HONG KONG (Reuters) - China's Yunnan province is investigating possible lead poisoning in its capital city of Kunming, while smelter officials in its top lead producing city, Gejiu, are worried the provincial government may close local smelters with half a million tonnes of annual capacity.
It would be the latest in a series of lead poisoning cases in China, where hundreds of children had been found to have high levels of lead in their blood. China is the world's top producer of lead, a heavy metal that can cause brain damage in children.
