in the slum community. However, Co, Ag, Cd, and Hg levels were significantly higher in the slum community workers compared to the facility workers. Even in formal e-recycling industry, workers can be exposed to excessive pollutants. Studies in the formal e-recycling facilities in France and Sweden found workers' overexposure (compared to recommended occupational guidelines) to lead, cadmium, mercury and some other metals, as well as BFRs, PCBs, dioxin and furans. Workers in formal industry are also exposed to more brominated flame-retardants than reference groups. Hazard controls For occupational health and safety of e-waste recycling workers, both employers and workers should take actions. Suggestions for the e-waste facility employers and workers given by California Department of Public Health are illustrated in the graphic.
