The viewpoints of chemical air pollution caused by traffic subsystems and presented by the example of emission measurements of trucks' exhaust gases

For a long time, experts have been emphasizing that we are in an era, in which dangerous climatic changes are getting more and more notable. We have been witnessing large climatic changes, caused by greenhouse gases, for several years. The question is no more “Are there climatic changes or are there not?”, nor “Are they being accelerated by human actions or are they not?” The fact is, the climate is changing more and more rapidly and that extreme weather conditions are becoming a daily matter. Furthermore, even if we stopped polluting the atmosphere immediately, the processes triggered by human-caused pollution would be going on for several decades. Modern logistic systems cannot operate without means of transport which enable the realization of transport. They form a transport system that makes the function of other economic systems possible. The use of different ways of transport has a bad influence on the environment in which we daily live and work. The damage of transportation has a bad influence on human health and nature, too. For that reason, we cannot treat the safety of the transportation means only through the technical impeccability of the devices which make possible direct execution of particular technological phases in different traffic subsystems. Ecological impacts of particular traffic subsystems are very complex, they have a long-term impact on our everyday existence and despite that we still do not devote enough attention to this. We have been aware that traffic, especially road and air traffic, is one of the largest sources of emissions of harmful exhaust gases of combustion engines and particles into the environment. The environmental impact of traffic is especially large due to greenhouse gases, which are part of exhaust gases being produced by internal combustion engines. In addition to that, there are many more toxic components in exhausted gases
