There are about five popular pool sanitation methods, but the two most common are chlorine and salt. Salt Water Pools Contrary to popular belief, it is important to realize that a salt water pool IS a chlorinated pool. By having a saltwater pool system, you are not eliminating chlorine from your pool, rather you are electrically converting pool salt into chlorine.
The Australian government states that water fluoridation is the most effective means of achieving fluoride exposure that is community-wide. Surgeon General the American Public Health Association the Royal Commission on the National Health Service Australian Medical Association New Zealand Medical Association Health Canada supports fluoridation, citing a number of international scientific reviews that indicate "there is no link between any adverse health effects and exposure to fluoride in drinking water at levels that are below the maximum acceptable concentration of 1.
This is because there is clear evidence that optimal concentrations of fluoride provide protection against cavities, both in children and in adults. I mean, when the U. But when we looked at the studies that have been done, we found that many of these questions are unsettled and we have much less information than we should, considering how long this [fluoridation] has been going on.
In the face of ignorance, controversy is rampant. Three such outbreaks were reported in the U. Issues studied have included fluoride concentrations in groundwater and downstream rivers; lawns, gardens, and plants; consumption of plants grown in fluoridated water; air emissions; and equipment noise.
The review found that the evidence was of moderate quality: Although no major differences between natural and artificial fluoridation were apparent, the evidence was inadequate for a conclusion about any differences.
Fluoridation may be useful in the U. This perspective suggests it would be unethical to withhold such treatment.
The balance of benefit to risk ratio - is unclear due to the lack of good evidence for or against water fluoridation. Alternatives to the practice exist - topical fluoride therapy toothbrushing etc. The role of consent- It gets priority when there are potential harms.
The report therefore concluded that local and regional democratic procedures are the most appropriate way to decide whether to fluoridate. Media reporters are often poorly equipped to explain the scientific issues, and are motivated to present controversy regardless of the underlying scientific merits.
Websites, which are increasingly used by the public for health information, contain a wide range of material about fluoridation ranging from factual to fraudulent, with a disproportionate percentage opposed to fluoridation. As fluoridation does not appear to be an important issue for the general public in the U.
Those opposed were much more likely to score higher on outrage factors such as "unclear benefits". Fluoridation by country Despite support by public health organizations and authorities, the practice is controversial as a public health measure; some countries and communities have discontinued it, while others have expanded it.
The following nations previously fluoridated their water, but stopped the practice, with the years when water fluoridation started and stopped in parentheses: Federal Republic of Germany — Sweden —In a large review of the effectiveness of sewage treatment processes in the United Kingdom, UK Water Industry Research (UKWIR), a research body comprising all of the UK water companies, conducted a monitoring study of the concentrations of E1, E2, and EE2 at 14 sewage treatment works.

The water fluoridation controversy arises from political, moral, In the English speaking nations -- the United States, Canada, UK, Australia and New Zealand, all of which practice water fluoridation -- many medical associations and authorities have published position statements and endorsed water fluoridation.
