“…Meteorology plays significant roles in air pollution formation, transport, deposition and transformation and unfavorable meteorological condition could bring severe pollution days even the total emission is reduced (Shi et al, 2018;Xu et al, 2016;Li et al, 2017c;Cai et al, 2018;Gui et al, 2019;Wang et al, 2019b). In the pollution period of December 20-26, 2015 in BTH region, about 34% increasing of PM 2.5 are believed due to adverse meteorological condition (Ma et al, 2020).…”

“…Three main haze transportation paths were summarized and the barrier function of high mountains to haze transportation was also pointed out [20]. Shi et al employed back-trajectory clustering analysis together with daily quality data, routine and reanalysis meteorological data, and some climate indices to investigate the transport paths, large-scale vertical motion and related climate background conducive to PM 2.5 pollution in the western Yangtze River Delta [21].…”

Besides local emissions, long-range transportation of polluted air masses also has a huge impact on haze pollution. In this study, the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used to determine the transport paths and potential sources of haze pollution in the Yangtze River Delta Urban Agglomeration. Haze days were determined by setting the threshold of meteorological elements. Shanghai, Hangzhou, Nanjing and Hefei were selected as four representative cities to calculate the −72 h backward transport trajectory of haze air mass; thus, the main transport path was obtained after clustering. A potential source contribution function and concentration weighted field were used to identify potential pollution sources of the study. The results showed that the number of haze days in the northern Yangtze River Delta Urban Agglomeration is much higher than that in the south. Haze days and Fine particulate matter (PM2.5) concentration showed a downward trend. The transport paths could be summarized as long-range transports from the northwest and coastal direction during the dry season and short-distance transports from all directions. −72 h air flow trajectories come from the higher altitudes in dry season than these in wet season. The main sources of potential pollution are Hebei, Shandong, Anhui and northern Jiangsu.

“…It should be noted that the women studied are of childbearing age and those who already have children, especially infants, these children remained in the same conditions. Studies have shown that in children living near high-traffic roads or in a dense road network, the health risk is very high because of their weak immune system (Frère et al, 2005;Hoffmann et al, 2006;Honoré et al, 2013;Shi et al, 2018). Increases in risk range from 20% to 100% depending on the health indicator, the exposure index and the population studied.…”

OBJECTIVE: Air pollution is now a public health concern and there is an urgent need to find local feasible solution to overcome the related health issues. Regarding outdoor air pollution effect on vendors health and workplaces exposed to high traffic, it is important to accurately define the most exposed between those working along main roads or in roundabouts with high traffic. The purpose of this study was to assess the vendors respiratory health risks associated with these different geographical positions in Cotonou. METHODS: A cross-sectional study was conducted and included all the shops along a main road and a roundabout with high traffic in Cotonou. One person was recruited per shop and was allocated a unique GPS data associated with the geographical position of its shop. Validated questionnaire on respiratory symptoms was administered to 194 individuals who were included. RESULTS: The mean (standard deviation) of age of workers was 36.26 (±11.65) years and the sex ratio (M/F) was 1.8. Most of respondents (69.07%) worked in non-ventilated rooms. 72.68% of the workers reported at least one respiratory symptom. This proportion was significantly different (p<0.001) between the subpopulations at roundabout (96.15%) and apart from the roundabout (64.08%). The most reported symptoms by the workers were respectively cough (47.94%), itchy nose (42.27%) and breathlessness (28.35%). The risk of cough and itchy nose symptoms were respectively 5.15 (OR=5.15; 95% CI= [2.21;12.04]; p< .001) and 3.44 (OR=3.44; 95% CI= [1.55;7.63]; p=0.002) higher in individuals working at the roundabout compared to those working along the main road. CONCLUSION: Working in roundabout is associated with more respiratory disorders than practicing in shop along a main road. In a resources limited settings, it may be important to focus air pollution mitigation effort on this subpopulation of workers.
