The local environment protection department says the battery factory is too close to the residential area. That is why the region's children have been exposed to lead. In addition, the factory enlarged its production capacity without receiving the approval to do so.

An official from environmental Protection Bureau, said, "The factory was originally approved to produce 500 thousand sets. But now it annually produces 1.3 million sets, two times what is was approved for."

The environmental protection department shut down the plant and fined the factory 50 thousands yuan. The local government is requesting the plant pay 500 thousands yuan in advance to the region's hospital as treatment fees for the 6 hospitalized children.
