China's official Xinhua news agency reported on Wednesday that workers had dredged around 100,000 kilograms of dead fish from a 40-km (25-mile) stretch of the Fuhe river, near the heavily populated city of Wuhan in Hubei province in central China following a toxic spill.
The provincial environmental protection agency had identified the Hubei Shuanghuan Science and Technology Stock Co Ltd as the company responsible for Monday's spill, with ammonia levels found to be beyond acceptable levels, Xinhua said.
Hubei Shuanghuan Science and Technology, a manufacturer of inorganic chemicals, apologised on Friday and said it began a week-long production halt on Wednesday and blamed the spill on a sewage release "that exceeded standard levels".
