“…The uncertainty and VOC emission estimated in the YRD region and China from different studies are presented in Table 6. Our findings were lower than those reported by Fu et al (2010), , and Wu et al (2016) but larger than those reported by Huang et al (2011). The results vary because of the different source classifications and areas covered in these studies.…”

A bottom-up inventory of atmospheric emissions of industrial MNVOCs in Yangtze River Delta (YRD) region was established for the period of 2010-2012. Results indicated that the total emissions of industrial VOCs increased from 3.34 Tg in 2010 to 3.99 Tg in 2012 at an annual average rate of 9.3%. Furniture manufacturing, machinery equipment manufacturing, architectural ornament, and petroleum refining were estimated to be the key sources, which contributed 58.6% of the total emissions in 2012. Based on the population database, the emission inventory was gridded into 1 km × 1 km grid cells with ArcGIS, which indicated that VOC emissions exhibited remarkable spatial and temporal characteristics. The most polluted areas were mainly centered in Shanghai, Nanjing, Ningbo, Hefei, and the Hangzhou and Taihu lake basin, which were the most developed and industrialized regions in the YRD. VOC emissions from specified anthropogenic sources under three different control scenarios for the different emission targets in 2030 were projected. The estimated average removal efficiency of the control technologies for each anthropogenic source should improve by 68.1% (scenario 2030B) and 79.0% (scenario 2030C). An entire process-control management scheme needs to be established based on the investigation of industrial processes, and the proportion of the application should be improved in the future.

“…It has been reported that biomass burning (including biofuel) contributed 14.1 % of the total VOC emissions in China during 2012, whereas in Anhui province the contribution of biomass combustion to VOC emissions was 28.7 % (Wu et al, 2016). B. reported that biomass burning contributed 58 % of OC in Nanjing, China during summer 2012, suggesting that biomass burning is the dominant source of OC in this region.…”

Abstract. Extensive forest fires occurred during late July 2014 across the forested region of Siberia, Russia. Smoke plumes emitted from Siberian forest fires underwent long-range transport over Mongolia and northeast China to the Korean Peninsula, which is located ∼ 3000 km south of the Siberian forest. A notably high aerosol optical depth of ∼ 4 was observed at a wavelength of 500 nm near the source of the Siberian forest fires. Smoke plumes reached 3-5 km in height near the source and fell below 2 km over the Korean Peninsula. Elevated concentrations of levoglucosan were observed (119.7 ± 6.0 ng m −3 ), which were ∼ 4.5 times higher than those observed during non-event periods in July 2014. During the middle of July 2014, a haze episode occurred that was primarily caused by the long-range transport of emission plumes originating from urban and industrial complexes in East China. Sharp increases in SO 2− 4 concentrations (23.1 ± 2.1 µg m −3 ) were observed during this episode. The haze caused by the long-range transport of Siberian forest fire emissions was clearly identified by relatively high organic carbon (OC) / elemental carbon (EC) ratios (7.18 ± 0.2) and OC / SO 2− 4 ratios (1.31 ± 0.07) compared with those of the Chinese haze episode (OC / EC ratio: 2.4 ± 0.4; OC / SO 2− 4 ratio: 0.21 ± 0.05). Remote measurement techniques and chemical analyses of the haze plumes clearly show that the haze episode that occurred during late July 2014 was caused mainly by the long-range transport of smoke plumes emitted from Siberian forest fires.

“…In the NCP, it has been revealed that the vehicular exhaust is the predominant source responsible for the VOC species such as propene, trans/cis-2-butene and trimethylbenzene in the surrounding areas of the observation site (Yuan et al, 2009;Ran et al, 2011;Wu et al, 2016), while the vegetation governs the release of isoprene. It is recommended to take measures for vehicle emission control and land use management (e.g., modifying the amount and types of vegetation) in order to mitigate the pollution of atmospheric peroxides in the NCP Figure 5.…”

Abstract. Measurements of atmospheric peroxides were made during Wangdu Campaign 2014 at Wangdu, a rural site in the North China Plain (NCP) in summer 2014. The predominant peroxides were detected to be hydrogen peroxide (H 2 O 2 ), methyl hydroperoxide (MHP) and peroxyacetic acid (PAA). The observed H 2 O 2 reached up to 11.3 ppbv, which was the highest value compared with previous observations in China at summer time. A box model simulation based on the Master Chemical Mechanism and constrained by the simultaneous observations of physical parameters and chemical species was performed to explore the chemical budget of atmospheric peroxides. Photochemical oxidation of alkenes was found to be the major secondary formation pathway of atmospheric peroxides, while contributions from alkanes and aromatics were of minor importance. The comparison of modeled and measured peroxide concentrations revealed an underestimation during biomass burning events and an overestimation on haze days, which were ascribed to the direct production of peroxides from biomass burning and the heterogeneous uptake of peroxides by aerosols, respectively. The strengths of the primary emissions from biomass burning were on the same order of the known secondary production rates of atmospheric peroxides during the biomass burning events. The heterogeneous process on aerosol particles was suggested to be the predominant sink for atmospheric peroxides. The atmospheric lifetime of peroxides on haze days in summer in the NCP was about 2-3 h, which is in good agreement with the laboratory studies. Further comprehensive investigations are necessary to better understand the impact of biomass burning and heterogeneous uptake on the concentration of peroxides in the atmosphere.
