supposedly have even official effect as it is argued for fluoride that you don't have the studies to back it up is going beyond the purpose of a public water system is going to to to not be paying attention to the fact that we have normal sector of the population being adversely affected by these chemicals for water supply is i think giving this city a risk  system and then the method of action is not through ingestion so to force everyone to take an uncontrolled dose of this in its own control because everyone's drinking different amounts of water is is  creating a problematic way to apply this treatment it would be better here it's unnecessary for public health to do it this way it would be better for dentists to prescribe it for their patients if that's what they  need and in doing so mass medicating the population of the city it is putting itself at risk in a lot of different ways and one of which i just want to point to is an environmental justice perspective in care as those  our community there are laborers are consuming greater quantities of water when they're doing their work and so they're overexposed more so than the rest of us so that's a real concern as well so i know the mechanism by which it gains entry into the bloodstream and turned into about fifty percent of the trans in the stomach ph and that is fully assimilated because it's about the size of a water molecule and what happens is the blood level in one ppm is about point two parts per million and four crosses the blood brain barrier there's absolutely no scientific doubt about that now with all we now have the ready study in two thousand and eleven we have the that one hundred twenty eight studies have shown the effectiveness of for additional in preventing cavities apparently references came from the poster not up just for you w h o meaning portraying references from  this is very significant because during the years the studies were done cavities were decreasing all over the world please take a look at this right here these two are cavities decreasing all over the world where the countries are florida are not about something else fifty one of the reports were very poor scientific quality such a short reports and state internal newsletters were journals or state department newsletters progress reports personal communication forth the reports could not be verified at all none of the last nineteen showed in any scientifically acceptable manner for additions affected one hundred twenty records or destroyed no real scientific and when i have given you the references of what i'm talking it showed not only no benefit from florida but actually a twenty seven percent increase in k for every one point of the early in the floor  science that supports claims that for additional benefits the team no matter what government the united nations or professional organizations in support of the purpose there are very many high quality research papers waste the e p a even said that they were one of the best ways to get rid of this toxic waste the solution to pollution is dilution just put it in the water so it has other hands yes there are two basic  article saying that there was up to sixteen hundred parts per billion left in the drinking water in seattle schools that's one point six parts per million that's twice the fluorite level so the reason is that water up there pristine great drinking water with four i'd put it but it only had like ten parts per million south for protection so when the factory was dumping the forest of the columbia river the salmon tried to navigate upstream
