Chemicals in our water could be dangerous
Municipal water in South Africa is well treated and certainly safe from the real nasties like cholera, typhoid and other frightening water-born illnesses, says Tony Marchesini, Managing Director of H2O International. But once the water reaches your home, you really should be removing the chemicals like fluoride, especially if you already using a fluoride toothpaste. You have no idea how many chemicals have leached into your water since it was treated and at what levels they are present.
With regard to fluoride levels, a quote from Rand Waters explanation for their stance against fluoridation makes for salient reading:
As water is a scarce commodity in South Africa, it is recycled, and this should be considered in the overall water use strategy. Fluoridation of Rand Waters supply at a rate of 0,5 mg F-/l will introduce 365 tons of fluoride per annum into the environment. If 0,5 mg F-/l is added to our water supply this would theoretically imply (during periods of drought or the dry season) that the effluent concentrations will also increase by 0,5 mg F-/l as fluorides are not appreciably removed through the wastewater treatment process.
Low levels of fluoride are toxic to immune system cells
When the legislation was enacted, Bettina Genthe, a water analyst with Environmentek, a business unit of the CSIR, told Parliaments water affairs portfolio committee, Weve got a number of factors which affect the health impact of fluoride in this country one of these is that malnutrition makes fluoride more toxic than it is to people who are well nourished There is no doubt that fluoride is good for teeth, and it protects against decay but water fluoridation might not be the best way of achieving this protection.
After the briefing, Genthe said that in laboratory studies It appears to be that fluoride can be toxic at very low concentrations to imm...
