Fine and Ultrafine Particles in a Supermarket in Sweden

The aim of this study was to gain information about fine and ultrafine particles (diameter smaller than 2.5 μm and 100 nm, respectively) loads and their characteristics in a supermarket in Sweden. Assessed particles ’ characteristics are: number and mass concentrations and number size distributions. In the studied supermarket, an indoor source of ultrafine particles was observed, most probably due to local emissions of terpenes (from washing powders, cleaning products and air fresheners), which in the presence of ozone from outdoors form particles due to gas-to-particle conversions.
