Land Quality & Pollution

  1. 1. LAND QUALITY & POLLUTION<br />
  2. 2. Land with pollutants at above-background concentrations causing, or with the potential to cause, adverse impacts to human health, the environment or any environmental value.<br />‘Pollutants&apos; refers to chemicals such as heavy metals, pesticides, herbicides, oils, hydrocarbons and other toxic chemicals. <br />
  3. 3. The toxicity and persistence of pollutants in soils, as well as their direct uptake by people, plants and animals, is the major concern with land contamination. <br />
  4. 4. Contaminated sites are usually identified after the polluting activity or land use has ended and the land is being redeveloped for another use.<br /> Some contaminated sites are identified once groundwater pollutant plumes are detected in inland waters or bore water. <br />
  5. 5. Pollutants can bind to soil particles and be taken up by vegetation, thereby entering the foodchain.<br />
  6. 6. Pollutants that do not bind to soil can get washed down to the water table, or blown away by wind to a new location.<br />
  7. 7. Abidjan, <br />Ivory Coast,<br />Africa<br />
  8. 8. The ship Probo Koala dumped the waste after deeming European disposal methods too expensive. <br />
  9. 9. The city borders a large lagoon, now poisoned by the toxic oil sludge. <br />
  10. 10. When it rains, the water flows through the streets. With the water comes a toxic soup of industrial poison -- a dark, glistening mess reeking of sulphur and rotten eggs. The caustic fumes it releases cause vomiting, nosebleeds, headache and rashes.<br />Official local autopsy reports on 12 alleged victims appeared to show fatal levels of the poisonous gas hydrogen sulphide, one of the waste&apos;s lethal by-products.<br />http://www.guardian.co.uk/world/audio/2009/sep/17/trafigura-oil-toxic-dumping<br />
  11. 11. Waste removal experts clear hazardous material from a site in Abidjan, Ivory Coast in November 2006. <br />http://www.guardian.co.uk/world/2009/sep/16/trafigura-african-pollution-disaster<br />
  12. 12. Chernobyl, Ukraine<br />
