海外网9月13日电 据日本NHK电视台12日晚消息，今年5月及7月，位于日本神奈川县横须贺市的美国海军基地排水处理场接连检测出对人体有害的有机氟化物，其含量皆超过日本标准数值。    (ECNS) -- More than 2,000 humanoid robots from 16 countries will compete at the second World Humanoid Robot Games in Beijing from Aug. 22 to 26, a sports official said Thursday.     A total of 666 teams and 2,056 robots have registered, said Yu Qingfeng, director of the Beijing Sports Bureau and executive deputy director of the Games’ organizing committee.        The Games will feature 1,301 contests across 51 events at the National Speed Skating Oval, also known as the “Ice Ribbon.”    Highlights include robot soccer, with participants now able to dribble while running, take powerful shots and dive to make saves.    Robots will also compete in combat, weightlifting and dance, while other events will test practical skills such as emergency response, hotel services and fine movements like picking up beans and tightening screws.    Dance events have attracted 108 teams, up from 29 last year, with robots set to compete in street dance, ballroom dance and cheerleading.             Competition standards have been tightened, with the 100-meter race time limit cut from three minutes to one, and most events required to be completed autonomously.     (By Helen Mo, intern Yang Hongran)                    。横须贺市政府表示，5月，驻日美军横须贺基地的排水处理设施被曝检测出PFOS（全氟辛烷磺酰基化合物）、PFOA（全氟辛酸铵）。事发两个月后，美军于7月再次进行检测，发现基地内两处排水处理厂入口附近仍有相关有害物质残留，含量约为标准值的2倍，原因不明。《神奈川新闻》分析认为，这些污染物很可能已通过排水管流入海洋。横须贺市市长上地克明认为美军基地“常态化排放”有害物质，已提出抗议。美军回复日本防卫省，正对此进行调查，并将采取措施，如设置活性炭来吸附有毒物质，并定期处理污泥。（海外网/王珊宁）
