ِAir pollution

Air pollution occurs when gases, dust particles, fumes (or smoke) or odor are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant.

 What causes air pollution? 

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. Human activities that result in air pollution include:

1. Emissions from industries and manufacturing      activities: Waste incinerators, manufacturing industries and power plants emit high levels of carbon monoxide, organic compounds, and chemicals into the air.

  1. Burning Fossil Fuels: After the industrial age, transportation has become a key part of our lives. Cars and heavy-duty trucks, trains, shipping vessels and airplanes all burn lots of fossil fuels to work. Fumes from car exhaust contain dangerous gases such as carbon monoxide, oxides of nitrogen, hydrocarbons and particulates.


3. Household and Farming Chemicals: Crop dusting, fumigating homes, household cleaning products or painting supplies, over the counter insect/pest killers, fertilizer dusts emit harmful chemicals into the air and cause pollution
