有關電子煙致病物質的調查有全新進展

　　美疾控中心稱電子煙致肺病調查出現新進展

　　The same chemical was found in lung fluid samples from 29 patients in 10 states, the centers for disease control and prevention said today. The finding marks a big step forward in the investigation into the serious and mysterious lung disease caused by e-cigarettes that affects the us.

　　美疾控中心于今日表示，來自10個州的29例患者的肺液樣本中都含有同一化學物質。對于這一影響全美的電子煙致肺?。葒乐赜瞩柢E）調查而言，這一發現標志著巨大進步。

　　The chemical, called vitamin E acetate is now considered a "chemical of concern" by the CDC, which is investigating the outbreak. As of November 5th, 2019, 39 people have died of the injury, and 2,051 cases are being investigated.

　　美疾控中心正對此事展開調查，并認為維生素E醋酸鹽是一種“令人擔憂的化學物質”。截至2019年11月5日，已有39人死于該肺病，目前正在調查的案例有2051起。

　　The agency says that vitamin E acetate is an oily substance found in a ton of typical household items, including foods, supplements, and even skin creams. According to the CDC's website, "Vitamin E acetate usually does not cause harm when ingested as a vitamin supplement or applied to the skin. However, previous research suggests when vitamin E acetate is inhaled, it may interfere with normal lung functioning." 紐約時報中英文網 http://www.244129.buzz

　　該機構表示，維生素E醋酸鹽是一種油性物質，存在于許多典型的家庭用品中，包括食物，補充劑，甚至是護膚品。美疾控中心的官網上寫道，“當作為維生素補充劑攝入或涂在皮膚上時，維生素E醋酸鹽通常不會造成傷害。但先前的研究表明，吸入維生素E醋酸鹽卻可能干擾正常的肺功能運轉。”

　　The oil might be great for skincare, but when heated up, it can act almost like a grease, chemistry professor Michelle Francl told The Washington Post in September. As you might imagine, breathing in vaporized grease could seriously affect the lungs, though researchers are still trying to figure out the exact mechanism that's causing the lung damage.

　　化學教授米歇爾·弗蘭克（Michelle Francl）于9月在接受《華盛頓郵報》的采訪時說道，這種油可能在皮膚護理方面十分有效，但加熱后，它幾乎與油脂無異。正如您所想象的那樣，吸入揮發的油脂會嚴重影響肺部健康，盡管研究人員仍在努力探索導致肺部受損的確切機制。

　　Investigators believe that the substance has been added to e-cigarette products as a thickener, and is particularly attractive to people manufacturing illicit products because it resembles tetrahydrocannabinol (THC) oil. THC is the substance in marijuana that provides a high.

　　調查人員認為，該物質已作為增稠劑添加到電子煙產品中，且由于它與四氫大麻酚（THC）油十分相似，因此極為吸引非法品制造商的注意。四氫大麻酚是大麻中的主要活性成分。

　　Vitamin E acetate was previously linked to the injuries in early September, when some state agencies identified the substance in samples of vaping products that had been used by people who later came down with the disease. But finding it in products wasn't the same as finding it in the patients themselves.

　　維生素E醋酸鹽與9月初的電子煙致傷有關，當時一些州屬機構在后來患上此病的人使用的電子煙產品樣本中識別了這種物質。但在產品中發現這一物質與在患者身上發現這一物質并不屬于同一性質。

　　In this case, researchers looked at fluid taken from the lungs of patients suffering from the injury, and found vitamin E acetate in every single sample. THC was found in 82 percent of the lung fluid samples, and nicotine was found in 62 percent of the samples, suggesting that the vast majority of patients were vaping THC products.

　　在這種情況下，研究員從受傷患者的肺部采集了液體樣本，并在所有樣本中發現了維生素E醋酸鹽，在82%的樣本中發現了四氫大麻酚，在62%的樣本中發現了尼古丁。這表明絕大多數患者吸的都是四氫大麻酚產品。
