About 20 tonnes of concentrated sulphuric acid leaked from a factory in China that led to billowing acid smoke over the area, officials said.
The incident took place on Monday in Hukou county of east Jiangxi province. There were, however, no casualties and no untoward incident, Xinhua reported citing a government spokesman.
The acid leaked at the Jiujiang Tianci New Material Ltd. in the town's industrial park, he said.
The company implemented emergency measures to collect the acid with help from firefighters and environment protection departments.
Till late Monday, about 18 tonnes of the acid had been transferred to other tanks or collected, but smoke still remained over the area.
