Abstract :

A variety of methods based on air quality models, including tracer methods, the brute-force method (BFM), decoupled direct method (DDM), high-order decoupled direct method (HDDM), response surface models (RSMs) and so on forth, have been widely used to study the transport of air pollutants. These methods have good applicability for the transport of air pollutants with simple formation mechanisms. However, differences in research conclusions on secondary pollutants with obvious nonlinear characteristics have been reported. For example, the tracer method is suitable for the study of simplified scenarios, while HDDM and RSMs are more suitable for the study for nonlinear pollutants. Multiple observation techniques, including conventional air pollutant observation, lidar observation, air sounding balloons, vehicle-mounted and ship-borne technology, aerial surveys, and remote sensing observations, have been utilized to investigate air pollutant transport characteristics with time resolution as high as 1 sec. In addition, based on a multi-regional input-output model combined with emission inventories, the transfer of air pollutant emissions can be evaluated and applied to study the air pollutant transport characteristics. Observational technologies have advantages in temporal resolution and accuracy, while modeling technologies are more flexible in spatial resolution and research plan setting. In order to accurately quantify the transport characteristics of pollutants, it is necessary to develop a research method for interactive verification of observation and simulation. Quantitative evaluation of the transport of air pollutants from different angles can provide a scientific basis for regional joint prevention and control.

Abstract :

利用核壳型的CdSe@CdS量子点作为发光物质,并用壳聚糖(CS)、类石墨烯氮化碳(gC_3N_4)与CdSe@CdS量子点合成了CdSe@CdS/CS/gC_3N_4复合物,将该复合物修饰至玻碳电极(GCE)表面,将适配体(Apt)的互补DNA链(cDNA)通过化学反应连接到量子点上,Apt与cDNA发生杂交反应而被修饰至电极表面。将辣根过氧化物酶(HRP)固定到该修饰电极表面,构建了检测卡那霉素(Kana)的电化学发光(ECL)适配体传感器。通过生物催化沉淀(BCP)方法实现Kana的检测,溶液中无Kana时,在H_2O_2的存在下,修饰在电极上的HRP可以催化氧化4-氯-1-萘酚(4-CN),在电极表面产生不导电的苯并-4-氯己二烯酮沉淀,导致电化学发光信号明显降低。溶液中存在Kana时,Kana会与Apt特异性结合,部分dsDNA解旋,导致部分HRP从电极表面脱落,BCP反应减弱,导致ECL信号增强,实现目标物质的特异性检测。计算适配体传感器在Kana溶液中的ECL强度(I)与传感器在空白溶液中的ECL强度(I_0)的差值ΔI (I-I_0),并以此作为响应信号。结果显示,ΔI与Kana浓度的对数值在1.0×10~(-8)~1.0×10~(-4) g/L范围呈良好的线性关系,检出限为5 ng/L。该传感器在实际样品测定中具有较好的应用前景。

Abstract :

Great changes occurred in the physical and chemical properties of the atmosphere in the North China Plain (NCP) in summer caused by PM2.5 dropping from 58 mu g/m(3) in 2015 to 36.0 mu g/m(3) in 2019. In this study, we first applied the WRF-Chem model to quantify the impact of PM2.5 reduction on shortwave radiation reaching the ground (SWDOWN), planetary boundary layer height (PBLH), and the surface concentration of air pollutants (represented by CO). Simulation results obtained an increase of 15.0% in daytime SWDOWN and 9.9% in daytime PBLH, and a decrease of -5.0% in daytime CO concentration. These changes were induced by the varied PM2.5 levels. Moreover, the variation in SWDOWN further led to a rise in the NO2 photolysis rate (JNO(2)) over this region, by 1.82 x 10(-4)similar to 1.91 x 10(-4) s(-1) per year. Afterwards, we employed MCM chemical box model to explore how the JNO(2) increase and the precursor decrease (CO, VOCs, and NOx) influenced O-3 and HO2 radicals. The results revealed that the photolysis rate U) increase would individually cause a change on daytime surface O-3, OH, and HO2 radicals by +9.0%, +18.9%, and +23.7%; the corresponding change induced by the precursor decrease was -2.5%, +1.9%, and -2.3%. At the same time, the integrated impacts of the change in J and precursors cause an increase of +6.3%, +21.1%, and +20.9% for daytime surface O-3, OH, and HO2. Generally, the atmospheric oxidation capacity significantly enhanced during summer in NCP due to the PM2.5 dropping in recent years. This research can help understand atmosphere changes caused by PM2.5 reduction comprehensively.

