Ppt oil spill

  1. 1. • An oil spill is the release of a liquid petroleum hydrocarbon into the environment especially marine areas, due to human activity and is the form of pollution. Oil spills maybe due to release of crude oil, off shore platforms, drilling rigs, and wells as well as spills of refined petroleum products. Cleanup of oil spill is difficult and depends upon many factors. It may take weeks, months or even years.
  2. 2. • Local industries • Human health • Marine ecosystem including animal and plant life • Vegetation & mangroves • Effect on marine life • Damage Beaches, Marshlands and Fragile Marine Ecosystems
  3. 3. • Tourist as fishing, swimming or sailing • Industries that rely on fresh sea water • Devices used to catch fish cannot be used for fear of damaging them in area that have had an oil spill
  4. 4. • Inhalation of vapor, touching oil slicks and consuming contaminated sea food • Causes neurological, acute toxic effects, ocular (eye) and also problems of respiratory system • Nausea, throat infections, nose and eye irritations, etc. along with migraines and headaches.
  5. 5. • Spread of oil slick • Movement (waves)and weather (cold , low energy, little water movement) • Area effected i.e. Estuaries/ foreshore • Proximity to bird breeding colony
  6. 6. • Root areas of plants may be harmful • Living coral is also vulnerable to oil slicks. If the living coral dies, then the reef of coral can be destroyed by wave erosion. • A thick coating of oil on the leaves does almost no damage if it occurs outside the growing season.
  7. 7. • Salt tolerant tress and shrubs and provide habitat for sea birds, crabs, oysters, breeding ground for birds • Their complex root system stabilizes and sediment, preventing soil erosion • They obtain oxygen through lenticels on aerial roots, which may become clogged and stop oxygen supply • There may be long term loss of habitat
  8. 8. • Oil, or hydrocarbons, can affect plants and animals in different ways. • Physical effects on marine birds and mammals is through smothering, where oil coats the outside of their bodies, covering feathers and fur. • Toxic compounds from the spilt oil can be ingested by animals directly, in their prey, as they breath
  9. 9. • Marine mammals are vulnerable to oil spills because of their amphibious habits and their dependence on air. • The rough skin surface, body hair and grooming habits of some species increase the possibility of oil contact, ingestion and associated toxicological effects.
  10. 10. • Absorption of oil by fibrous plants and grasses • Effects on fragile underwater ecosystems • Killing or contaminating many fish and smaller organisms that are essential links in the global food chain.
