| 1 | Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants. | Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He | 2021 | National Science Review2021，8，2： | 47 |
| 2 | Impact of meteorological conditions on a nine-day particulate matter pollution event observed in December 2013,Shanghai,China显示文摘A severe particulate matter pollution event occurred in Shanghai from 1 to 9 December 2013.The mean hourly mass concentrations of PM_(2.5) and PM_(10) were 211.9 and 249.0 μg/m^3,respectively.Reanalysis data,in situ,and remote-sensing measurements were used to examine the impacts of meteorological conditions on this event.It was found that the synoptic pattern of weak pressure,the reduced planetary boundary layer height,and the passage of two cold fronts were key factors causing the event.Four stages were identified during this event based on the evolution of its PM_(2.5) levels and weather conditions.The highest concentration of PM2.5(602 μg/m^3) was observed in stage 3.High PM2.5 concentrations were closely associated with a low local ventilation index,with an average of 505m^2/s,as well as with the influx of pollutants from upstream,transported by the cold fronts. | Jianming Xu Fengxia Yan Ying Xie Fengyun Wang Jianbin Wu Qingyan Fu | 2015 | Particuology2015，13，3： | 17 |
| 3 | Ore Genesis of the Kalatongke Cu-Ni Sulfide Deposits, Western China: Constraints from Volatile Chemical and Carbon Isotopic Compositions显示文摘The Kalatongke Cu-Ni sulfide deposits located in the East Junggar terrane, northern Xinjiang, western China are the largest magmatic sulfide deposits in the Central Asian Orogenic Belt (CAOB). The chemical and carbon isotopic compositions of the volatiles trapped in olivine, pyroxene and sulfide mineral separates were analyzed by vacuum stepwise-heating mass spectrometry. The results show that the released volatiles are concentrated at three temperature intervals of 200-400°C, 400-900°C and 900-1200°C. The released volatiles from silicate mineral separates at 400-900°C and 900-1200°C have similar chemical and carbon isotopic compositions, which are mainly composed of H2O (av. ~92 mol%) with minor H2, CO2, H2S and SO2, and they are likely associated with the ore-forming magmatic volatiles. Light δ13CCO2 values (from -20.86‰ to -12.85‰) of pyroxene indicate crustal contamination occurred prior to or synchronous with pyroxene crystallization of mantlederived ore-forming magma. The elevated contents of H2 and H2O in the olivine and pyroxene suggest a deep mantle-originated ore-forming volatile mixed with aqueous volatiles from recycled subducted slab. High contents of CO2 in the ore-forming magma volatiles led to an increase in oxygen fugacity, and thereby reduced the solubility of sulfur in the magma, then triggered sulfur saturation followed by sulfide melt segregation; CO2 contents correlated with Cu contents in the whole rocks suggest that a supercritical state of CO2 in the ore-forming magma system under high temperature and pressure conditions might play a key role in the assemblage of huge Cu and Ni elements. The volatiles released from constituent minerals of intrusion 1# have more CO2 and SO2 oxidized gases, higher CO2/CH4 and SO2/H2S ratios and lighter δ13CCO2 than those of intrusions 2# and 3#. This combination suggests that the higher oxidation state of the volatiles in intrusion 1# than intrusions 2# and 3#, which could be one of key ore-forming factors for large amounts of ores and high contents of Cu and Ni in intrusion 1#. The volatiles released at 200-400°C are dominated by H2O with minor CO2, N2+CO and SO2, with δ13CCO2 values (-25.66‰ to -22.98‰) within the crustal ranges, and are considered to be related to secondary tectonic-hydrothermal activities. | FU Piaoer TANG Qingyan ZHANG Mmgjie ZHANG Zhaowei LI Liwu LI Wenyuan | 2012 | Acta Geologica Sinica(English Edition)2012，86，3： | 11 |
