Eli5 how do micro-plastics end up in our bodies from things like bottles and plastic packaging

Question

I have been googling how micro plastics get into our bodies and I get a lot of articles saying it’s from drinking and eating from plastic but nothing explains HOW the micro plastics are actually leaving the containers and getting into us. I specifically want to understand how drinking out of a plastic bottle transfers plastic to our body? I understand microwaving plastic leaches chemicals into food but I don’t get how drinking cold water from plastic could transfer the micro plastic to our bodies.

Answer 1

Drinking water from a plastic bottle does exposed you to microplastics. It’s not a huge amount, but is you for whatever reason only drink bottled water, plus combined with other sources u/daysofbreeze mentioned, it can be significant.
