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 contrast is stark. A modern wafer fab is among the most tightly controlled industrial environments ever built, with continuous gas monitoring, redundant interlocks, and airborne particle counts held orders of magnitude below outdoor air. A few links down the same supply chain, a worker may be burning cable insulation over an open fire to recover copper, with no ventilation, no monitoring, and no medical follow-up.

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, dust capture, and stack emission controls, but informal recycling relies on open burning of cable insulation and acid leaching of circuit boards. These methods expose workers directly to lead, cadmium, and mercury and release dioxins and furans into the surrounding air, soil, and water.

The end-of-life stage carries the heaviest exposure burden relative to the value it creates. The Global E-waste Monitor 2024 reported that the world generated 62 million tonnes of electronic waste in 2022 and that only 22.3 percent of that mass was documented as formally collected and recycled; the remainder was landfilled, stockpiled, or handled outside regulated channels. The World Health Organization has estimated that as many as 12.9 million women and more than 18 million children and adolescents work in or near informal waste processing, where they may encounter heavy metals and combustion byproducts without protective equipment, exposure monitoring, or medical surveillance. Children are of particular concern because their nervous systems are still developing and because lead and other neurotoxicants cause damage at lower doses than in adults.

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

Recognizing Harm: Latency, Evidence, and Compensation

Establishing that a particular illness was caused by a particular job is unusually difficult in electronics, and this difficulty shapes almost everything that follows. Cancers and chronic diseases may not appear until decades after the exposure that caused them, by which time the worker has often changed employers, the process has been redesigned, and the chemicals in question have been replaced. Fabrication also involves simultaneous low-level exposure to hundreds of substances rather than a single dominant agent, so classical occupational epidemiology, which is best suited to isolating one hazard at a time, struggles to attribute effects. Exposure records are frequently incomplete, and detailed process chemistries are often treated as trade secrets, which limits what investigators and treating physicians can learn.

Recordkeeping is therefore a health measure in its own right. In the United States, the Occupational Safety and Health Administration requires employers to preserve employee exposure records for at least thirty years and medical records for the duration of employment plus thirty years, precisely because disease may surface long after the work ends. Programs that pair those records with periodic medical surveillance and biological monitoring, such as blood lead testing for assembly and recycling workers, create the evidence base that later claims depend on.

The long dispute over illnesses among South Korean semiconductor workers illustrates the pattern. It began in 2007, when a young Samsung semiconductor worker died of leukemia and her father refused a private settlement, pressing instead for recognition of the illness as occupational. Advocacy by the group Supporters for the Health and Rights of People in the Semiconductor Industry (SHARPS) sustained the case for more than a decade against the evidentiary obstacles described above. In July 2018 the company and the advocates agreed to accept the binding recommendation of a mediation committee chaired by a retired Supreme Court justice, and in November 2018 Samsung issued a public apology and opened a compensation program covering current and former employees who worked on semiconductor and display lines for a year or more since 1984, with payments of up to 150 million Korean won depending on the illness and length of service. The episode is instructive less for its specific terms than for what it took to reach them: the burden of proof rested for years on the affected families rather than on a vastly better-resourced employer.

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, and amendments adopted in 2022 and operative from January 1, 2025, extended its prior-informed-consent procedure to all electrical and electronic waste, including streams previously handled as non-hazardous. The Ban Amendment, in force since December 2019, additionally prohibits the parties listed in Annex VII, comprising European Union and OECD members plus Liechtenstein, from exporting hazardous waste to parties outside that list. Coverage remains uneven: enforcement depends on national implementation, the United States signed the Convention but never ratified it, and shipments are still routinely declared as working secondhand goods, so substantial volumes continue to 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. A 2022 analysis published in Nature Sustainability geolocated more than five thousand energy-transition mineral projects worldwide and found that 54 percent of them sit on or near the lands of Indigenous peoples. 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 (OSHA), alongside the recommended exposure limits published by the National Institute for Occupational Safety and Health (NIOSH) and the threshold limit values published by the American Conference of Governmental Industrial Hygienists (ACGIH). The distinction matters in practice: most OSHA permissible exposure limits date from 1971 and the agency itself acknowledges that many are outdated, so employers with mature programs commonly work to the more protective NIOSH and ACGIH values rather than to the legal minimum.

Equipment and facility design carry their own conventions. The SEMI S2 guideline sets environmental, health, and safety criteria for semiconductor manufacturing equipment, covering hazards such as chemical containment, fire protection, and energy isolation, and SEMI S8 addresses ergonomic design of that equipment; both are voluntary, but purchasers routinely make conformance a condition of sale. Industry guidance from the World Bank Group and the International Finance Corporation, including the environmental, health, and safety guidelines for semiconductor and other electronics manufacturing, sets parallel expectations for emissions control, gas handling, and worker protection, and is often incorporated by reference into project finance conditions.

On the social side, the Responsible Business Alliance, formerly the Electronic Industry Citizenship Coalition, maintains a Code of Conduct addressing labor, health, safety, environment, and ethics across member supply chains, with conformance assessed through its audit program. Sourcing rules such as Section 1502 of the U.S. Dodd-Frank Act, implemented through the Securities and Exchange Commission's Form SD disclosure, and the European Union Conflict Minerals Regulation, applicable since January 1, 2021, require due diligence on tin, tantalum, tungsten, and gold from conflict-affected and high-risk areas, aligned with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals.

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 International Labour Organization Convention No. 169, which places binding consultation obligations on the states that have ratified it. The UN Guiding Principles on Business and Human Rights extend corporate responsibility to respect these rights and to remediate harms that companies cause or contribute to. These instruments do not by themselves guarantee good outcomes, and consent in practice is often reduced to consultation, 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.

Sound programs follow the hierarchy of controls, which ranks interventions by how reliably they work rather than by how easy they are to implement. Eliminating a hazardous process comes first, followed by substituting a less hazardous material, as the industry did when it moved away from ethylene glycol ethers. Engineering controls come next, including enclosure, local exhaust ventilation, gas cabinets, and interlocks that stop a process before a release reaches a worker. Administrative controls such as procedures, training, and work rotation follow, and personal protective equipment ranks last. Protective equipment sits at the bottom because it protects one person at a time, depends on correct fit and consistent use, and fails silently when it is degraded or worn incorrectly. Treating respirators and gloves as the primary defense is a common and consequential mistake, particularly in refurbishment and recycling operations where capital for engineering controls is scarce.

The same logic applies beyond the fence line. Community protection depends on stack and effluent controls, groundwater monitoring, meaningful siting review, and emergency planning that reaches nearby residents rather than only plant personnel. Where informal recycling is the local livelihood, evidence suggests that formalizing it, by organizing cooperatives, providing safer tools and enclosed dismantling space, and connecting collectors to regulated downstream processing, protects health more effectively than prohibition, which tends to push the activity further out of sight.

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 well-being rather than undermining it.
