Electronic waste in Guiyu
Guiyu, in Guangdong Province, China, is an agglomerate of four adjoined villages widely perceived as the largest electronic waste (e-waste) site in the world. In 2005 there were 60,000 e-waste workers in Guiyu who processed the more than 100 truckloads that were transported to the 52 square kilometre area every day. The constant movement into and processing of e-wastes in the area leading to the harmful and toxic environment and living conditions, coupled with inadequate facilities, have led to the Guiyu town being nicknamed the "electronic graveyard of the world"''.
==Health impacts==
Many of the primitive recycling operations in Guiyu are toxic and dangerous to workers' health with 80% of children suffering from lead poisoning. Above-average miscarriage rates are also reported in the region. Workers use their bare hands to crack open electronics to strip away any parts that can be reused—including chips and valuable metals, such as gold, silver, etc. Workers also "cook" circuit boards to remove chips and solders, burn wires and other plastics to liberate metals such as copper; use highly corrosive and dangerous acid baths along the riverbanks to extract gold from the microchips; and sweep printer toner out of cartridges. Children are exposed to the dioxin-laden ash as the smoke billows around Guiyu, and finally settles on the area. The soil has been saturated with lead, chromium, tin, and other heavy metals. Discarded electronics lie in pools of toxins that leach into the groundwater, making the water undrinkable to the extent that water must be trucked in from elsewhere. Lead levels in the river sediment are double European safety levels, according to the Basel Action Network.〔 Lead in the blood of Guiyu's children is 54% higher on average than that of children in the nearby town of Chendian.〔http://ehp.niehs.nih.gov/realfiles/members/2007/9697/9697.html 〕 Piles of ash and plastic waste sit on the ground beside rice paddies and dikes holding in the Lianjiang river.
A recent study of the area evaluated the extent of heavy metal contamination from the site. Using dust samples, scientists analysed mean heavy metal concentrations in a Guiyu workshop and found that lead and copper were 371 and 115 times higher, respectively, compared to areas located 30 kilometres away. The same study revealed that sediment from the nearby Lianjiang River was found to be contaminated by polychlorinated byphenyls at a level three times greater than the guideline amount.
