Chinese state media say a battery plant has been closed after more than 120 children living nearby were found to have lead poisoning.
Officials in the city of Longyan in the south-east province of Fujian have launched an inquiry into the poisoning, Xinhua news agency says.
Authorities say they will pay medical costs and test all children aged under 14 who live near the plant.
China has reported a series of cases of children with lead poisoning this year.
Last month, hundreds of children living near smelting plants in Shaanxi and Hunan were found to have excessive amounts of lead in their blood. read more
