Analysis of the particle size distribution near the civil airport runway

Particles emitted from internal combustion engines are extremely dangerous to human health due to their very small size. Attempts to reduce particles emissions from motor vehicles, result in the installation of additional filters to purify the exhaust gases. In the case of aircraft, any interference in the exhaust system of the jet engine is unacceptable. For this reason, aircraft are an important source of particles emission in the regional aspect, so that airports can be considered as particles emission sources. The article evaluates the impact of aircraft take-off and landing operations on the concentration of particles in the ambient air. The measurements were carried out at the civilian airport area near the runway. Based on the measurements carried out, it was found that airport operations cause relevant changes in the concentration and size distribution of particles in the ambient air. (paper)
