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 PM1 particle fraction (particulate matter with an equivalent aerodynamic diameter < 1 μm) and polycyclic aromatic hydrocarbons (PAHs) in PM1 and NO2 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 NO2 and PM1 particles and by 26% for total PAHs at the traffic measuring site. At the residential measuring site, only concentrations of NO2 decreased slightly, but PM1 particles and PAHs were similar to the year before.

由 COVID-19 大流行引起的封锁对克罗地亚观察到的空气污染和颗粒物致癌含量的影响
由于 SARS-CoV-2 在克罗地亚大流行,在指定的封锁期间(2020 年 3 月至 2020 年 5 月)禁止所有不必要的活动。随着人类活动的减少,一些空气污染物的水平下降。在本研究中,测量了 PM1 和 NO2 中 PM1 颗粒组分(当量空气动力学直径 < 1 μm 的颗粒物)和多环芳烃 (PAHs) 的质量浓度,并与去年同期测量的浓度进行了比较。在两个测量点测量空气污染物浓度:城市住宅和城市交通。我们的结果显示,在交通测量点,NO2 和 PM1 颗粒的浓度降低了 35%,而总 PAHs 的浓度降低了 26%。在住宅测量点,只有 NO2 浓度略有下降,
