Pools Turn Green at Rio Olympics
里约水池变绿
The outdoor diving pool at the Rio Olympics turned green this week, leaving many wondering if the water was safe for athletes to swim in. Though the cause of the discolouration is currently unknown, officials say the water has been tested thoroughly and there is no risks to athletes. There are several theories about why the pool would turn green. Some pool experts believe it is a build up of algae while others say it’s due to a lack of chemicals. Shortly after organizers assured athletes that the diving well would be blue again soon, the adjacent water polo pool turned green as well.
本周，里约户外跳水池突然变绿，运动员安全存疑。尽管变色原因还不得而知，但官方称已对水池进行全面检测，它对运动员不构成危害。关于水池变绿有多个版本。许多专家称是水藻繁殖，还有人称是是缺少某种化学物质。就在主办方承诺回归“本色”后不久，旁边的水球池也被染成了一抹绿色。
