apes modules 43-45 - oil/water polllution

• Petroleum is toxic to organisms.
• Oil may enter water via drilling or natural seeps.
• Oil pollution remedies include containment, chemicals, or bioremediation.
• containment


  usage of booms and oil vacuums to clean up pollution
• How do chemicals ease oil pollution?

  breaks down surface oil
• bioremediation


  bacteria consuming oil
• What are the three types of oil pollution?

  sediment pollution, solid pollution, thermal pollution
• What is sediment pollution?

  soil particles and sediments are suspended in water, causing pollution
• 30% of sediment pollution is caused naturally while 70% is caused anthropogenically.
• Solid pollution occurs when garbage and sludge is dumped into the ocean.
• Thermal pollution

  anthropogenic activities that significantly increase water temperature
• Cooling towers reduce thermal pollution by sending excess heat to the atmosphere instead of water bodies.
• Noise pollution causes physiological stress and hearing loss, and it may cause memory impairment and attention issues in high-exposure children.
• Noise pollution interferes with an animal's natural use of sound.
• Noise pollution may disrupt organisms' ability to communicate, navigate, and find food.
• The Clean Water Act regulates surface water, while the Safe Water Drinking Act regulates surface and groundwater.
