Piles of computer waste lie everywhere in Guiyu. Every year Guiyu takes in more than a million tons of computer waste, imported primarily from the United States, Japan and South Korea. About 40,000 local farmers and 100,000 migrant workers make their living from the e-waste, which contains toxic ingredients such as lead, beryllium and mercury. The workers risk catching respiratory and skin deseases, eye infections and even cancer.
