Other informal e-waste recycling sites

Guiyu is likely one of the oldest and largest informal e-waste recycling sites in the world, however, there are many sites worldwide, including India, Ghana, Nigeria, and the Philippines. Most research involving informal e-waste recycling has been done in Guiyu, but there are a handful of studies that describe exposure levels in e-waste workers, the community, and the environment. Bangalore, located in southern India, is often referred as the "Silicon Valley of India" and has a growing informal e-waste recycling sector. Hair samples were collected from workers at an e-waste recycling facility and a e-waste recycling slum community in Bangalore. Levels of V, Cr, Mn, Mo, Sn, Tl, and Pb were significantly higher in the workers at the e-waste recycling facility compared to the e-waste workers in the slum community. However, Co, Ag, Cd, and Hg levels were significantly higher in the slum community workers compared to the facility workers. A study in Ghana found higher levels of urinary PAH-metabolites in e-waste workers compared to unexposed controls. They also found a greater frequency of complaints of cough, chest pain, and vertigo from those exposed to emissions from the e-waste recycling processes.
