FAQ air pollution Frequently Asked Questions
The question library on air related issues
What is air pollution?
Air pollution means the presence of one or more unwanted substances in air. Air pollutants have a negative impacts on humans, animals and plants, and on air quality.
The most frequently present categories of air pollutants are sulphur oxides, nitrogen oxides, Volatile Organic Compounds (VOC) and small dust particles (aerosols).
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.
Examples of large-scale air pollutants are VOC (Volatile Organic Compounds) and small dust particles. When large concentrations of these substances are emitted this negatively affects ecosystems, materials and public health.
Emissions of nitrous oxide (N2O) mainly stem from agriculture, because nitrogen in soils can easily be denitrified by bacteria. Nitrous oxide is emitted during the denitrification process. Additionally, the application of (artificial) fertilizers causes emissions of ammonia (NH3), nitrogen oxides (NOx) and methane CH4), a greenhouse gas.
The agricultural sector is known for its extensive use of pesticides. This application causes emissions of many toxic chemicals.

Nitrogen oxides are gasses that react with other air pollutants when they are present in air. ... VOC play an important role in ozone shaping in the lower atmospheric layer, the main cause of smog. VOC can cause various health effects, depending on the kind of compounds that are present and their concentrations.
