  1. Oil Pollution

  2. What is an Oil Spill? • Release of a liquid petroleum hydrocarbon into the environment • Marine spills • Oil is released into ocean or coastal waters • crude oil, refined petroleum (gasoline or diesel fuel)

  3. Main Cause of Oil Spills • Equipment breaking down • Tankers, barges, pipelines, refiners, and oil storage facilities • Natural disasters- • Hurricanes, seep up from ocean floor • Man mad reasons- • Car oil, routine maintenance

  4. Major Oil Spills • Pose a danger to public health, devastate natural resources, disrupt economy • Bay of Campeche of Cuidad del Carmen, Mexico. (1997) • The accident resulted in spilling of 140 million gallons of oil • Northwest Spain (2002) • Tanker split in two • 70,000 tons of oil • Exxon Valdez • 1989 • 11 million gallons were spilled • 300-400 spills in Alaska

  5. Effects of Oil Spills • Marine Contamination • Contaminated sea surface, unpleasant smells and tastes to aquatic life, death • Impair ability to reproduce, grow, feed • Contaminates Rocks, sand, and mud areas • Oil covered fur or feathers can’t insulate • Oil breaks down a bird’s waterproofing • Animals clean itself, swallow oil

  6. Methods of Cleaning • Bioremediation- use of microorganisms to break down oil • Burning, dredging, skimming • Dispersants- act as detergent • Take months or years to clean up • Collection centers
