Guiyu (Chinese: 贵屿; pinyin: Guìyǔ) is a town created from an agglomerate of four adjoined villages totalling 150,000 people in the Chaoyang district of Guangdong province in China.

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.

[6] The same study revealed that sediment from the nearby Lianjiang River was found to be contaminated by polychlorinated biphenyls at a level three times greater than the amount prescribed in the guideline.

Air and water quality subsequently improved in the town, though many were still left contaminated from the remnants of e-waste processing and have not been cleaned up.

[7] In 2005 the Italian band Planet Funk shot and published the music video for their song "Stop Me" in which Guiyu and its e-waste environment are portrayed.
