“…The concentrations of air pollutants are closely related to meteorological conditions (Nguyen et al, 2019;Zhang et al, 2019c;Chen et al, 2018a). An important aspect in assessing air quality improvement is to consider the impact of meteorology Vu et al, 2019).…”

Highlights： 1. The air quality of Beijing before and after two action plans was assessed.2. SO2 decreased the most, followed by CO, PM2.5, PM10, and NO2, while O3 increased slightly.3. The control of coal consumption played a dominant role in pollutant reduction.4. The influences from meteorology, pollutant emissions, and energy structure were evaluated.5. The control measures have proved to be effective in improving Beijing's air quality.

“…Southeast Asia (SEA) is strongly affected by atmospheric haze pollution (Wiriya et al, 2013;(Li and Shao, 2009;Pongpiachan et al, 2014a;Pongpiachan et al, 2015;Chuang et al, 2016;Li et al, 2016;Chomanee et al, 2020;Dejchanchaiwong et al, 2020;ChooChuay et al, 2020a;ChooChuay et al, 2020b;ChooChuay et al, 2020c;Dejchanchaiwong and Tekasakul, 2021). In the upper SEA, the haze is observed during a quarter of every year and studied, mostly in Thailand (Wiriya et al, 2013;Wiriya et al, 2016;Thepnuan et al, 2019;Pani et al, 2019), but recently, air quality affected by PM10 and PM2.5 was studied in Laos (Nguyen et al, 2019), Myanmar (Sricharoenvech et al, 2020) and Vietnam (Le, 2020). Previous investigations showed that aerosol particles in northern Thailand originated from biomass burning both transboundary and domestic sources (Wiriya et al, 2013).…”

Northern Thailand has long been severely affected by haze from biomass burning containing fine and ultrafine aerosols in the dry period. The carbonaceous PM0.1 comprising elemental carbon (EC) and organic carbon (OC) collected during the haze and non-haze periods in Chiang Mai, Thailand was investigated. The PM0.1 levels during the haze periods were about 3 times higher than the non-haze periods, a significant increase. PM0.1 concentration was strongly correlated with atmospheric relative humidity and the number of forest fire hotspots. Carbonaceous aerosol characteristics in PM0.1 were analyzed with the thermal/optical transmittance (TOT) method

“…Thus, poor air quality could potentially be a major constraint for bee foraging and ultimately their contribution to pollination. Especially, climate change‐induced air pollution over South Asia and Southeast Asia is projected to deteriorate air quality in future (Kumar et al, 2018; Nguyen et al., 2019). Moreover, agricultural production in those continents and their countries is highly dependent on pollination service (Potts et al., 2016).…”

Increased concentration of airborne particulate matter (PM) in the atmosphere alters the degree of polarization of skylight which is used by honeybees for navigation during their foraging trips. However, little has empirically shown whether poor air quality indeed affects foraging performance (foraging trip duration) of honeybee. Here, we show apparent increases in the average duration of honeybee foraging during and after a heavy air pollution event compared with that of the pre‐event period. The average foraging duration of honeybees during the event increased by 32 min compared with the pre‐event conditions, indicating that 71% more time was spent on foraging. Moreover, the average foraging duration measured after the event did not recover to its pre‐event level. We further investigated whether an optical property (Depolarization Ratio, DR) of dominant PM in the atmosphere and level of air pollution (fine PM mass concentration) affect foraging trip duration. The result demonstrates the DR and fine PM mass concentration have significant effects on honeybee foraging trip duration. Foraging trip duration increases with decreasing DR while it increases with increasing fine PM mass concentration. In addition, the effects of fine PM mass concentration are synergistic with overcast skies. Our study implies that poor air quality could pose a new threat to bee foraging.
