Beijing: Workers began cleaning up a chemical spill in northeastern China on Thursday after more than 3,000 containers of chemicals were washed into a river by the worst floods to hit the country in more than decade.
The buckets, containing a flammable chemical used to make rubber and adhesives, tumbled into the Songhua River near Jilin city in Jilin province after a flood swept through a local factory, the official Xinhua News Agency reported. Only about 400 buckets had been recovered as of Thursday morning. No further details were immediately available.
The Songhua has had environmental problems before. In 2005, carcinogenic chemicals, including benzene, spilled into the river, forcing the northeastern city of Harbin to sever water supplies to 3.8 million people for five days.
Floods this year have killed at least 928 people, left 477 missing and caused tens of billions of dollars in damage, the State Flood Control and Drought Prevention office reported. More heavy rains were expected for the southeast, southwest and northeast parts of the country through Friday.
That included about 30,000 residents trapped and left without power in their homes in Jilin after torrential rains drenched the town of Kouqian, Xinhua reported.
Flooding has hit areas all over China. Thousands of workers sandbagged riverbanks and checked reservoirs in preparation for potential floods expected to flow from the swollen Yangtze and Han rivers, an official with the Yangtze Water Resources Commission. He gave only his surname, Zhang, as is common with Chinese officials.
"Right now, the Han river in Hubei province is on the verge of breaching warning levels," Zhang said.
The Han is expected to rise this week to its highest level in two decades, Xinhua reported. The flood threat was greater than usual because the Yangtze, into which the Han flows, was also reaching peak levels, it said.
Although China experiences heavy rains every summer, flooding this year is the worst in more than a decade because the flood-prone Yangtze River Basin has seen 15 percent more rain than in an average year, Duan Yihong, director of the National Meteorological Centre, said in a transcript of an interview posted on the Xinhua website.
"Rains should begin to slow down in August, but it is hard to predict now what exactly will happen," said Duan. "We have to be vigilant and closely monitor the weather ... do a better job of forecasting."
Floods have also put China`s massive Three Gorges Dam to the test. On Wednesday morning, the dam`s water flow reached 1.96 million cubic feet (56,000 cubic meters) per second, the biggest peak flow this year, with the water level reaching 518 feet (158 meters), Xinhua said, about 10 percent less than the dam`s maximum capacity.
Chinese officials have for years boasted the dam, the world`s largest hydroelectric project, would end centuries of devastating floods along the Yangtze.
Around China, a total of 875,000 homes have been destroyed, 9.61 million people evacuated, and 22 million acres (8.76 million hectares) of crops ruined in this year`s flooding, according to the state flood control office.
China`s worst flooding in recent years occurred in 1998, when 4,150 people were killed, most along the Yangtze.
