How do we measure air pollution?
  • Scientists use special equipment to test the air for pollution.
  • They use machines to capture different gases and then they measure the gases to see how much of it is in the air.
  • Other machines are used to catch tiny solid particles in the air called particulates. These particulates can be dirt, smoke or even pollen from plants.
  • These tiny flecks of dirt are so small that scientists need to use a strong microscope if they want to figure out what the different pieces are.
  • You can catch your own particulate pollution with the help of an adult, by doing Catch the Pollution activity.
