Autism Risk Linked to Distance From Power Plants自閉症的風險聯繫在一起的距離發電廠
By Leslee Dru Browning | How do mercury emissions affect pregnant mothers, the unborn and toddlers?由leslee dru褐變|如何做的汞排放的影響孕婦，胎兒和幼兒？ Do the level of emissions impact autism rates?這樣做的排放水平的影響，自閉症利率？ Does it matter whether a mercury-emitting source is 10 miles away from families versus 20 miles?是否無論汞的排放源是10英里遠離家庭銀兩20英里呢？ Is the risk of autism greater for children who live closer to the pollution source?是風險更大的自閉症兒童誰更接近生活污染源？
A newly published study of Texas school district data and industrial mercury-release data, conducted by researchers at The University of Texas Health Science Center at San Antonio, indeed shows a statistically significant link between pounds of industrial release of新出版的研究德克薩斯州的學區的數據和工業汞釋放的數據，所進行的研究人員在得克薩斯大學健康科學中心在聖安東尼奧，的確顯示了統計學之間的聯繫英鎊的工業釋放 mercury汞 and increased autism rates.並增加自閉症的利率。 It also shows — for the first time in scientific literature — a statistically significant association between它還表明-為第一次在科學文獻-統計學之間的聯繫 autism自閉症 risk and distance from the mercury source.風險和距離的水銀來源。
“This is not a definitive study, but just one more that furthers the association between environmental mercury and autism,” said lead author Raymond F. Palmer, Ph.D., associate professor of family and community medicine at the UT Health Science Center San Antonio. “這不是一個明確的研究，但只是一更認為，進一步加強了協會之間的環境汞和自閉症，說： ”主要作者，何鍾泰樓帕爾默，博士，副教授，家庭和社區中醫藥在對健康科學中心三安東尼奧。 The article is in the journal Health & Place .文章是在雜誌上健康與地點 。
Dr. Palmer, Stephen Blanchard, Ph.D., of Our Lady of the Lake University in San Antonio and Robert Wood of the UT Health Science Center found that community autism prevalence is reduced by 1 percent to 2 percent with each 10 miles of distance from the博士帕爾默，斯蒂芬布蘭查德，博士研究生，我們的聖母湖大學在聖安東尼奧和羅伯特木材的對健康科學中心發現，社區自閉症的流行是減少1 ％至2 ％ ，與每10英里的距離從 pollution污染 source.來源。
“This study was not designed to understand which individuals in the population are at risk due to mercury exposure,” Dr. Palmer said. “這項研究的目的，並非要了解個人在人口處於危險，由於汞暴露， ”博士帕爾默說。 “However, it does suggest generally that there is greater autism risk closer to the polluting source.” “不過，這的確暗示，一般有更大的自閉症的風險接近污染的來源” 。
The study should encourage further investigations designed to determine the multiple routes of mercury exposure.該研究應鼓勵進一步的調查旨在確定的多重路線，汞暴露。 “The effects of persistent, low-dose exposure to “的影響，持續，低劑量接觸 mercury pollution汞污染 , in addition to中，除了 fish consumption魚類消費 , deserve attention,” Dr. Palmer said. ，值得關注的， “博士帕爾默說。 “Ultimately, we will want to know who in the general population is at greatest risk based on genetic susceptibilities such as subtle deficits in the ability to detoxify heavy metals.” “最終，我們會想知道誰在一般人口中是最大的風險基於遺傳易感性等微妙的赤字的能力，解毒重金屬” 。
The new study findings are consistent with a host of other studies that confirm higher amounts of mercury in plants, animals and humans the closer they are to the pollution source.新的研究結果是一致的，與許多其他的研究證實，較高的索賠額中汞的植物，動物和人類密切，他們是污染源。 The price on children may be the highest.價格對兒童可能是最高的。
“We suspect low-dose exposures to various environmental toxicants, including mercury, that occur during critical windows of neural development among genetically susceptible children may increase the risk for developmental disorders such as autism,” the authors wrote. “我們懷疑，低劑量暴露在各種環境毒物，其中包括汞，期間發生的重要的Windows的神經發展之間的基因易感兒童可能會增加風險，為發展障礙，如孤獨症， ”作者寫道。
Study highlights 研究重點
* Mercury-release data examined were from 39 *汞釋放數據研究分別來自39 coal-fired power plants燃煤電廠 and 56 industrial facilities in Texas.和56的工業設施在德克薩斯州。
* Autism rates examined were from 1,040 Texas school districts. *自閉症研究利率分別來自1040年德克薩斯州學區。
* For every 1,000 pounds of mercury released by all industrial sources in Texas into *每1000磅的汞所發表的所有工業來源在德克薩斯州到 the environment環境 in 1998, there was a corresponding 2.6 percent increase in autism rates in the Texas school districts in 2002.在1998年，有一個相應的2.6 ％的增長，自閉症率在得克薩斯州學區在2002年。
