“When you would say the air is polluted?”, everybody thinks that when it mixes with chemicals. Actually, in physic and chemistry, when airs mixture is different then we say it’s polluted. But, today, air pollution is the introduction of chemicals, particulate matter or biological materials that cause harm or discomfort to our environment. And material which is causing the air pollute is pollutant. Pollutants can be in form of solid particles, liquid droplets and gas. And I think we can classify air pollution in three ways.
1. Man-made and natural:
This world is becoming more and more terrible because of humans invention, discovery and development. As example, one of the humans greatest invention and discovery, fuel is making the air polluted. When we burn the fuel it becomes COx.
And nature itself is making the air pollute. Because of volcanic eruption, many heavy metals become gas and liquid and pollutes air.
2. Primary and secondary:
Usually, primary pollutants are substances directly emitted from process. Such as, CO2 from burning fossil fuel, CO from motor vehicle exhaust and SO2 from factories.
Secondary pollutants are not emitted directly. They form in the air when primary react or interact. An important example of secondary pollutants is ground level ozone- one of the many secondary pollutants that make up photochemical smog.
There are many sources of air pollution. But we can classify into two major categories.
1) Anthropogenic source which means human activity:
This includes chemical materials which is created after burning coal, fuel, gas and others.
2) Natural source
Because earth is becoming warmer and warmer, there are places which is drying and lacking of vegetation.
There are many affects of air pollution. As example, doctors say that in our age and in our air pollution, almost everybody isn’t healthy. Especially, in Mongolia, they say that children are...
