Atmospheric hydrogen peroxide (H2O2) plays an important role in sulfate formation. To explore the contribution of H2O2 oxidation pathway to atmospheric winter Beijing, three field campaigns measurements were conducted at urban site (Beijing) and a rural (Wangdu) during 2016, 2017, 2018. The concentrations usually around detection limit (0.05 ppbv) clean severely polluted periods, whereas highest concentration 0.90 ppbv was observed moderately periods. Obvious increases could be after sunset...
Abstract. Atmospheric non-methane hydrocarbon compounds (NMHCs) were measured at a sampling site in Beijing city from 15 December 2015 to 14 January 2016 recognize their pollution levels, variation characteristics, and sources. We quantified 53 NMHCs, the proportions of alkanes, alkenes, acetylene, aromatics total NMHCs 49.8–55.8, 21.5–24.7, 13.5–15.9, 9.3–10.7 %, respectively. The trends NMHC concentrations basically identical exhibited remarkable fluctuation, which was mainly ascribed...
Abstract. A vast area in northern China, especially during wintertime, is currently suffering from severe haze events due to the high levels of atmospheric PM2. 5. To recognize reasons for 5, daily samples 5 were simultaneously collected at four sampling sites Beijing city (BJ), Baoding (BD), Wangdu county (WD) and Dongbaituo (DBT) winter spring 2014–2015. The concentrations typical water-soluble ions (WSIs, such as Cl−, NO3−, SO42− NH4+) DBT found be remarkably higher than those BJ two...
Abstract. The North China Plain (NCP), which includes Beijing, is currently suffering from severe haze events due to a high pollution level of PM2.5. To mitigate the serious problem, identification sources PM2.5 urgently needed for effective control measures. Daily samples were collected in Beijing city and rural area Baoding, Hebei Province through year 2014, seasonal variation water-soluble ions (WSIs) was comprehensively analysed determine their possible sources. results indicated that...
Recently, deteriorating ozone (O3) pollution in China brought the precise diagnosis of O3 sensitive chemistry to forefront. As a dominant precursor OH radicals, atmospheric nitrous acid (HONO) plays an important role production. However, its measurement unavailability many regions especially for second- and third-tier cities may lead misjudgment sensitivity regime derived from observation-based models. Here, we systematically assess potential impact HONO on diagnosing production using...
Abstract Carbonyl sulfide (COS), carbon monoxide (CO), and sulfur dioxide (SO 2 ) emissions generated from prevailing domestic coal stoves fueled with raw bituminous were studied under alternation cycles of flaming smoldering combustion. The measurements in the laboratory farmer's house indicated that COS CO mainly occurred condition flame extinguishment after loading, whereas SO through combustion flame. emission factors for recorded as 0.57 ± 0.10 g kg −1 1.43 0.32 , being approximately a...
Tidal flats form boundaries between marine and terrestrial environments, reported rapid decreases in their extent require improved measures of status. Current methods for delineating tidal have low accuracy because the limited precision available imagery, they cannot identify zones within flats. Three are ecologically distinct due to varied inundation. These include supratidal, intertidal, subtidal zones. In this study, we present a more precise method mapping We used Chinese HJ-1A/B...
