The most alarming report is that from researchers at Peking University Health Sciences Center in Beijing, which shows 10 years of data on lead poisoning. Its conclusion: About 34% of children in China have blood levels that exceed the WHO limit of 100 micrograms per 1 litre of blood. A whole generation of children may be compromised. To avoid being noticed factories that have toxic byproducts or emissions are being setup in the countryside. Lead products are added to herbal products that are sold by weight to make them weigh more. It is regularly added to plastics and vinyl to make it temperature resistant. Once in the human bloodstream lead mimics other substances like calcium and zinc and iron and binds to sites in the brain intended for calcium disrupting brain cells leading to ireversible brain impairment. See the article in August 2, 2007 NYT, about the recall of 1 million Mattel toys, Elmos and Big Birds, for lead detected in them. Note that Mattel's monitoring system did not catch this, it was caught by a retailer.
