Benzotriazole (BTR) and benzothiazole (BTH) derivatives are used in a wide variety of industrial and consumer products and have been reported to occur in the environment. Owing to a lack of analytical methods, human exposure to BTRs and BTHs is still unknown. Therefore, a liquid chromatography-electrospray ionization tandem mass spectrometry (LC–ESI(+)MS/MS) method was developed for simultaneou...

In recent years, ozone (O3) concentration has shown a decreasing trend in the Beijing–Tianjin–Hebei (BTH) region China. However, O3 pollution remains prominent problem. Accurate estimation of exposure levels can provide support for epidemiological studies. A total 13 variables were combined to estimate short- and long-term using geographically weighted regression (GWR) model BTH with spatial re...

Extreme heat events are frequent in the Beijing–Tianjin–Hebei (BTH) region due to global warming and accelerated urbanization. While previous studies have analyzed trend of extreme region, interdecadal changes these remain unclear. Therefore, this study aims analyze temporal spatial characteristics summer BTH using daily mean maximum temperature datasets from 174 stations over period 1979–2020....
