What is soot pollution

  • Soot pollution, also known as fine particulate matter (PM2.5).

  • Its a dangerous form of air pollution made up of tiny particles and droplets.

  • They are 2.5 micrometers or less in diameter.

  • These particles are so small that they can easily enter your lungs and even deeper into your bloodstream, where they can cause a variety of health problems. 

  • Sources: Soot pollution comes from a variety of sources, including the burning of fossil fuels (coal, oil, and gas), wildfires, and industrial processes.

  • Health effects: Exposure to soot pollution can lead to a variety of health problems, including respiratory problems, heart disease, stroke, lung cancer, and premature death.

  • Regulation: The Environmental Protection Agency (EPA) sets national air quality standards for PM2.5. 

  • These standards have been tightened over time, but soot pollution remains a major public health problem.

  • Soot pollution is a global problem, but it is particularly severe in developing countries, where air quality standards are often weaker.

  • Soot pollution can also contribute to climate change by absorbing heat from the sun.

  • There are a number of things that can be done to reduce soot pollution, such as using cleaner fuels, improving energy efficiency, and reducing wildfires.
