An international measurement campaign has begun at the university to study the health hazards of particulate emissions and air pollution from aircraft turbines and marine engines. The measurements take place within the framework of the ULTRHAS project (ULtrafine particles from TRansportation - Health Assessment of Sources). The project is funded by the EU with more than 4 million euros. Photo: Bernd Wüstneck/dpa. - Rostock/Mecklenburg-Western Pomerania/Germany
