Human activities add mercury to the environment, where it can enter aquatic food webs and become methylmercury in fish and shellfish. People are exposed in different ways: eating contaminated seafood is a common route for methylmercury, while breathing vapor from spilled elemental mercury is a separate hazard. The risks depend on the mercury’s chemical form, amount, route and duration of exposure, and who is exposed.
What is mercury pollution?
Mercury is a naturally occurring element in the Earth’s crust, but natural occurrence does not account for every source of mercury in the environment. Human releases come from activities including coal-fired power generation, residential coal burning, industrial processes, waste incineration and mining. Once released, mercury can circulate through air, water and soil. The World Health Organization (WHO) identifies mercury as one of the top ten chemicals of major public-health concern; that is a public-health characterization, not a numerical ranking.
Mercury pollution matters to human health because some forms persist in the environment and move through food webs, while other forms can pose a direct hazard when people inhale vapor or encounter compounds at high exposure levels.
How does mercury get into fish?
Mercury can settle into aquatic environments. Microorganisms in water and sediments can transform it into methylmercury, an organic form that aquatic organisms take up. It accumulates in organisms and becomes more concentrated through the food web. Larger fish higher on the food chain, especially long-lived predatory species, tend to have higher methylmercury levels.

Eating fish and shellfish is a common way people are exposed to methylmercury. In the United States, the Environmental Protection Agency (EPA) describes it as the most common route of mercury exposure. That statement is specific to the United States; exposure patterns and local advice can vary elsewhere.
How are mercury’s forms and exposure routes different?
“Mercury” does not describe one uniform exposure. The chemical form affects how it enters the body and the kinds of harm it can cause.

| Form | Typical exposure route or context | Health concerns described by authorities |
|---|---|---|
| Methylmercury | Eating contaminated fish and shellfish | Can harm the nervous system; exposure during pregnancy can affect a child’s developing brain. |
| Elemental (metallic) mercury | Breathing vapor, including after a mercury-containing product breaks or spills | Vapor can cause neurological effects; high exposures may also cause kidney effects, respiratory failure and death. |
| Inorganic mercury compounds | Exposure depends on the particular compound and circumstances | High exposure can damage the gastrointestinal tract, nervous system and kidneys. |
WHO’s 24 October 2024 mercury fact sheet says, “Methylmercury is very different to ethylmercury.” These terms should not be conflated: that distinction does not change how environmental methylmercury forms and accumulates in aquatic food webs.
How can mercury exposure affect health?
The effects depend on the mercury form, dose, route and duration of exposure, as well as the exposed person’s age and health. EPA describes neurological harm as a concern for methylmercury. During prenatal development, exposure can affect a child’s cognitive thinking, memory, attention, language, fine motor skills and visual-spatial skills. Early childhood is also a particularly vulnerable stage for nervous-system development.

Effects associated with elemental mercury vapor
Inhaled metallic mercury vapor can cause tremors, emotional changes, insomnia, headaches, and sensory or neuromuscular changes. At higher exposure levels, kidney effects, respiratory failure and death are possible.
Effects associated with inorganic mercury
High exposure to inorganic mercury compounds can harm the gastrointestinal tract, nervous system and kidneys. These effects are distinct from methylmercury’s food-web pathway and from inhaling elemental mercury vapor.

How serious is methylmercury exposure from fish?
WHO’s 2024 fact sheet reports that “among selected subsistence fishing populations, between 1.5/1000 and 17/1000 children showed cognitive impacts caused by the consumption of fish containing mercury.” The estimate applies to selected subsistence fishing populations; it is not a global prevalence estimate and should not be generalized to all children or fish consumers.
Fish also provides nutritional benefits. A 25 September 2024 background document from the Food and Agriculture Organization of the United Nations and WHO reviews those benefits alongside methylmercury toxicity and contaminant occurrence in fishery and aquaculture products. The practical implication is not that all fish are unsafe: EPA encourages people to choose fish low in methylmercury. Which fish advice applies depends on species and location, so consult local advisories for the waters and fish you use.

What should you do about a possible exposure?
- For fish consumption: Check relevant local or national advisories for the species and waters involved. Advice can differ by fish and location; avoid assuming one universal list applies everywhere.
- For a broken product or spill: Elemental mercury vapor is an inhalation hazard. If you are concerned about a possible exposure, contact a physician or other health-care provider rather than trying to diagnose the risk from symptoms alone.
- For urgent guidance in the United States: EPA’s health-effects page lists Poison Control at 1-800-222-1222. This number is for the United States.
