To identify the potential environmental pollution and health hazards of airborne nanoparticles, it is necessary to determine their physical and chemical properties and characteristics. An overview of the sampling and characterization techniques at VITO associated with the measurement of ultrafine and nano-airborne particle properties is shown.
