Development of sampling protocols and methods for extracting appropriate representative materials for in vitro and in vivo analyses. Develop detailed guidelines for regulators and airports for measuring and modeling aircraft engine emissions and their dispersion, with particular attention to FPU, VOCs and VOCs. Establish interdependencies in the air quality causal chain that better links current methods of certification of engine emissions with local air quality regulations for health protection. “Living in a good environment, within the borders of our planet, recognises the EU`s long-term goal of achieving air quality levels that do not lead to significant negative effects and risks to human health and the environment.” Measure, quantify and characterize the polluting emissions of aircraft engines below the parking space (with operational APU), taxi, approach, take-off and slope. , NOx, SOx and VOC in different climatic conditions. Development of the understanding of the main engine and the evolution of the APU exhaust gas pen, dispersion, microphysis and chemistry. Improve the ability of existing dispersal models to describe the impact of aircraft emissions on air quality at airports and surrounding areas.
