The measurement of volatile organic compounds (VOCs) was conducted during November 2014 in the suburban area Beijing, China, covering period Asia-Pacific Economic Cooperation (APEC) meeting period. VOCs characteristics and source apportionment were analyzed. average mass concentrations 27.6 ± 19.7 μg/m3 sampling period, aromatics alkanes most abundant species atmospheric environment Beijing which 12.2 10.3 11.3 7.5 μg/m3, respectively. hourly variation found, with highest concentration...
Z-scheme heterojunction Bi2WO6/g-C3N4 was obtained by a novel hydrothermal process; its photocatalysis–persulfate (PDS) activation for tetracycline (TC) removal explored under solar light (SL). The structure and photoelectrochemistry behavior of fabricated samples were well characterized FT-IR, XRD, XPS, SEM-EDS, UV-vis DRS, Mott-Schottky, PL, photocurrent response, EIS BET. critical experimental factors in TC decomposition investigated, including the Bi2WO6 doping ratio, catalyst dosage,...
In order to investigate the chemical characteristics of aerosol pollution including PM1 and PM2.5 in Handan, offline sampling campaign was conducted concentrations total water-soluble inorganic ions (TWSI), carbonaceous components (OC EC) were analyzed. The average 88.5 μg/m3 for 122 PM2.5, corresponding ratios versus on non-pollution, mild-moderate heavy 0.67, 0.70 0.77, respectively. TWSI OC accounted 43.2% 15.4% PM1, 41.8% 16.0% PM2.5. Secondary increased with pollution, SNA (SO42−, NO3−...
BiOCl/graphene aerogel graphene (BGA) was successfully obtained by in situ hydrothermal synthesis, and the chemical, structural, morphological, photocatalytic properties were systematically characterized. BGA with doping amount of BiOCl at 20% (BGA-4) exhibited optimal activation efficiency for persulfate (PDS) on degradation methyl orange (MO) under simulated sunlight (SSL) illumination as compared to pure (GA) composites different content. The influence various reaction parameters MO...
Temporal and spatial distribution characteristics of PM2.5 transport fluxes between Beijing its adjacent cities in July October 2016 were estimated quantitatively using the cross-boundary flux method based on WRF-CMAQ model this study. Vertical net was revealed, hourly evolution typical heavy pollution processes illustrated. We verified significant seasonal differences during study period. total inflow outflow autumn 3187 t/d -2721 t/d, which significantly higher than that 2134 -2172 summer....
The pollution characteristics of surface ozone and its response to meteorological factors precursors were studied based on monitoring Model-3/CMAQ modeling from May August 2018 in Handan City, China. results showed that the maximum daily 8-hour average concentration (MDA8 O3) ranged 38.0-238.0 μg·m-3, nonattainment for reached 44.7% during period, indicating more severe photochemical summer City. was positively correlated with temperature (R=0.74 days 0.42 attainment days), but negatively...
In order to explore the pollution characteristics, seasonal variations, and sources of water-soluble inorganic ions (WSIIs) in PM2.5 Zhengzhou, samples were seasonally collected from December 2020 October 2021; then, combining gaseous pollutants (SO2, NO2, O3) meteorological parameters (temperature relative humidity), nine WSIIs (NO3-, NH4+, SO42-, Ca2+, K+, Na+, Mg2+, F-, Cl-) analyzed. The results showed that annual average concentration total (TWSIIs) was (39.34±21.56) μg·m-3for four...
This paper was the first to employ land use regression (LUR) with high-resolution geographical census data for Hebei, one of most severely polluted regions in China, evaluate its spatial distribution characteristics PM2.5 and NO2 concentrations identify influencing factors.To develop LUR model, recorded at 53 sites Hebei were selected as dependent variables.Independent variables include buffer-related location-based factors.At first, 169 independent chosen total.Then pre-processing bivariate...
