Traffic congestion is one of serious problems in cities; rainfalls would exacerbate traffic congestion, and thus result huge economic losses. However, limited studies focused on how influenced its associated Based detailed hourly data, we estimated index (TCI) changed with different rainfall intensities the Beijing-Tianjin-Hebei (BTH) region, also explored their The results illustrated that all...

Under the Air Pollution Prevention and Control Action Plan (APPCAP) implemented, China has witnessed an air quality change during past five years, yet main influence factors remain relatively unexplored. Taking Beijing-Tianjin-Hebei (BTH) Yangtze River Delta (YRD) regions as typical cluster cities, Weather Research Forecasting (WRF) Comprehensive Quality Model with Extension (CAMx) were introdu...

Atmospheric aerosol pollution has seriously affected the ecological environment and human health in recent years. There are great differences optical properties types due to influence of environmental conditions, meteorology, industrial agricultural activities, other factors each functional zones. Using MODIS products (including MCD19A2 MOD04_3K), this study discussed temporal spatial distribut...

Given the advantages of remote sensing, an increasing number satellite aerosol optical depths (AOD) have been utilized to evaluate near-ground PM2.5. However, spatiotemporal relationship between AODs and PM2.5 still lacks a comprehensive investigation, especially in some regions with severe pollution within China. Here, we investigated relationships several near-surface concentration across Chi...

Abstract. Within a short time after the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, Hubei, Chinese government introduced nationwide lockdown to prevent spread pandemic. The quarantine measures have significantly decreased anthropogenic activities, thus improving air quality. To study impacts caused by on specific source sectors and regions Yangtze River Delta (YRD), Community Mult...

Bouvardia ternifolia (Cav.) Schltdl. is a shrub that belongs to the Rubiaceae family and distributed throughout México; it has been used for its antioxidant, neuroprotective, anti-inflammatory properties. This work aimed evaluate protective effects of B. root extracts on blood-brain barrier positive regulation cytokines IL-1β, IL-6, TNF-α, characterization compounds present in dichloromethane (...

Understanding the spatiotemporal heterogeneity and complex drivers of PM2.5 concentration variations has important scientific value for sustainable urban development. Taking Beijing-Tianjin-Hebei (BTH) as research area, using spatial analysis techniques wavelet methods to explore in concentrations, shows that past six years (2015–2020), concentrations BTH area have a downward trend, mean is 59....
