I'll take microplastics over lead any day.

The dose makes the poison.

I'd choose micro plastics vs an equivalent mass dose of lead.

If it was 1000x the amount of micro plastics vs lead it's maybe less obvious which is the less bad poison. I'd have to do some research at that point.

I think framing it this way it's obvious that lead is worse than micro plastics. But when you go from lead soldered copper pipes to PEX I don't know what the doses you get from each are.

I think its very obvious 1000x microplastics is much better than the lead.

Maybe if you said a billion times.

Okay what's the safe dose of micro plastics? What's the evidence for that dose being safe? Do we have 100 years of data?

The reason we know there isn't a safe dose of lead is a lot of study.

Every month there's a new study about some crazy micro plastics things where they got found in some new place. We're in the early days of figuring out how bad it is. We don't really know yet.

Sure, but (maybe someone can jump in here) isn't copper pipe + water soluble lead-free flux + lead-free solder better? Copper piping is more expensive--dunno when you'd make your money back over tap filters, but broadly I don't think you have to choose between lead and microplastics in your water from your piping.
