title: Chemical Pollution -Novel Substances-

  • Humans engineered new chemical compounds that did not exist before and that no ecosystem has adapted to
    • These can be toxic substances that are not easily dissipated in the environment
    • They are often transported in long distances affecting a variety of ecosystems
  • High risk of irreversability

Examples of of Novel substances

  • Radioactive wastes and heavy metals
    • Mercury (exposes ecosystems to high levels of pollution)
      • Problems of mercury in fish and then humans
  • Chlorofluorocarbons
  • DDT (pesticide)
    • Persists for years in soils and sediments
    • Carried throughout the food chains
