The Human Cost of Electronics

Behind every electronic device lies a complex global supply chain that involves many millions of workers and affects countless communities. From the miners who extract cobalt, tantalum, and rare earth elements to the technicians who operate billion-dollar fabrication lines and the laborers who manually dismantle obsolete equipment, the industry employs people in conditions ranging from state-of-the-art clean rooms to hazardous informal recycling yards.

The health impacts of this industry are significant and varied. Semiconductor fabrication relies on hundreds of chemicals, including highly toxic gases such as arsine and phosphine, used as dopant sources, and hydrogen fluoride, used to etch and clean wafers; acute exposures to these substances can cause severe respiratory injury, chemical burns, and, in the case of arsine, the destruction of red blood cells. Assembly work adds repetitive-strain injuries and exposures from soldering fumes and cleaning solvents. Epidemiological research on the sector is still maturing, and findings are not uniform: some cohort studies of semiconductor and electronics workers have reported elevated rates of certain cancers and reproductive effects, while others, including large company-based analyses, have not confirmed a consistent causal link. Historically, the most studied reproductive concern was the association between ethylene-glycol-ether solvents and increased miscarriage rates, which prompted the industry to phase those solvents out of many processes in the 1990s.

Hazards Across the Lifecycle

The nature and severity of health risk vary at each stage of the electronics lifecycle, and so do the controls available to manage it:

• Material extraction: Mining and ore processing expose workers and surrounding communities to dust, heavy metals, and acid mine drainage, with the most severe conditions found in unregulated artisanal operations.
• Wafer fabrication: Clean rooms concentrate toxic and pyrophoric gases, strong acids, and solvents; engineering controls such as gas cabinets, scrubbers, interlocks, and continuous gas-detection systems are the primary line of defense, supported by strict handling protocols.
• Device assembly: High-volume assembly introduces ergonomic strain, solder-fume and flux exposure, and, where leaded solder is still used, the risk of lead exposure.
• Use and service: Repair and refurbishment can release dust and residues, including legacy substances such as lead, mercury, and brominated flame retardants from older equipment.
• End of life: Formal recyclers use enclosed shredding and emission controls, but informal recycling, common in parts of the developing world, relies on open burning and acid baths that release lead, cadmium, mercury, and dioxins into the workers and the surrounding environment.

Because risk is distributed unevenly across this chain, meaningful protection requires controls and oversight tailored to each stage rather than a single uniform standard.

A Justice-Centered Approach

Environmental and occupational health in the electronics industry cannot be separated from questions of justice and equity, because the burdens of production and disposal are not distributed evenly across society. Manufacturing and waste-processing facilities are often sited in areas with less political power to resist them, and discarded electronics frequently move to countries where regulations are weaker and enforcement is limited. The Basel Convention restricts the transboundary movement of hazardous waste, yet substantial volumes still reach informal recycling hubs. Long-running examples such as Guiyu in China and Agbogbloshie in Ghana have been the subject of numerous peer-reviewed studies documenting elevated blood-lead levels in children, heavy-metal contamination of soil and water, and dioxin emissions from the open burning of cables and circuit boards.

Indigenous communities face particular challenges, because many of the materials essential to electronics, and to the wider clean-energy transition, lie on or near their traditional lands; analyses of global mining projects have found that a large share of transition-mineral deposits fall within or adjacent to indigenous territories. Mining can contaminate water supplies, destroy sacred sites, and disrupt traditional livelihoods. Ensuring that indigenous peoples have a genuine voice in decisions affecting their lands, and that they share fairly in the benefits of resource extraction, is both an ethical imperative and, increasingly, a legal expectation grounded in the principle of free, prior, and informed consent.

Standards, Frameworks, and Accountability

A growing body of regulation and voluntary commitment governs health and safety across the electronics value chain. Occupational exposure to fab chemicals is constrained by enforceable limits, such as the permissible exposure limits set by the U.S. Occupational Safety and Health Administration and the recommended limits published by bodies including NIOSH and the ACGIH. Industry guidance, including the World Bank Group and IFC environmental, health, and safety guidelines for semiconductor and electronics manufacturing, sets expectations for emissions control, gas handling, and worker protection. On the social side, the Responsible Business Alliance Code of Conduct addresses labor, health, safety, and ethics across member supply chains, while sourcing rules such as Section 1502 of the U.S. Dodd-Frank Act and the European Union Conflict Minerals Regulation require due diligence on minerals from conflict-affected and high-risk areas, aligned with the OECD Due Diligence Guidance.

Indigenous rights are anchored in the UN Declaration on the Rights of Indigenous Peoples, which articulates the right to free, prior, and informed consent before projects affecting indigenous lands proceed, and in the UN Guiding Principles on Business and Human Rights, which extend corporate responsibility to respect these rights. These instruments do not by themselves guarantee good outcomes, but they create benchmarks against which company conduct, and the conduct of states, can be measured.

Toward Healthier Practices

Addressing the health impacts of electronics requires action at multiple levels. Companies must invest in safer manufacturing processes, substitute hazardous materials where alternatives exist, provide adequate protective equipment and training, and monitor worker health over time through medical surveillance and exposure measurement. Regulators must set and enforce standards that protect both workers and communities, and must control the export of hazardous waste to facilities that cannot manage it safely. Consumers and investors can favor companies that demonstrate a genuine commitment to occupational and community health.

Transparency is essential to progress. Workers and communities need accurate information about the hazards they face and the measures taken to protect them, and independent monitoring and third-party verification help ensure that corporate claims reflect reality rather than aspiration. By bringing these issues into the open and tying them to enforceable standards, the industry can move toward serving human wellbeing rather than undermining it.
