I just passed a coworker who had a coke that was nearing the point of explosion. I joked that I feared for her life. She saw that I had re-filled a plastic soda bottle (the same kind she had in her hand that was fizzing up) and said that refilling them with water is actually dangerous. She knew enough to say that plastics #7 and #1 were susceptible to leaching of plastic into bottles.

I googled around and found sites such as this one.

The claims all stem from the notion that a bottle in less than perfect condition will have small lesions that leak plastic. But when in the history of mankind has a bottle shipped from halfway across the country then filled into a vending machine which drops it 4 feet ever been in good condition? Wouldn't that make all bottles have this issue?

Is there any merit to this? Surely ATOT has debunked this, if it is debunkable?

Meanwhile I'll drink from my coffee mug which no doubt has caked on carcinogens from millions of cups of a drink made from the pitted, roasted, pounded, ground center of an unpalatable fruit.

Edit: Yep, it's pseudo-science. Now I just have to figure out the coworker's name so I can email her the link.

If leeching was a big problem, why would they use plastic bottles in the first place? Surely your coworker doesn't think that the coke originally inside the bottle is somehow immune to leaching the plastic?

If it is fact it's not worth worrying about the health risks...everything is going to kill you nowadays. Study this, study that, blah blah. Who the hell cares, you're still going to die.

Here is the snopes article. Kind of weak to quote a plastic bottling company to debunk the myth, but there appear to be other sites saying similar things about PET / DEHA

If snopes was really my friend they'd make their pages searchable :(

Uh....they are. I just did one and found the bottle article in my first try.

How is snopes not searchable? It took me less than 10 seconds to go to snopes, search for "reuse plastic" (without the quotes), and find this article..

Your co-worker probably saw this on the Today Show... I saw it as I was leaving for work this morning.
I still don't believe it. In fact, I'm drinking from a re-filled bottle of Fiji water right now~

It isn't pseudo-science but the threat may be overblown. Polycarbonate plastics (ex. most Nalgene bottles) do leach chemicals when exposed to high temps but the amount leached and the actual effects on the human body from the chemicals is unknown or up for debate. There is a concern however and it hasn't been shown that they do not have a negative effect. Children and the sick are more at risk than healthy adults.

i dont know how unsafe it is, and i think the safety factor re: bottles is generally overblown

i *do* however, taste the effects of reusing water bottles multiple time. leaching is definitely there