Abstract :

In this paper, a regional emissions inventory of anthropogenic VOCs was established based on the traditional emissions factor method for the Beijing-Tianjin-Hebei (BTH) region, followed by a multidimensional calibration study based on regional satellite remote sensing information for formaldehyde and typical urban ground VOCs. Inventory calculations showed that the VOCs emissions in BTH in 2013, 2015, and 2017 were 2026700, 2073400, and 1934200 tons, respectively, comprising alkanes (29.83% to 30.72%), unsaturated hydrocarbons (16.54% to 17.68%), aromatic hydrocarbons (27.14% to 27.51%), aldehydes (8.75% to 9.52%), ketones (8.13% to 9.04%), and aldehydes and ketones lipids (5.13% to 6.60%). During 2013-2017, the emission of VOCs in Zhangjiakou, Qinhuangdao, and Hengshui increased slightly (1.10% to 1.66% per year); emissions in Xingtai and Handan decreased slightly (-1.46% to -1.12% per year); and emissions in Chengde, Tangshan, Baoding, and Cangzhou were stable. There trends were consistent with the inter-annual trend of satellite-derived HCHO column concentrations. However, in Beijing, Tianjin, Langfang, and Shijiazhuang, annual variations in VOCs emissions (-6.51%, -3.30%, 2.16%, and 0.11% per year) and HCHO column concentrations (-1.17%, 7.19%, -0.24%, and 6.68% per year) were observed, respectively. In the regional VOCs inventory, a good linear correlation (R>0.5) was achieved between the grid emissions of VOCs and HCHO column concentrations in urban areas, while the correlation was only 0.33 in suburban areas. This is mainly due to the important influence of secondary conversion of VOCs originating from natural sources to HCHO in suburban areas. In addition, ground-level VOCs concentrations were observed in the urban areas of Beijing and Handan, where the emission ratios (ERs) of VOCs and CO were regressed. The ERs of most hydrocarbons were in good agreement with the regressed ERs, but the ERs of ethane were significantly lower (-156% to -73%) and the ERs of aromatic hydrocarbons above C8 were relatively high (54% to 74%). In general, the regional anthropogenic VOCs emissions inventory established in this paper offers high accuracy and reliability.

Abstract :

Ozone pollution in Handan has become severe in recent years and in the summer of 2018, the average maximum daily 8-hour average ozone concentration in Handan was 175 μg·m-3 with a maximum of 257 μg·m-3. Ozone concentrations exceeded the National Air Quality Grade Ⅱ Standard in 59% of cases. In this study, the H2O2/HNO3 indicator was applied to analyze summertime ozone sensitivity in Handan using the WRF-CMAQ modeling system. The results showed that H2O2/HNO3 was more appropriate than other ozone indicators, both theoretically and based on simulation outputs. The good simulation effect of CMAQ on H2O2 and HNO3 was attributed to fine emission inventory and grid resolution. The H2O2/HNO3 simulation results showed that the relative importance of a VOCs-limited regime decreased month by month; a VOCs-NO x -mixed-limited regime was dominant in June; and a NO x -limited regime was more dominant in July and August than in June. The remarkable spatial difference in VOCs and NO x emission ratios among the counties of Handan led to differences in ozone sensitivity. The VOCs-limited regime was concentrated in counties where VOCs/NO x emission ratios were lower than 1.7. Southern counties had a NO x -limited regime, where VOCs/NO x emission ratios were higher than 6.9. Counties with VOCs/NO x emission ratios varying from 1.7 to 6.9 were more susceptible to both VOCs and NO x . According to these results, the transition range of HCHO/NO2, O3/HNO3, and O3/NO x ratios were adjusted to 0.35-0.6, 20-35, and 10-25 respectively. Adjusting the transition range of H2O2/(O3+NO2) was not effective, indicating that this indicator may not be applicable to Handan.

