Microplastics and pfa's contaminate much of the food supply too.

Fluorine is a menace. The reason it's used so much is that about 1/3 of the supply of phosphate comes from fluorapatite. The sulfuric acid treatment yields a mix of HF and H2SO4 and calcium, and even better, this means that most gypsum, ie, calcium sulfate, used in household interior plasters, is contaminated with hydrofluoric acid.

The epidemic of bipolar disorder and slow metabolism is mostly caused by fluoride poisoning the thyroid. 

 Yep! Even the US government recently admitted current fluoride levels were making less intelligent to a detrimental degree. 

 Oops. I read Fluoride 😆  

 Hydrofluoric acid is fluoride but PFAs are where you take hydrocarbons and reduce the hydrogens off and substitute with fluorine. So technically PFAs contain fluorine. But fluorine is aggressive stuff and will eat almost everything, it has the highest pka and can drive even sulfur off stuff, which is otherwise the most resistant acid ion in salts... IE, if you get HF and put it on gypsum it forms calcium fluoride and sulfuric acid.
