Regardingthe risks of fluoride in GGG's mining, I want to put in perspective some of thebackground information you provide.
“1)hooper bay Alaska 21 to 23 may 1992level 100 ppm hundreds in hospital one dead reference Gessner et al 1994.”
Iimagine this is the article published in the New England Journal of Medicine1994 Jan 13;330(2):95-9.
If sothen your memory is faulty. It was indeed a nasty accident, caused by abreakdown of the fluoridation system.
Hundredsin hospital? No. Only one is mentioned as having been hospitalised.
Theamount of fluoride estimated was 150 mg per liter (i.e.150 ppm). The lower level you mention, of 100 ppm, is not in the article.

"2)los lunas new mexico 1980 at aschool reference hoffison r 1980"
https://fluoridealert.org/studies/acute06/
Thearticle was by Hoffman et al, not Hoffison.
Again,there was a breakdown in the fluoridation system. Concentrations were as highas 375 ppm. "The symptoms of patients in this outbreak were extremelymild."
Nevertheless theauthors correctly warn against "The recent introduction ofpleasant-tasting fluoridated mouthwashes containing concentrations of NaF from200 to 900 ppm."

"3)Mississippi1997 when the f content may have been as low as 40ppm reference penman1997"
Iguess you are referring to an article in Public Health Report (1997) Sep-Oct;112(5): 403–409.
Thefluoride content may indeed have been as low as 40 ppm in some restaurant andice samples, but what was the high ppm measured? It was water in a tap that wasmeasured at 200 ppm.
14people reported to the emergency department of the local hospital, but all weredischarged later than day.
“4) Iceland 1700 about two thirds of thelivestock and about a third of the population died of fluorine poisoning froman eruption.”
https://en.wikipedia.org/wiki/Laki
Thiseruption, in 1783, is very different from the previous cases. Laki spewed out afew million tons of hydrogen fluoride. Some deaths of humans and cattle were due to the fact that hydrogen fluoride produces a horribly corrosive liquid - hydrofluoric acid. As well, fluorosis of bones and teeth did many humans and animals.
"5)1994628 people were hospitalized for eating toothpaste."
Thispresumably refers to a report in the Journal of Public Health Dentistry.
https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1752-7325.1997.tb02966.x
Theperiod studied was 1900-1994. “While the outcomes were generally not serious,several hundred children were treated at health care facilities each year.”
************************
So, whileI don't deny that excess fluoride can kill, I doubt that anybody will drink GGG's tailings dam or obsessively lick their fingers after handling rocks at Kvanefjeld.
Inother words, I see little point in describing fluoride as deadly - as though we are talking of the Russian Novichok poison used in Salisbury, England.
