Sustainable Development Goals (SDGs) Targets 12.4 and 3.9 aim to reduce deaths and illnesses from hazardous chemicals and to achieve environmentally friendly management of chemical and wastes. Electronic wastes, which contain hazardous chemicals, are rapidly generated in poor countries due to demand for affordable near-end-of-life internet-enabled gadgets that soon wear out and are improperly disposed due to ignorance, throw-away mentality and dearth of waste management infrastructure. This study identified hazardous chemicals contained in significant quantities in e-waste items, described their public health challenges and suggested mitigation measures. Results showed that mercury, polychlorinated biphenyls (PCBs), cadmium, lead and beryllium oxide were hazardous chemicals contained in significant quantities in e-waste items. The study recommended the formulation of appropriate environmental health education technology policy (AEHETP) to guide stakeholders to design education, preventive, therapeutic and decontamination plans for awareness creation and raising to address the toxic effects of e-waste items on users in poor countries.
可持续发展目标（SDGs）的目标12.4和3.9旨在减少有害化学品导致的死亡和疾病，并实现对化学品和废物的环境友好型管理。由于对价格实惠的接近使用寿命末期的联网小工具的需求，电子废物在贫穷国家迅速产生，这些小工具很快就会磨损，并且由于无知、一次性心态和缺乏废物管理基础设施而被不当处置。本研究确定了电子废物中大量含有的有害化学品，描述了它们对公众健康的挑战，并提出了缓解措施。结果表明，汞、多氯联苯（PCBs）、镉、铅和氧化铍是电子废物中大量含有的有害化学品。该研究建议制定适当的环境卫生教育技术政策（AEHETP），以指导利益相关者设计教育、预防、治疗和净化计划，以提高认识并增强人们对电子废物对贫穷国家用户的毒性影响的认识。
