Which things make pollution in air?
Air pollution can result from both human and natural actions. Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity. Pollution from natural occurrences is not very often.

Measures and solutions:
- Vacuum cleaning and sprinkling of water on all roads.
- Focus a team on decreasing the dust from construction sites, outside houses, parks and generator gases.
- A lot of air and truck sprinkling of water everywhere.
- Controlled burning at the landfill sites using piping and venting to reduce uncontrolled toxic emissions at source
- Obtain methane gas and covering of landfills with inert material and alum sludge from water treatment plants
- The vacuum cleaning of roads. Jet pressure pump technique should be used for water sprinkling on footpath edges, road bumps and central verges. This can control dust particles.
- Install new mist fountains and air purifiers like Punjab did important traffic intersections and busy shopping mall areas.