Improving source inversion performance of airborne pollutant emissions by modifying atmospheric dispersion scheme through sensitivity analysis combined with optimization model. PubMed

Abstract :

Estimating accurately airborne pollutant emissions source information (source strength and location) is important for achieving effective air pollution management or adequate emergency responses to accidents. Inversion method is one of the useful tools to identify the source parameters. The atmospheric dispersion scheme has been proven to be the key to determining the source inversion performance by influencing the accuracy of the dispersion models. Modifying the atmospheric dispersion scheme is an important potential method to improve the inversion performance, but this has not been studied previously. To fill this gap, a novel approach for parameter sensitivity analysis combined with an optimization method was proposed to improve the source inversion performance by optimizing empirical scheme. The dispersion coefficients σy and σz of the typical BRIGGS scheme under different atmospheric dispersion conditions were optimized and used for air pollutant dispersion and source inversion. The results showed that the prediction performance of the air pollutant concentrations was greatly improved with statistical indices |FB| and NMSE decreased by 0.22 and 2.07, respectively; FAC2 and R increased by 0.10, and 0.08, respectively. For source inversion, the results of the significance analysis suggested that the accuracy in the source strength and location parameter (x0) were both significantly improved by ∼271% (relative deviation reduced from 60.0% to 16.2%) and ∼121% (absolute deviation reduced from 27.6 to 12.5 m). The improvement of source strength inversion accuracy was more significant under unstable atmospheric conditions (stability class A, B, and C); the mean absolute relative deviation was reduced by 97.5%. These results can help to obtain more accurate source information and to provide reliable reference for air pollution managements or emergency response to accidents. This study provides a novel and versatile approach to improve estimation performance of pollutant emission sources and enhances our understanding of source inversion.

Key factors influencing the formation of sulfate aerosol on the surface of mineral aerosols: Insights from laboratory simulations and ACSM measurements SCIE

Abstract&Keyword Cite

Abstract :

A significant technique of combining simulation experiments with a long-term real-time field measurement was first deployed to explore impacts of various environmental factors on formations of sulfate aerosol on the surface of mineral aerosols as MgO in the different reaction systems, and synergistic impacts of these environmental factors on the formation of sulfate aerosols in the different seasonal systems, especially in haze days. Meanwhile, a new correction technique was developed to estimate the effective reaction area and initial uptake coefficient of SO2 on the MgO aerosol surfaces. The significant results showed that the reactions of SO2 on the MgO aerosol surfaces in the system of SO2-MgO-dark could produce a small amount of sulfate and a large amount of sulfite and bisulfite, while in the systems of SO2-MgO-h? and SO2-MgO-O3 produce a large amount of sulfate and a small amount of sulfite and bisulfite. The impacts of temperature T and relative humidity RH on the sulfate formation on MgO aerosol surfaces showed a single-peak mode under the UV light condition, respectively. The sensitivities of these environmental factors to the sulfate aerosol formation were found to follow the order of RH > UV >T > O3 > SO2. The revised initial uptake coefficient ?0.REV of SO2 on the MgO aerosols was always between ?0.BET and ?0.GEO, and much closer to actual value. The heterogeneous reaction mechanisms of SO2 on the MgO aerosol surfaces in the different reaction systems were obviously different. In the presence of water, light irradiation and O3 exerted crucially significant roles in promoting sulfate heterogeneous formation. The various environmental factors in the different seasonal systems, especially in haze days, showed different synergistic effects on sulfate aerosol formations. The sulfate aerosol formations in haze days were mostly impacted by RH, T, O3, and SO2 in spring, RH in summer, RH, T, and SO2 in autumn, and RH and SO2 in winter. The study will provide significant scientific bases for understanding and controlling haze pollution formation.

Abstract :

The air quality of Handan, a typical industrial city in China, has been significantly improved through atmospheric pollution control, except for ozone (O-3) pollution. We found that, in summer, emissions of anthropogenic volatile organic compounds (VOCs) and NOx decreased yearly in Handan, but the O-3 concentration significantly declined yearly during 2013-2015, whereas it experienced worsening O-3 pollution after 2015. Therefore, we used the Weather Research and Forecasting Community Multiscale Air Quality (WRF-CMAQ) modeling system to simulate the influence of the meteorological conditions and emission changes in Handan during the typical period (June) of O-3 pollution in 2013-2018. For benchmarked June 2013, the results showed that the reduction of the O-3 concentration in June of 2014-2016 was mainly caused by emission reduction, while in June of 2017-2018, the combined effect of changes in emissions and meteorological conditions led to aggravated O-3 pollution. Sensitivity analysis indicated that combined VOCs and NOx emission controls would effectively reduce incremental O-3 formation when the abatement ratio of VOCs/NOx should be no less than 0.84, and we found that VOCs reduction would continusouly bring about O-3 decreases under various NOx reductions, but its positive sensitivity to O-3 would become smaller with NOx reduction. However, the positive influence of NOx reduction on O-3 would happen until NOx reduction exceeding 45-60%. The findings will be helpful in formulating emission control strategies for coping with O-3 pollution in an industrial city.
