Clues

  • A substance/energy is present in the environment but not causing obvious harm. Many contaminants turn to pollutants but not all of them. All pollutants have been a contaminant before. (13)
  • Also known as diffuse pollution. Difficult to identify the exact origin of the pollution. E.g. run-off of pesticides into a river. - Hard to regulate and monitor. (3, 5, 6)
  • Characterised by the presence of excess physical, chemical and biological substances that changes the qualities of the water. (5, 9)
  • Identifiable points or places that you can easily locate. e.g. sewage plant. - easy to regulate and monitor (5, 6)
  • Linked to water pollution. Both liquid and solid waste can have an impact on soil. (4, 9)
  • Local and global. Gases and solid particles. Presence in the air of abnormal amounts of chemical constituents. (3, 9)
  • The introduction by man into the environment of substances or energy which can cause harm to human health and to living resources and ecological systems. (9)
  • The way the pollutant moves from source, through the environment to the recipient. - Usually reaches humans through consumption of contaminated and polluted water and food and breathing polluted air. (8, 2, 9)
  • Where the pollution comes from/ where it is released from. (6, 2, 3, 9)
