Question from ird
Does the plastic or metal leach when hot, cold, fridge cold, or freezer cold or just room temperature. Under which temperature condition is the leaching greatest? I ask this in regard to tea, lemonade(acid)and just drinking water from my clear hard plastic drinking cups. Also it takes time and money to replace these utensils and I would like to do this in time-affordable way that is safe. I hope you understand my question.

I love it when questions and responses both come in within days of each other.
Right before I received this question, another reader sent me this article about leaching, from Chemical & Engineering News: pubs.acs.org/cen/coverstory/87/8735cover.html.
The article says:
It’s an interesting article that gives many examples of the leaching of different materials, but for me, the key idea in the whole article is “What are the substances that are leaching, and what is their potential harm in humans?”
The article mentions leaching from glass, which many of us consider to be so inert. But I looked it up and glass does leach.
