FAQ air pollution Frequently Asked Questions
The question library on air related issues
What is air pollution?
What causes air pollution?
The main sources of air pollution are the industries, agriculture and traffic, as well as energy generation. During combustion processes and other production processes air pollutants are emitted. Some of these substances are not directly damaging to air quality, but will form harmful air pollutants by reactions with other substances that are present in air.
How does air pollution form?
Air pollution can form in various ways. Chemicals are emitted during many different human activities. In the atmosphere these chemicals can react with other chemicals to more dangerous substances. Air pollutants often have properties that are harmful to the environment.
What types of air pollution are there?
Air pollution consists of gases and/ or particles. These have a distinct chemical or physical structure, or a distinct effect on human health.
What are the main environmental effects of air pollution?
Here, we will sum up and briefly explain the main environmental effects of air pollution:

The best circumstances for the creation of high ozone concentrations are summer temperatures, direct sunlight and standing air layer, which enable dilution of contaminants.
The Greenhouse effect (GE)
In the following table we can see which air pollutants are involved in various environmental problems.
How does air pollution spread and how can we handle this?
The dispersion of air pollutants mainly depends on physical processes is air; those of wind and weather. How far air pollutants are transported mainly depends upon particle size of the compounds and at which height the pollution was emitted into the air. Fumes that are emitted into air through high smoke stags will mix with air so that local concentrations are not very high. However, wind will transport compounds and the pollution will become very disperse. Rain can remove pollutants from air. This causes precipitation and consequentially soil and water pollution.