* For every 1,000 pounds of mercury released by Texas *每1000磅的汞公佈的得克薩斯州 power plants發電廠 in 1998, there was a corresponding 3.7 percent increase in autism rates in Texas school districts in 2002.在1998年，有一個相應的3.7 ％的增長，自閉症率在得克薩斯州的學區在2002年。

Implications 影響
“We need to be concerned about global “我們需要關心全球 mercury emissions汞排放 since a substantial proportion of mercury releases are spread around the world by long-range air and ocean currents,” Dr. Palmer said.由於相當比例的汞排放是蔓延世界各地的長程空氣和洋流， “博士帕爾默說。 “Steps for controlling and eliminating mercury pollution on a worldwide basis may be advantageous. “步驟，為控制和消除汞污染對全球的基礎上可能有利的。 This entails greener, non-mercury-polluting technologies.” The US Environmental Protection Agency (EPA) estimated environmental mercury releases at 158 million tons annually nationwide in the late 1990s, the time period studied by the Texas team.這就需要綠化，無汞污染技術“ ，美國環境保護署（ EPA ）估計，環境汞的排放在一萬五千八點零零零萬噸每年在全國范圍內，在20世紀90年代末，時間內，研究了得克薩斯州隊。 Most exposures were said to come from coal-fired utility plants (33 percent of exposures), municipal/medical waste incinerators (29 percent) and commercial/industrial boilers (18 percent).大部分的風險，據說是來自燃煤公用事業植物（ 33 ％的風險） ，市政/醫療廢物焚化爐（ 29 ％ ）和商業/工業鍋爐（ 18 ％ ） 。 Cement plants also release mercury.水泥廠也釋放汞。
With the enactment of clean air legislation and other measures, mercury deposition into the environment is decreasing slightly.與通過清潔空氣的立法和其他措施，汞沉積到環境是略有下降。
Limitations 限制
Dr. Palmer and his colleagues pointed out the study did not reflect the true community prevalence rates of autism because children younger than school age are not counted in the Texas Education Agency data system.博士帕爾默和他的同事們指出，這項研究並沒有反映真實社會的患病率自閉症的兒童，因為年輕，比學齡不計入在得克薩斯州教育機構的數據系統。 The 1:500 autism rates in the study are lower than the 1:150 autism rates in recent reports of the US Centers for Disease Control and Prevention.該1:500自閉症率在研究低於1:150自閉症的利率在最近的報告，美國疾病控制中心和預防工作。
Furthermore, the authors note that distance was not calculated from individual homes to the pollution source but from central points in school districts that varied widely in area.此外，作者指出，距離沒有計算從個別安老院污染源，但由中央點在學校地區的差別很大，在面積。
Data sources 數據來源
Data for environmentally released mercury were from the United States Environmental Protection Agency Toxics Release Inventory.數據環境釋放汞分別來自美國環境保護局的有毒物質釋放庫存。 Data for releases by coal-fired power plants came from the same inventory and from the Texas Commission for Environmental Quality.數據發布由燃煤發電廠來自同一清單，並從得克薩斯州委員會環境質量。 Data for school district autism came from the Texas Education Agency.數據為學區自閉症來自得克薩斯州的教育機構。

There was an article in “Wired” a while back which noted the concentration of autism in Silicon Valley, and Rochester Minnesota, both areas where “Nerd Engineers” make their home and their living (not to mention all of the nurses capable of passing chemistry working at the Mayo Clinic).有一篇文章在“有線”一回，而其中指出濃度的自閉症，在矽谷，和羅徹斯特明尼蘇達州，這兩個地區的“老古板工程師” ，使他們的家和他們的生活（更不用提，所有的護士能夠通過化學工作在Mayo Clinic的） 。 I have read many anecdotes about the high rates of Asperger’s among engineers, (I estimate about 1/4 of engineers), and everywhere I have worked, my peer engineers have had autistic children.我已看過許多軼事約率高的輕的，其中工程師， （我估計約1 / 4工程師） ，和我到處都工作了，我同儕的工程師已自閉症兒童。 so it would seem that near every power plant you would have a disproportionate population of engineers, and thus a cluster of autism cases, so why would you blame autism on mercury, when there is actually much less mercury in the environment than in years past?因此，似乎附近的每一個火電廠，你將有一個不成比例的人口的工程師，因此一組自閉症的案件，為什麼你會責怪自閉症對汞，當有其實是少得多汞在環境中比在過去幾年裡呢？ We used to have coal furnaces in our basements, my son’s turn of the previous century home still has coal dust on all of the floor joists, and we didn’t have an epidemic of autism then.我們使用的有煤火爐，在我們的地下室，我兒子的之交，上個世紀首頁仍然有煤塵對所有的樓托梁，和我們沒有流行的自閉症。 If you think there has been an uptick in autism, ask yourself- when was the last time your community had to increase the number of beds in the facilities which are caretakers for the autistic and the retarded?如果你覺得有一種福特公司儘管在自閉症，問問自己-當是最後一次您的社會，以增加病床數目，在該設施是管理員為自閉症及智障？
