      article
      Currently, only the mass of sub 2.5 μm and sub 10 μm particles (PM2.5, PM10) in ambient air is regulated and monitored closely, but the same increase in PM2.5 can cause different degrees of health effects in different ...

    • Effect of Operation Pressure on the Response of ePNC Particle Number Concentration Sensor 

      Laakkonen, Elmeri; Arffman, Anssi; Rostedt, Antti; Keskinen, Jorma (20.11.2023)
      article
      In this article, we present a method that aims toward an ideal number concentration response of a diffusion charger and diffusion collector-based particle sensor (Dekati ePNC) by using reduced pressure conditions in the ...

    • Elemental analysis of single ambient aerosol particles using laser-induced breakdown spectroscopy 

      Heikkilä, Paavo; Rostedt, Antti; Toivonen, Juha; Keskinen, Jorma (2022)
      article
      Analysing the composition of aerosol particles is essential when studying their health effects, sources and atmospheric impacts. In many environments the relevant particles occur in very low concentrations, meaning that ...

    • Fuel‐operated auxiliary heaters are a major additional source of vehicular particulate emissions in cold regions 

      Karjalainen, Panu; Nikka, Markus; Olin, Miska; Martikainen, Sampsa; Rostedt, Antti; Arffman, Anssi; Mikkonen, Santtu (09 / 2021)
      article
      Fuel‐operated auxiliary heaters (AHs) can be notable sources of particle emissions from vehicles. The emissions of AHs are unregulated, and the number of devices is high; therefore, they make considerable contributions to ...

    • High-volume evacuation mitigates viral aerosol spread in dental procedures 

      Malmgren, Rasmus; Välimaa, Hanna; Oksanen, Lotta; Sanmark, Enni; Nikuri, Petra; Heikkilä, Paavo; Hakala, Jani; Ahola, Aleksi; Yli-Urpo, Simeoni; Palomäki, Ville; Asmi, Eija; Sofieva, Svetlana; Rostedt, Antti; Laitinen, Sirpa; Romantschuk, Martin; Sironen, Tarja; Atanasova, Nina; Paju, Susanna; Lahdentausta-Suomalainen, Laura (2023)
      article
      Dental healthcare personnel (DHCP) are subjected to microbe-containing aerosols and splatters in their everyday work. Safer work conditions must be developed to ensure the functioning of the healthcare system. By simulating ...
