River runs white after chemical leak

A 1-kilometer stretch of the Quxi River in Wenzhou, Zhejiang province, turned white on Monday as emulsion leaked into the tributary from a nearby chemical factory.

The emulsion was not toxic, but environmental experts said the discharge damaged the river.

"The pollutant was identified as natural emulsion, and the factory related (to the case) was shut down temporarily for further investigation," said Dai Dongpeng, a senior officer of the environmental protection bureau in Ouhai district, where the polluted river is located.
