What’s on Tap and What You Need to Know About Drinking Water什麼的就挖掘和您需要知道的關於飲用水
By Leigh Erin Connealy, MD由李伊林connealy ，醫學博士 | The National Resources Defense Council (NRDC), an environmental action organization, recently conducted an in-depth study into the quality of drinking water across the United States. |國家資源，國防委員會（ nrdc ） ，一個環境行動組織，最近進行了深入的研究，探討飲用水質量美國各地。 Reviewing the tap water quality data for 19 major US cities, including Los Angeles, they compiled their findings and made them available to the public in June of 2003.檢討自來水質量數據為19個美國主要城市，包括洛杉磯，他們編制了他們的研究結果，使它們向公眾提供在2003年6月。 11 contaminants were labeled to be of “high concern” or “some concern” for the LA area’s water supply. 11污染物標示要“高度關切”或“有些關注”為洛杉磯地區的供水。 Since much of Los Angeles and Orange County由於大部分的洛杉磯和奧蘭治縣 drinking water飲用水 comes from the same two sources, the Colorado River and Northern California, this information should be of note to those living in the Orange County area.來自相同的兩個來源，科羅拉多河和加利福尼亞州北部，這方面的資料應注意對那些居住在奧蘭治縣地區。
Five contaminants fell under the “high concern” category, including Lead, Perchlorate, Radon, Haloacetic Acids (HAAs) and Total Trihalomethanes (TTHMs). 5污染物下跌下， “高度關注” 3個分類，包括鉛，高氯酸鹽，氡氣，鹵乙酸（哈斯）和總三鹵甲烷（ tthms ） 。
Lead 領導
Lead is a heavy metal that generally enters the drinking supplies due to the corrosion of pipes, plumbing or faucets.鉛是一種重金屬，一般來說進入飲用水供應，由於腐蝕的管道，水管或水龍頭。 Often, the lead levels of the很多時候，鉛含量的 water水 at your home are much higher than the levels from the water’s source.在您的家庭遠遠高於水平從水的來源。 This is usually the result of contamination that may be occurring at your home, due to old or corroded pipes.這通常是污染的結果，可能發生在你的家，由於舊的或腐蝕管道。 The national standard (NS) for lead, as determined by國家標準（ NS ）的鉛，所確定的 the EPA環保局 , is 15 ppb. ，是15個ppb 。
Health Effects: Infants, young children and健康的影響：嬰兒，幼兒和 pregnant women孕婦 are particularly susceptible to the adverse effects of lead.特別容易受到不利影響的鉛。 In serious cases, poisoning can cause permanent brain damage and, in less severe cases, can cause children to suffer from decreased intelligence and problems with growth, development and behavior.在嚴重的情況下，中毒可造成永久性腦損傷，在不到嚴重的情況下，可能會導致兒童遭受下跌的情報和問題，與生長，發育和行為。 In adults, lead can increase blood pressure, harm kidney function, adversely affect the nervous system and damage red blood cells.在成人，鉛可以增加血液的壓力，損害腎功能，造成不良影響中樞神經系統和破壞紅血球。
Perchlorate 氯酸鹽
Perchlorate in the water usually comes from rocket fuel spills or leaks at military facilities.高氯酸鹽在水中，通常是來自火箭燃料洩漏或洩漏在軍事設施。 Additionally,此外， perchlorate氯酸鹽 is used in a variety of products and applications, including electronic tubes, vehicle airbags, leather tanning and fireworks.是可用於各種各樣的產品和應用，包括電子管，汽車安全氣囊，皮革鞣制及煙花。 The NS is 4 ppb, however no level has been determined to be safe.的NS是4個ppb ，但NO水平已被確定為安全。
Health Effects: Perchlorate disrupts the健康的影響：高氯酸鹽破壞 thyroid甲狀腺 function and is a suspected功能，是一處被懷疑 carcinogen致癌物質 . 。 Changes in thyroid hormone levels can result in thyroid gland tumors.的變化，甲狀腺激素水平可能會導致甲狀腺腫瘤。 In children, thyroid disruption can adversely affect proper development and in adults it can interfere with metabolism regulation.在兒童，甲狀腺中斷可以產生不利影響的適當發展，並在成人它可以干預與代謝調控。 Disruption of the thyroid in pregnant women may impact the fetus and result in delayed development and decreased learning ability.中斷的甲狀腺在孕婦可能會影響胎兒，並導致延遲的發展和學習能力下降。
Radon 氡氣
Radon is a radioactive gas that results from the natural breakdown of uranium in the ground.氡是一種放射性氣體，結果從天然鈾的分項在地上。 The NS is an average of 300 pCi/L.的NS是一個平均的300個PCI / L的

Haloacetic Acids (HAAs)/Total Trihalomethanes (TTHMs) 鹵乙酸（哈斯） /總三鹵甲烷（ tthms ）
HAAs and TTHMs are volatile organic contaminates often referred to as disinfection by-products or organochlorines and result when哈斯和tthms是揮發性有機化合物的污染往往被稱為消毒副產物或有機氯和結果時， chlorine氯氣 used to disinfect drinking water interacts with organic matter in the water.用來消毒飲用水互動與有機物質在水中。 The那個 EPA環保局 has classified some TTHMs as probable human carcinogens.已分類的一些tthms作為可能的人類致癌物質。 The NS for HAAs is an average of 60 ppb and for TTHMs, an average of 80 ppb.的NS為哈斯是平均60個ppb和tthms ，每年平均有80個ppb 。
Health Effects: Disinfection by-products have been linked to cancers of the bladder, pancreas, colon, rectum, brain, and childhood leukemia.健康的影響：消毒副產物已聯繫到癌症的膀胱，胰腺，結腸，直腸，腦，和兒童白血病。
The following six contaminants fall under the category of “some concern”:以下六個污染物屬於一類“有些關注” ：
