The coordinated development of atmospheric pollution and socio-economic growth plays a core role in the sustainable cities regions. relationship between air can be described using decoupling analysis. seven key regions China (168 cities), including Beijing–Tianjin–Hebei its surrounding areas (BTHSR), Yangtze River Delta region (YRDR), Fen-Wei Plain (FWP), Chengdu–Chongqing (CCR), urban agglomeration middle reaches (MLRYR), Pearl (PRDR), other provincial capitals municipalities with specialized plans (OPCCSP) were taken as targets to investigate spatiotemporal evolution characteristics AQI values PM2.5 concentrations from 2014 2022. Then, AQI/PM2.5 index (SEGI) these was deeply researched by Tapio model. main results follows: (1) Although continuous improvement quality observed China, concentration BTHSR FWP still higher than 35 μg·m−3. showed spatial pattern high north low south, distribution east west.

To explore the characteristics of PM2.5 and assess health risks to residents in Shijiazhuang before during heating period 2019, 2020 2021, hourly concentrations its nine selected trace elements were determined. The results showed that mass 80.32 ± 50.21 μg m-3 (2019), 69.97 41.91 (2020) 58.70 41.97 (2021) period, representing greatly improved air quality. levels 1.04~1.60 times greater than those while total element about 1.44~1.97 higher, indicating strict control for should be imposed. overall hazard quotient (HQ) 1.08~1.42 higher cancer (CR) decreased by 29.04% 3.50% (2021). There high not only local areas, but also south Hebei, north Henan, southern central Shanxi. increased 1.21~2.26 from clean heavy pollution levels. leading HQ was Mn, dominant CR varied As Co. Increases observed, there even an inverse change between further identifying efficient.
