Wait. the main mechanism of concerns from microplastics is the body is from leaching of toxic chemicals once in the body. Wouldn't boiling increase the leaching of the chemicals into the water up front?
I think the idea is the calcium carbonate traps it but not sure why or how efficient it is. Or if you boil microplastics do they melt (become petrol or oil?) or do they stay intact or a mix.
The most commonly encountered plastics (Polyethylene, and Polypropylene) don't leech anything. It's mostly vinyl that leeches, and that's not a common microplastic.
