasn't clear-enough. After sufficient time has elapsed, the amount leached out drops further and further. After several years (a lot less than many plastic pipes' lifetimes) that amount of leaching will have dropped to very low levels. Just like radio-activity never actually drops to zero, but declines exponentially to negligible amounts after around 10-20 half-lives, I similarly see the same thing happening with plastic-leaching. As I said earlier, we don't appear to have had enough studies on the problem which look at things like plastic-leaching half-lives. As for not ageing well, I'm not either. <grin>
