Algal blooms have become an increasingly frequent problem on China's inland lakes because of pollution from industry and farm chemicals.
More than 10,000 workers are battling against time to remove a thick algal bloom that has carpeted the Olympic sailing venue in Qingdao in east China, officials said. A total 5,000 square miles (13,000 square kilometres) is affected, the state news agency Xinhua reported.
A thousand fishing boats have been dredging the area and already 100,000 tonnes of lurid, blue-green algae have been removed. Organisers are also trying to prevent more from spreading into clear waters.
