“…However, the SO 2 and O 3 levels did not significantly improve. Similar results were also obtained by Cao et al (2022) and Agarwal et al (2020) . In this study, negative AOD and PM 2.5 anomalies occurred in February 2020 relative to 2019.…”

“…Similarly, decreases in fine particles (PM 2.5 ) and CO were observed due to factory production and traffic restrictions ( Alqasemi et al, 2021 ; Hidalgo García and Arco Díaz, 2022 ; Jamei et al, 2022 ). In contrast, the change in SO 2 was ambiguous ( Hidalgo García and Arco Díaz, 2022 ; Tyagi et al, 2021 ), and even the opposite trend in O 3 was observed ( Cao et al, 2022 ). However, the air quality in some economically underdeveloped areas has not been improved because of the COVID-19 lockdowns ( Mandal et al, 2022 ; Martinez-Soto et al, 2021 ).…”

“…The world economy has reportedly shrunk by 13–32 % due to the pandemic ( Mousazadeh et al, 2021 ), and despite digital teaching efforts, >1 billion students did not receive normal education ( Shulla et al, 2021 ). In addition, the restrictions on public transport, industrial production, human activities, and social distancing have led to global environmental changes ( Lal et al, 2020 ), such as air pollution and urban thermal environmental changes ( Cao et al, 2022 ; Chakraborty et al, 2021 ). This also provides the opportunity to study the environmental impacts of notable human interference.…”

“…During the worldwide urban lockdown, a significant decrease in the daily NO 2 concentration of 3–58 % was observed ( Benchrif et al, 2021 ). Notable declines were widely observed in China ( Agarwal et al, 2020 ), Pakistan ( Ali et al, 2021 ), Germany ( Cao et al, 2022 ), France ( Kovács, 2022 ), Malaysia ( Abdullah et al, 2020 ), Chile ( Toro et al, 2021 ), and the USA ( Bekbulat et al, 2021 ).

“…This method did not consider the influence of climate factors and social factors (e.g., weekends) on pollutant concentrations, which will bring some deviations to the research results. Some studies predicted pollutant concentrations in the business as usual (BAU) scenario using the multiple linear regression (MLR) and random forest (RF) and compared the predicted results with the observed concentrations during COVID-19 lockdown (Cao et al, 2022 ; González-Pardo et al, 2022 ). However, the predicted results are not very accurate, which may result in inaccurate conclusions.…”

The Omicron pandemic broke out in Shanghai in March 2022, and some infected people spread to some cities in the Yangtze River Delta (YRD) region. To achieve the dynamic zero-COVID target as soon as possible, Shanghai and nine cities that were heavily affected by Shanghai implemented the lockdown measures. This paper aims to quantify the impact of the lockdown on air quality and human health. A difference-in-difference (DID) model was first used to measure the impact of the lockdown on air quality in these ten cities. Based on the results of the DID model, we estimated the PM 2.5 -related health and economic benefits using the concentration–response function and the value of statistical life method. Results showed that the lockdown has reduced the concentrations of PM 2.5 , PM 10 , SO 2 , NO 2 , and CO by 9.87 μg/m 3 , 17.31 μg/m 3 , 0.75 μg/m 3 , 9.03 μg/m 3 , and 0.07 mg/m 3 , respectively. The number of avoided premature deaths due to PM 2.5 reduction was estimated to be 35,342. The resulting economic benefits totaled 18.86 billion US dollars. We investigated the reasons for the air quality improvement in these ten cities and found the “3 + 11” policy has had a great impact on air quality. Compared with the first COVID-19 lockdown in early 2020, the effect of the lockdown in 2022 was smaller. These findings demonstrated that reductions in anthropogenic emissions would achieve substantial air quality improvement and health benefits. This paper re-emphasized continuous efforts to improve air quality are essential to protect public health.

Pollen production is one plant characteristic that is considered to be altered by changes in environmental conditions. In this study, we investigated pollen production of the three anemophilous species Betula pendula, Plantago lanceolata, and Dactylis glomerata along an urbanization gradient in Ingolstadt, Germany. We compared pollen production with the potential influencing factors urbanization, air temperature, and the air pollutants nitrogen dioxide (NO2) and ozone (O3). While we measured air temperature in the field, we computed concentration levels of NO2 and O3 from a land use regression model. The results showed that average pollen production (in million pollen grains) was 1.2 ± 1.0 per catkin of Betula pendula, 5.0 ± 2.4 per inflorescence of Plantago lanceolata, and 0.7 ± 0.5 per spikelet of Dactylis glomerata. Pollen production was higher in rural compared to urban locations on average for B. pendula (+ 73%) and P. lanceolata (+ 31%), while the opposite was the case for D. glomerata (− 14%). We found that there was substantial heterogeneity across the three species with respect to the association of pollen production and environmental influences. Pollen production decreased for all species with increasing temperature and urbanization, while for increasing pollutant concentrations, decreases were observed for B. pendula, P. lanceolata, and increases for D. glomerata. Additionally, pollen production was found to be highly variable across species and within species—even at small spatial distances. Experiments should be conducted to further explore plant responses to altering environmental conditions.
