SOME CONFOUNDING VARIABLES
1.) Many householders in fluoridated areas have made other arrangements for clean fluoride free drinking water, and need to be excluded.
(From ABS 2013 data, 9.9% of Aussies use rainwater and 6.5% use bottled water as their main source of water. But 32.4% of Aussies have water filters, and about one quarter of these may be fluoride filters.)
2.) Rodents are much used as lab. animals, they manufacture Vitamin C, which means they need larger doses of fluoride to damage or kill them. Unlike us humans who must obtain Vit. ‘C’ from our diets. (Most humans are deficient in “C’ which is made worst with fluoride exposure. ) Guinea pigs are a better choice for biomedical research. They may be more expensive to keep. They have provided essential information to support research, and like us humans they cannot produce Vitamin C and need it supplied in their diet). – if we must use animals for experiments.
3.) Residents moving between fluoridated and non-fluoridated areas before trials need to be identified and excluded. Fluoride damage for some people can take time, often many years. However some humans are very sensitive and will react to fluoridation in days. (Fluorosis of teeth will only be visible if fluorides are present at the time of tooth formation.)
4.) Workers moving between fluoridated and non-fluoridated areas on workdays need to be identified and excluded. – Some may take flasks to work; others may buy drinks at work.
5.) Food and drink, commercial and domestic, moving between fluoridated and non-fluoridated areas will interfere with results. This will mostly be soft drinks, beer, and wine. (Grapes are often sprayed with fluoride containing agricultural sprays).

6.) Unequal distribution of fluoridated water throughout city water mains. – Water engineers have raised this issue from the first proposal to add fluoride to drinking water. The inability to control individual doses renders the notion of an ‘optimum concentration’ a scientific nonsense.
7.) Unrecognized difference between natural and artificial fluorides. Calcium fluoride occurs naturally, it is a problem as evidenced in many parts of the world, but the calcium acts as a buffer and renders it less injurious – but not harmless.
8.) People living at the end of a dead end streets: No explanation seems to exist, but readings especially after low or non-use periods (night time) have high/er readings of fluoride.
9.) Different dietary habits and nutrient status of residents: Body weight, infant formulae mixed with fluoridated water, rather than breast milk for babies, are more complications. Fluoride-pregnant women!
10.) Climate, weather, geographic latitude and elevation cause large water consumption variations.
11.) Heavy manual labour resulting in higher water consumption, can be yet another variation. The NHMRC in 1954 was deeply concerned over cane cutters because of their high water and tea consumption due to the risk of Fluoride storage disease (Tea is high in F.).
In Australian mines – there have been a number of studies that the present NHMRC and FSANZ are desperate to avoid. “The average fluid consumption per shift was 6.48 liters (over this mix of different shift lengths) with a standard deviation of 2.41 liters and range of 2.40 to 12.50 liters.
12.) Genetic background – e.g. Negro and Australian aborigines are more sensitive to fluorides, (low kidney function). More → HERE
13.) Contaminants in the fluoride chemicals see separate list below…
14.) Pets need clean water too! Dogs receive extra fluoride doses in some flea treatments: ‘FRONTLINE’ contains Fipronil ⇔ Fluoride Dangers: What’s In Your Dog’s Water?
15.) Variations of water pipes: New or old, lead, concrete, cast iron, polythene, copper, stainless steel, and mixed lines. New concrete lined pipes absorb fluorides for some time. Lead pipes and solder joints will release lead in a fluoride environment.
16.) Fluoride pollution from power stations, industry and vehicles and occasionally volcanoes:
Air: fluoride releases from industry, Anthropogenic sources of atmospheric fluoride can result from coal combustion by electrical utilities and other industries.
Releases can also occur from refineries and metal ore smelters, aluminum production plants, phosphate fertilizer plants, chemical production facilities, steel mills, magnesium plants, and brick and structural clay manufacturers, as well as copper and nickel producers, phosphate ore processors, glass manufacturers, and ceramic manufacturers.

17.) Living near the ocean has the advantage of providing some iodine from the sea air which will help overcome the reduced iodine effect that fluoridation creates.
PFOS, PFOA, PFNA, PFAS, PTFOS, PFOA, PFHxA and PFBS etc. are contaminants only recently being acknowledged.
20.) As evidenced above, so many factors make scientific assessments of the benefits or otherwise of fluoridation impossible to tabulate.– All the ‘Fs’ Are Code for Fluoride. – Fluoride is a “Protected Pollutant” and it will only appear in the mainstream media when it is being promoted.
As can be seen by the list of variables above, research into fluoridation, in the
field, the library, the laboratory or via statistics, requires much knowledge.
Many previous research outcomes have been compromised by
poor designs which have ignored some of the above.
Fluorides are extremely reactive, variables
dangerous and in many ways are
a little unpredictable.
WITH A VARIETY OF TOXIC CHEMICALS:
Fluosiloxanes, Aluminium, Iron, Arsenic,
Beryllium, Cadmium, Nickel, Lead
Mercury, Chromium, Sulfides,
As can be extrapolated from the above, in all situations
the harm done by fluoridation is probably greater
than current research would suggest.
