  "term": "Polluted Wetland",
  "field": "Environment",
  "definition": "Although wetlands are capable of absorbing pollutants from the surface water,there is a limit to their capacity to do so. The primary pollutants causing wet-land degradation are sediment, fertilizer, human sewage, animal waste, road salts, pesticides, heavy metals, and selenium. Pollutants can originate from many sources, including: Runoff from urban, agricultural, silvicultural, and mining areas. Air pollution from cars, factories, and power plants. Old landfills and dumps that leak toxic substances. Marinas, where boats increase turbidity and release pollutants.",
