Ocean Pollution × Coastal Cancer

Coastal populations breathe sea-spray aerosols, drink from watersheds that empty into polluted bays, and eat seafood that bioaccumulates POPs. This page overlays the ten most documented US marine pollution hotspots with cancer signals in the states that border them.

Coastal state cancer overlay

Age-adjusted all-site cancer incidence (per 100,000), with the specific elevations researchers tie to nearby marine pollution. National all-site average ≈ 442.3.

How pollutants reach people

  • Seafood bioaccumulation — mercury, PCBs, PFAS, microplastics climb the food chain.
  • Sea-spray aerosols — PFAS, brevetoxin, and microplastic fibers become inhalable within 1–3 km of shore.
  • Drinking water intakes — coastal aquifers and river intakes pull from the same polluted watersheds.
  • Recreational exposure — swimming, surfing, and shellfish harvesting in advisory zones.

The strongest signals

  • PFAS → kidney & testicular cancer (IARC Group 1, 2023). Hotspots: Cape Fear, Cape Cod, Pease AFB.
  • Benzene → leukemia. Hotspots: Houston Ship Channel, Cancer Alley.
  • PCBs → liver, melanoma, NHL. Hotspots: Hudson, Puget Sound, Chesapeake.
  • Microcystin → liver (IARC 2B). Hotspots: Chesapeake, Lake Erie, FL inland.
  • Methylmercury → suspected co-carcinogen. Hotspots: SF Bay, Alaska subsistence fisheries.
Caveats

Coastal state cancer incidence reflects many overlapping drivers — age structure, smoking, screening density, access to care, and occupational exposures — not just ocean pollution. The overlay is useful for hypothesis generation, not attribution. Sources: CDC USCS, EPA NATA & TRI, NOAA HAB Reports, IARC Monographs, NIEHS, USGS National Water Quality Assessment.
