What is air pollution simple definition?

Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution.

What are the causes of air pollution in chemistry?

The Short Answer: Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.

What are called air pollutants?

These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides. Carbon Monoxide. Carbon Monoxide – ATSDR Toxic Substances Portal. Carbon Monoxide – EPA Website.

What is air pollution and its types?

The EPA identified six major types of air pollutants deemed especially harmful to human health. These are carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, particulate matter and lead. Since the Clean Air Act of 1970 and the identification of these pollutants, air pollution has decreased markedly.

  6. Plant and care for trees.
  7. Switch to electric or hand-powered lawn equipment.
  8. Use less energy.

What is the solution of air pollution?

Reducing energy consumption helps reduce air pollution. If less gasoline, natural gas and electricity (power plants burn fossil fuels to generate electricity) are used, not only do your bills decrease but less pollutants are emitted.

Which is the largest air pollutant?
