Wikipedia says that:
Research is ongoing as to whether plastic water bottles can leach hazardous chemicals into the water, especially when heated.
And I know it's now fashionable for vendors to tout how their bottles are "Bespinol-A free (BPA-free)". But the manufacturing of plastics involves all sorts of toxic compounds and elements, regardless of BPA. So, I was wondering - what other compounds might leech from plastic bottles, and what can I do to avoid that or mitigate it?
Of course, a possible answer is "don't use plastic bottles", but let's assume that I am, and I want to either do something with my existing one or get a safer/more resilient one.
Note: I already know I should avoid increasing the risk by heating the bottle or keeping it in the sun.
