Rice paddies in Guiyu, China's computer waste centre. E-waste recycling is poisoning the air, land and water on which local people depend. Via polluted irrigation water that is used in the rice fields next to the river, the heavy metals end up in the human food chain..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 as lead, beryllium and mercury. The workers risk to be rewarded with respiratory and skin deseases, eye infections and even cancer.
