Corrigendum to “Effect of energy renovation and occupants' activities on airborne particle concentrations in Swedish rental apartments” [Sci. Total Environ. Volume 806, Part 1, 1 February 2022, 149995]

Exposure to airborne particles causes detrimental health effects, hence their assessment in indoor environments, where people spend most of the time, is important. The influence of energy renovation and occupants' activities on airborne particle concentrations was assessed in seven occupied Swedish residences. Ultrafine particle (UFP, <100 nm) number concentrations, PM2.5 (<2.5 μm) and black carbon (BC, <900 nm) mass concentrations were simultaneously measured inside and outside before, after renovation, and during follow-up.
