据《京华时报》报道，卫生部周六发布的一份报告显示，全国10%的游泳池尿素和余氯含量超标。
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.

卫生部通报了今年游泳场所水质卫生监督抽检结果，尿素合格率为90.8%，而余氯合格率为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质不能被有效循环净化。
The high urea content is due to the ineffective cleaning and recycling of water.

个别游泳场所未按要求安装或未正常运行游泳池水循环净水和消毒设备，而是采取每日不定时人工抛撒式投消毒药的方法，无法确保游泳池按时彻底清洁。
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.
