A Greenpeace East Asia (GPEA) investigation has found severe heavy metal pollution and serious health problems at Asia's largest zinc and lead mine and smelting plant in Jinding Town, Lanping County, Yunnan. The findings come against a backdrop of stricter national regulations on the heavy metals industry. In Lanping, one of China's most impoverished counties, however, the Yunnan Provincial Government and Yunnan Jinding Zinc Corporation Ltd., the mine owners, have recklessly compromised the environment and the health of locals in the pursuit of profit.
