Hot tea in plastic cups

AI Thread Summary
Drinking hot tea from plastic cups raises health concerns due to potential chemical leaching. While syndiotactic polystyrene has a high pyrolysis temperature, incomplete polymerization may leave harmful monomers in the cups. Studies indicate that plastics can release nanoparticles into hot water, suggesting that using plastic for hot beverages is not advisable. Some participants in the discussion prefer alternatives like glass or metal mugs, with stainless steel being highlighted as a safe option. Concerns also extend to potential toxins in metal containers, but stainless steel is generally considered safe. The conversation emphasizes the need for careful consideration of materials used for drinking vessels, especially when replacing plastics with alternatives like paper cups, which may also pose health risks.

TL;DR Summary
...Besides that, it was found that the plastic releases nanoparticles into hot water:
I feel some strange discomfort when I drink hot tea from plastic cups; I prefer drinking it from glass cups. Maybe this can be explained that the plastic dissolves in hot water, and it is harmful for health?
If I am not mistaken, the syndiotactic polystyrene has a temperature of pyrolysis about 260 Celsius, so this is not the explanation. However, the polymerization in technology is usually not full, and the plastic cup can contain some remains of a monomer; also, as I heard, the plastic usually contains some additions.

Besides that, it was found that the plastic releases nanoparticles into hot water:

So, I think it is not a good idea to drink hot tea from plastic cups. Is this problem described somewhere?
Maybe I should had created this thread in other section? But one of my questions is related to the harm of plastic for the health.

I tend to drink my tea from a metal LLBean camping mug. It retains the heat longer than a regular ceramic tea cup or glass cup.
You said camping mug I pictured this...

Also toxic heavy/reactive metals like Chromium, Lead, Mercury, Cadmium, Nickel, Zinc came to mind.

Click on your LLBEAN and it is made of stainless steel so you are good to go! ;)

Yet from the linked article:
This study shows that careful consideration needs to be done before the promotion of replacements for bio-hazardous products and environmental pollutants. We have been quick to replace plastics cups and glasses with disposable paper cups
Plastics still seems to be way better than cheap disposable.
 
I don't disagree. Sometimes, we throw the baby out with the bath water and replace him with an alligator.

I started to worry a bit there but then remembered its stainless steel.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
