游泳池里的水是否干净?

2010-06-07来源:和谐英语

Everybody loves the swimming pool. But how clean is the water in the average backyard or public pool? If you trust chlorine to take care of germs, you're in for a surprise. 

每个人都喜欢游泳。但,普通的自家后院的泳池和公共泳池中的水干净吗?如果你信任氯的杀毒功效,本文会让你大吃一惊。

Chlorine and other disinfectants do indeed help to clean the water, but some germs can survive in even the best-kept pool. For example, cryptosporidium may live in pool water for several days. Crypto causes a diarrheal illness and may rinse off the bodies of infected people or diapered children into the pool. If you swallow infected pool water, you may become sick.

氯和其他一些杀菌剂的确可以帮助净水,但就算在卫生条件最好的泳池里,一些细菌仍然能够存活。比如,隐孢子虫能够引起人的腹泻,并可以在泳池中存活几天。受感染者或使用尿布的儿童都能将隐孢子虫带到泳池内。如果你呛了口有隐孢子虫滋生的池水,你可能会生病。

Other germs may live for a few minutes or a few hours in a chlorinated pool: Giardia, Shigella, and E. Coli may cause diarrheal illnesses. Pseudomonas Aeruginosa may cause an ear infection called swimmer's ear and also a skin infection called "hot tub rash," that is usually associated with very warm pools and spas.

在用氯消毒过的泳池内,有些细菌能够存活几分钟或是几小时:鞭毛虫,志贺氏杆菌,大肠杆菌。它们都能引起腹泻。通常,在水温较高的泳池和温泉中,绿脓杆菌能感染人的耳部和皮肤,导致游泳性耳炎和毛囊炎的发生。

While keeping the correct chlorine and ph levels will minimize water-borne illness, prevention is also a good idea. Keep diapered children in the water for only brief periods and keep sick people out of the water altogether. And, don't ever swallow pool water.

控制好水中的氯的含量和PH值会减少水传播疾病的可能,除此之外,做好防护工作也是一条可行之路。不让还戴尿布的孩子长时间在水中逗留,生病的人都不要下水。还有,不要呛到池水。
