海洋污染
Plastics, excess nutrients, oil, chemicals and untreated sewage reach the sea from rivers, coasts, ships and the air. They harm wildlife, degrade habitats, contaminate seafood and damage tourism and fisheries. This page sets out how marine pollution arises and spreads, how it is measured, and what evidence serves the authorities and industries responsible for reducing it.
Marine pollution: how the risk develops.
Contaminants, plastics and ecosystem harm. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Plastics leak from land
Mismanaged waste reaches rivers and coasts and drifts into the sea, where it breaks into microplastics. Fishing gear lost at sea continues to catch wildlife.
Nutrients fuel dead zones
Fertiliser and sewage runoff deliver nitrogen and phosphorus that drive algal blooms. Their decay consumes oxygen and creates low-oxygen dead zones.
Ships and spills
Oil spills, ballast water, antifouling paints and garbage from ships pollute shipping lanes and ports, with large spills causing acute harm.
Contaminants build up in food webs
Mercury and persistent organic pollutants accumulate in organisms and concentrate up the food chain, affecting wildlife and people who eat seafood.

专家提出的问题。
- Which pollutants reach the sea, from which sources, and by which pathways?
- How do contaminants accumulate in sediments, organisms and food webs?
- What harm do they cause to ecosystems and to human health through seafood?
- How do pollution and climate stressors combine, for example in low-oxygen zones?
- Which interventions upstream or at the coast reduce harm most effectively?
Pathways and harm.
Excess nutrients from fertilisers and sewage fuel algal blooms; when the algae die and decompose, oxygen is consumed, creating hypoxic zones where many species cannot survive. Warming reduces oxygen solubility and strengthens stratification, so 气候变化 and nutrient pollution reinforce each other. Some blooms produce toxins that close shellfish harvesting and affect human health.
Plastics enter the ocean from rivers, coastlines and fishing gear. Large items entangle and are ingested by wildlife; they fragment into microplastics that are now found throughout the ocean. Persistent chemicals and heavy metals accumulate in sediments and biomagnify up food webs, reaching high concentrations in top predators and in seafood. Oil spills cause acute harm to coastal habitats, birds and fisheries, with effects that can persist for years.
Pollution also travels with hazards. Floods and storms flush contaminants, sewage and debris from land into coastal waters at once, so disaster events can produce pollution pulses that affect fisheries and health after the water recedes.
Monitoring and modelling.
Water, sediment and biota
Chemical analysis and biomonitoring measure concentrations; sampling is costly and patchy.
Remote detection
Satellites detect algal blooms, oil slicks and large debris accumulations, with limits under cloud and at small scales.
Transport and fate
Particle-tracking and biogeochemical models simulate where pollutants travel and how they transform.
Limits: microplastic measurement methods are not yet fully harmonised, so results are hard to compare. Source attribution is often uncertain, and long-term health effects of many contaminants remain under study.
