What lead and asbestos teach us about electric vehicles

by Christian Vezilj

For more than a century, society has repeatedly embraced new technologies long before understanding their long‑term consequences. Two of the clearest examples are lead and asbestos, materials once celebrated as miracles of industry. Lead paint was praised for its durability and bright color. Asbestos was hailed as a fireproof wonder material. Both were used everywhere — in homes, schools, factories, and consumer products — and both were considered completely safe. Only decades later did the truth emerge: these substances were silently poisoning millions.

Lead exposure, especially in children, caused irreversible neurological damage. Asbestos fibers, once inhaled, lodge in the lungs and trigger mesothelioma decades later. The tragedy is not simply that these materials were harmful. The tragedy is that the harm was invisible for years, and by the time the evidence became undeniable, the damage had already been done. The same pattern continued with leaded gasoline, which filled the air with toxic particles for generations before regulators finally intervened.

This historical pattern is important because it reveals something about how society evaluates risk. We tend to assume that if something is widely used, it must be safe. We trust convenience, industry, institutions, and experts. We trust that if a danger existed, someone would have discovered it already. But history shows the opposite: the most dangerous exposures are the ones whose effects take decades to appear.

Since COVID, many people have begun to recognize a pattern: the institutions and experts we rely on have not always been transparent. With earlier toxins — lead, asbestos, tobacco, and other industrial chemicals — researchers identified potential dangers long before the public ever heard about them. But those findings were minimized or buried until the evidence became impossible to ignore, often decades later.

The same pattern appears with ultra‑processed foods. Scientific studies raised concerns many years ago, yet only recently has the issue received serious public attention. For decades, these foods were marketed as safe and convenient, while early research pointing to metabolic and neurological risks remained largely overlooked.

Electric vehicles are marketed as clean, modern, and environmentally responsible. And in many ways, they are. But EVs also introduce something unprecedented: constant, close‑range exposure to electromagnetic fields (EMFs) generated by high‑voltage batteries, inverters, and electric motors. These components sit directly beneath or behind the passengers, producing low‑frequency magnetic fields that differ from anything found in gasoline vehicles.

Current research shows that EMF levels inside EVs remain below international safety limits. That is reassuring — but it is also exactly what was said about lead paint, asbestos insulation, and countless other technologies in their early decades. The real question is not whether EVs are dangerous today. The real question is whether long‑term, daily exposure to electromagnetic environments could affect the body’s own electrical systems over time.

The human body is not a mechanical machine. It is an electrical organism. The heart beats through electrical impulses. The brain communicates through electrical signaling. Muscles contract through ion gradients. Every thought, every movement, every heartbeat is an electrical event. So it is reasonable to ask whether decades of exposure to strong, artificial EMFs could influence biological electrical activity in ways we do not yet understand.

If there is an effect, it may not appear immediately. It may not cause sudden illness. It could show up slowly, subtly, and statistically — the same way lead poisoning, asbestos‑related cancers, and tobacco‑related diseases emerged. It may take twenty or thirty years before patterns become visible. And by then, millions of people will have spent thousands of hours sitting inches above high‑voltage systems.

This is why it is fair to ask whether EV‑related EMFs could have long‑term biological effects that we simply cannot detect yet. Electric vehicles may ultimately prove to be completely safe. Or they may reveal subtle long‑term effects on neurological, cardiovascular, or developmental health. We do not know yet — and that uncertainty is precisely the point. The lesson of history is not that every new technology is dangerous. The lesson is that we must not confuse “no evidence of harm” with “proof of safety.” When the human body encounters new forms of exposure, whether chemical, electrical, or nutritional. The question is whether we are willing to learn from the past, or whether we will once again wait for decades of  data before acknowledging risks that were visible from the beginning.
