Nowadays air pollution is a huge problem which has influence on people?s health and wellness. The air that we breathe is highly important because it is one of component of good functional out organisms. While we want to keep air fresh we need to do something with pollution sources that's why people started thinking about it a while ago.

One of the variety air pollution is classical air pollution what includes nitrogen dioxide, ozone, particulate matter, sulfur dioxide SO2 (which is not stable, it produced during coal combustion for instance, the sulfur dioxide from Germany, Spain, Ukraine and Czech Republic brought to the north) and other photochemical oxidants.

Therefore convention on long-range transboundary air pollution accepted, the aim of the convention was to limit, reduce and prevent air pollution. Member states of CLRTAP had to reduce about 30% by year 1993. Although the assignment of limiting air pollution was difficult for execution nobody didn?t demand from members realization those conditions however member states tried to do their best for reducing air pollution.

Today the aim of convention on long-range transboundary air pollution mostly is to introduce other countries and regions as East Europe, Caucasus, Central Asia and others.
