Bleivergiftung
Lead poisoning was described in a 2001 paper as one of the most common pediatric health problems in China. A 2006 review of existing data suggested that one-third of Chinese children suffer from elevated serum lead levels. Pollution from metal smelters and a fast-growing battery industry has been responsible for most cases of, particularly high lead levels. In 2011, there were riots in the Zhejiang Haijiu Battery Factory from angry parents whose children received permanent neurological damage from lead poisoning. The central government has acknowledged the problem and has taken measures such as suspending battery factory production, but some see the response as inadequate and some local authorities have tried to silence criticisms.
