據(jù)《京華時報》報道，衛(wèi)生部周六發(fā)布的一份報告顯示，全國10%的游泳池尿素和余氯含量超標。
According to a report released Saturday by the Ministry of Health (MOH), roughly 10 percent of swimming pools have unsafe levels of urea and residual chlorine, the Beijing Times reported.

衛(wèi)生部通報了今年游泳場所水質(zhì)衛(wèi)生監(jiān)督抽檢結(jié)果，尿素合格率為90.8%，而余氯合格率為83.7%。
The MOH report revealed that only 90.8 percent swimming pools had an acceptable urea index with 83.7 percent having an acceptable residual chlorine index.

游泳池水尿素含量偏高的主要原因是水質(zhì)不能被有效循環(huán)凈化。
The high urea content is due to the ineffective cleaning and recycling of water.

個別游泳場所未按要求安裝或未正常運行游泳池水循環(huán)凈水和消毒設(shè)備，而是采取每日不定時人工拋撒式投消毒藥的方法，無法確保游泳池按時徹底清潔。
Some swimming pools do not install or operate the recycling cleaning and sterilization facility, and depend instead on randomly cleaning the pool with disinfectants, which does not guarantee that cleaning is thorough or regular.
