摘要：

Due to the pandemic of SARS-CoV-2 in Croatia, all unnecessary activities were prohibited during the designated lockdown period (March-May 2020). With reduced human activity, levels of some air pollutants decreased. In this study, mass concentrations of the PM(1)particle fraction (particulate matter with an equivalent aerodynamic diameter < 1 mu m) and polycyclic aromatic hydrocarbons (PAHs) in PM(1)and NO(2)were measured and compared with concentrations measured in the same period the year before. Air pollutant concentrations were measured at two measuring sites: urban residential and urban traffic. Our results show a concentration decrease by 35% for NO(2)and PM(1)particles and by 26% for total PAHs at the traffic measuring site. At the residential measuring site, only concentrations of NO(2)decreased slightly, but PM(1)particles and PAHs were similar to the year before.
