Yeah, by this argument lead in the water isn't a concern.

You just made me mad by helping me realize that the Trump bros are going to break water by removing fluoride long before they fix water by removing lead.

Yeah but lead bioaccumulates where as fluoride/ine doesn't

Are you sure fluoride doesn't? It does accumulate in the soil, building up in crops. Considering fluoride exposure from all sources, many people are above upper safe limits, even from tea drinking alone

I don't think fluoride should be added to water as it just pollutes the environment, where 99.99% of water isn't coming in contact with teeth

It doesn't. This is high-school chemistry.

Fluoride only "accumulates" up to the peak concentration of the environment (no further) on places where it is removed from contact with that environment.

You can only accumulate fluoride in the soil if you keep adding it and there is almost no rain to wash it away.

Like how crops are irrigated with town water, and in many areas with lowering rainfall? Accumulates in fruit, vegetables, leaves too

[–] [email protected] 4 points 6 hours ago

Yes, irrigation with the minimum possible amount of water is known to destroy land for millennia at this point. But sodium will be a problem way before you notice any change in fluoride.

Yup, same with PFAS and forever chemicals. Maybe I'm ignorant because I'm not a doctor, but I don't know if this line of thinking holds water - pun not intended.
