AbstractAir pollution is an important anthropogenic hazard due to its effect on human health and the environment. Understanding how the population perceives the risk associated with air pollution is a crucial aspect to inform future policies and communication strategies. The aim of this study is to examine the association between air pollution concentrations and public risk perception of air pollution, also exploring socio-demographic patterns in the general population of Italy and Sweden. To this end, we derived 3-year PM10 average concentrations from ground monitoring stations and integrated with a population-based survey carried out in August 2021 in both countries. Relative perceived likelihood and impact on the individual were considered as domains of risk perception. In addition this, information on direct experience and socio-demographic factors were included as possible determinants of risk perception. Linear regression models were performed to examine the association of PM10 average concentrations at regional level and individual level factors with risk perception domains. In both countries, respondents who live in the most densely populated regions report a higher perceived likelihood of air pollution. Direct experience is the main driver of risk perception in both countries. Being male and smokers in Italy, older age and having left/centre-left political orientation in both countries are associated with a higher perceived likelihood and impact of air pollution. These findings will inform future health and environmental studies regarding the public risk perception of air pollution highlighting individual's awareness and the socio-demographic patterns.Copyright © 2023 The Authors.
