   What are ultrafine particles?

   • Ultrafine particles (UFPs) are all particles with a diameter of 100nm or less. Most nucleation mode particles and the fraction of accumulation mode particles are UFPs. Fig. 3: Deposition of particles according to size distribution. Ultrafine particles are rapidly deposited by Brownian diffusion, especially particles <20 nm.

   Are ultrafine particles toxic?

   • The problem of ultrafine particles (UFPs; PM 0.1) has been prevalent since the past decades. In addition to become easily inhaled by human respiratory system due to their ultrafine diameter (<100 nm), ambient UFPs possess various physicochemical properties which make it more toxic. These properties vary based on the emission source profile.

   What are the physicochemical properties of ambient ultrafine particles?

   • Physicochemical properties of ambient ultrafine particles. As a matter of fact, UFPs PNC is often higher than that of bigger PM. This indicated that with the increasing value of surface area, the adsorption rate of other polluting elements such as organic gases and potentially toxic elements is also increased.

   Ultrafine particles (UFPs) are particulate matter of nanoscale size (less than 0.1 μm or 100 nm in diameter). Regulations do not exist for this size class of ambient air pollution particles, which are far smaller than the regulated PM 10 and PM 2.5 particle classes and are believed to have several more aggressive health implications than those ...
