Background:Electronic waste (e-waste) is produced in staggering quantities, estimated globally to be 41.8 million tonnes in 2014. Informal e-waste recycling is a source of much-needed income in many low- to middle-income countries. However, its handling and disposal in underdeveloped countries is often unsafe and leads to contaminated environments. Rudimentary and uncontrolled processing methods often result in substantial harmful chemical exposures among vulnerable populations, including women and children. E-waste hazards have not yet received the attention they deserve in research and public health agendas.Objectives:We provide an overview of the scale and health risks. We review international efforts concerned with environmental hazards, especially affecting children, as a preface to presenting next steps in addressing health issues stemming from the global e-waste problem.Discussion:The e-waste problem has been building for decades. Increased observation of adverse health effects from e-waste sites calls for protecting human health and the environment from e-waste contamination. Even if e-waste exposure intervention and prevention efforts are implemented, legacy contamination will remain, necessitating increased awareness of e-waste as a major environmental health threat.Conclusion:Global, national, and local levels efforts must aim to create safe recycling operations that consider broad security issues for people who rely on e-waste processing for survival. Paramount to these efforts is reducing pregnant women and children’s e-waste exposures to mitigate harmful health effects. With human environmental health in mind, novel dismantling methods and remediation technologies and intervention practices are needed to protect communities.Citation:Heacock M, Kelly CB, Asante KA, Birnbaum LS, Bergman AL, Bruné MN, Buka I, Carpenter DO, Chen A, Huo X, Kamel M, Landrigan PJ, Magalini F, Diaz-Barriga F, Neira M, Omar M, Pascale A, Ruchirawat M, Sly L, Sly PD, Van den Berg M, Suk WA. 2016.

AbstractIn many low- and middle-income countries, handling and disposal of discarded electrical or electronic equipment (EEE) is frequently unregulated. e-Waste contains hazardous constituents such as lead, mercury, and chromium, certain chemicals in plastics, and flame retardants. There is increasing concern about health effects related to contamination in air, soil, and water for people working and living at or near informal e-waste processing sites, especially to the most vulnerable populations, pregnant women and children. The observed adverse health effects and increasing number of e-waste sites make protecting human health and the environment from e-waste contamination an expanding challenge. Through international cooperation, awareness can be elevated about the harm that e-waste processing poses to human health. Here we discuss how international researchers, public health practitioners, and policymakers can employ solutions to reduce e-waste exposures.
