Fluoride in Water Linked to Lower IQ in Children

Is this the end of water fluoridation?
這是否水氟化的終結？
NEW YORK, Dec. 21, 2010 /PRNewswire-USNewswire/ -- Exposure to fluoride may lower children's intelligence says a study pre-published in Environmental Health Perspectives, a publication of the National Institute of Environmental Health Sciences (online December 17, 2010).
2010年12月21日紐約/新華美通/ - 氟接觸可能會降低兒童的智力，一項研究發表在環境與健康展望說，一份全國環境衛生科學研究所（在線 2010年12月17日）的刊物 。
Fluoride is added to 70% of U.S. public drinking water supplies.
氟被添加到70％的美國公眾飲用水的供應中。
According to Paul Connett, Ph.D., director of the Fluoride Action Network, "This is the 24th study that has found this association, but this study is stronger than the rest because the authors have controlled for key confounding variables and in addition to correlating lowered IQ with levels of fluoride in the water, the authors found a correlation between lowered IQ and fluoride levels in children's blood. This brings us closer to a cause and effect relationship between fluoride exposure and brain damage in children."
根據氟行動網絡董事保羅康尼特博士，“這是第24項研究發現這種關係，但這項研究是較剩餘的強，因為作者們已控制住關鍵的混雜變因，和除卻互相關聯降低的智商相對水含氟的水平，作者亦發現一相關性在低智商和兒童血液中的氟水平之間。這帶我們更接近兒童氟接觸與腦損傷的因果關係。“
"What is also striking is that the levels of the fluoride in the community where the lowered IQs were recorded were lower than the EPA's so-called 'safe' drinking water standard for fluoride of 4 ppm and far too close for comfort to the levels used in artificial fluoridation programs (0.7 – 1.2 ppm)," says Connett.
“亦引人注目的是，在社會內的氟水平，在那降低的智商被發現，是低於環保署所謂的'安全'飲用水水質標準中的氟化物4 ppm，和遠太接近舒適的水平，用於人工加氟項目（0.7 - 1.2 ppm），"康尼特說。
In this study, 512 children aged 8-13 years in two Chinese villages were studied and tested – Wamaio with an average of 2.47 mg/L water fluoride (range 0.57-4.50 mg/L) and Xinhuai averaging 0.36 mg/L (range 0.18-0.76 mg/L).
在這項研究，512名8-13歲兒童在兩條中國村莊被研究和測試 - Wamaio有平均2.47 mg / L的水氟（範圍是 0.57-4.50毫克/ L）和Xinhuai有平均0.36毫克/升（範圍是 0.18 -0.76毫克/升）。
The authors eliminated both lead exposure and iodine deficiency as possible causes for the lowered IQs. They also excluded any children who had a history of brain disease or head injury and none drank brick tea, known to contain high fluoride levels. Neither village is exposed to fluoride pollution from burning coal or other industrial sources.
作者消除鉛接觸與缺碘兩者作為可能降低智商的原因，他們亦排除任何孩子有腦部疾病或頭部受傷的歷史，及沒有人喝磚茶 - 以含高氟水平知名，沒有一條條村有從燃煤或其它工業來源的氟污染。
About 28% of the children in the low-fluoride area scored as bright, normal or higher intelligence compared to only 8% in the "high" fluoride area of Wamaio.
約 28％的兒童在低氟地區取得耀目、正常或更高的智力，相比只得8％在“高”氟區的 Wamaio。
In the high-fluoride city, 15% had scores indicating mental retardation and only 6% in the low-fluoride city.
在高氟城市，15％得分顯示智力遲緩，而在低氟城市只有6％。
The study authors write: "In this study we found a significant dose-response relation between fluoride level in serum and children's IQ."
研究的作者寫道：“在這項研究，我們發現一明顯的劑量反應關係，在血清的氟水平和兒童智商之間。 "
In addition to this study, and the 23 other IQ studies, there have been over 100 animal studies linking fluoride to brain damage (all the IQ and animal brain studies are listed in Appendix 1 in The Case Against Fluoride available online at http://fluoridealert.org/caseagainstfluoride.appendices.html).

One of the earliest animal studies of fluoride's impact on the brain was published in the U.S. This study by Mullenix et. al (1995) led to the firing of the lead author by the Forsyth Dental Center. "This sent a clear message to other researchers in the U.S. that it was not good for their careers to look into the health effects of fluoride – particularly on the brain," says Connett.

Connett adds, "The result is that while the issue of fluoride's impact on IQ is being aggressively pursued around the world, practically no work has been done in the U.S. or other fluoridating countries to repeat their findings. Sadly, health agencies in fluoridated countries seem to be more intent on protecting the fluoridation program than protecting children's brains."

When the National Research Council of the National Academies reviewed this topic in their 507-page report "Fluoride in Drinking Water: A Review of EPA's Standards" published in 2006, only 5 of the 24 IQ studies were available in English. Even so the panel found the link between fluoride exposure and lowered IQ both consistent and "plausible."

According to Tara Blank, Ph.D., the Science and Health Officer for the Fluoride Action Network, "This should be the study that finally ends water fluoridation. Millions of American children are being exposed unnecessarily to this neurotoxin on a daily basis. Who in their right minds would risk lowering their child's intelligence in order to reduce a small amount of tooth decay, for which the evidence is very weak."