| 4 | Systematic Identification of the Light-quality Responding Anthocyanin Synthesis-related Transcripts in Petunia Petals显示文摘Previous studies have shown that high light intensity can induce anthocyanin synthesis(AS)in petunia plants.To identifywhich kind of light quality plays a role in inducing such metabolic process,and what transcripts participate in controlling it,we carried out whole-transcriptome sequencing and analysis of petunia petals treated with different light-quality conditions.Among the red and white light treatments,a total of 2205 differentially expressed genes and 15,22,and 20 differentially expressed circRNAs,miRNAs,and lncRNAs,were identified respectively.The AS-related genes,including the structural genes CHSj,F3H,F35H,DFR,and ANS,and the regulatory genes AN4,DPL,PHZ and MYBx were found to be downregulated under red light condition compared with their levels under white light condition.Furthermore,the light photoreceptor Cryptochrome 3(CRY3)and a series of light-dependent genes,such as PIF,HY5,andBBXs,were also determined to respond to the light treatments.The anthocyanin contents in early petunia petals under red light were significantly lower than that under white and blue light.The results of qRT-PCR further confirmed the expression pattern of some AS-related and light-response genes in response to different light quality.Yeast two-hybrid results showed that the key elements in the light signal pathway,HY5 can interact with BBX19,BBX24 and BBX25.And PHZ,the important AS regulator can induce anthocyanin synthesis in response to blue light quality fromtransient expression analysis in petunia petals.These findings presented here not only deepen our understanding of how light quality controls anthocyanin synthesis,but also allow us to explore potential target genes for improving pigment production in petunia flower petals. | Zhenzhu Fu Hongquan Shang Hui Jiang Jie Gao Xiaoyu Dong Huijuan Wang Yanmin Li Limin Wang Jing Zhang Qingyan Shu Yacong Chao Menglan Xu Rui Wang Liangsheng Wang Hechen Zhang | 2020 | Horticultural Plant Journal2020，6，6： | 7 |
| 5 | Precursors and potential sources of ground-level ozone in suburban Shanghai显示文摘A high level of ozone(O3)is frequently observed in the suburbs of Shanghai,the reason for this high levei remains unclear.To obtain a detailed insight on the high level of 03 during summer in Shanghai,03 and its precursors were measured at a suburban site in Shanghai from July 1;2016 to July 31,2016.Using the Hybrid Single-Particle Lagrangian Integrated Trajectory,(HYSPLIT)model and concentration weighted trajectories(CW T),we found that Zhejiang province was the main potential source.of 03 in suburban Shanghai.When the sampling site was cotrolled by south-westerm winds exceeding 2 m/s,the O3-rich air masses from upwind regions(such as Zhejiang province)could be transported to the.suburban Shanghai.The propylene-equivalent concentation(PEC)and ozone formation potential(OFP)were,further calculated for each vOC species,and the resuts suggested that propylene,(m+p)-xylene,and.toluene played dominant roles in O3 formation.The Ozone Isopleth Plotting Research(OZIPR)model was used to reveal the impact ofO;precursors on O3 formation,and 4 base-cases were.selected to adjust the model simulaton.An average disparity.of 18.20%was achieved between the simulated and observed 03 concentrations.The 03 isopleth diagram ilustrated that 03 fomatin in July 2016 was in VOC-senstive regime,although the VOCNO,ratio was greater than 20.By intoducing sensitivity(S),a sensitvity analysis was performed for 03 formaton.We found.that 03 formation was senstive to propylene,(m+p)-xylene,e,o-xylene and toluene.The results provide theoretical suppot for 0;plluton treatment in Shanghai. | Kun Zhang Jialuo Xu Qing Huang Lei Zhou Qingyan Fu Yusen Duan Guangli Xiu | 2020 | Frontiers of Environmental Science & Engineering2020，14，6： | 4 |

| 7 | Insights into the formation of secondary organic carbon in the summertime in urban Shanghai显示文摘To investigate formation mechanisms of secondary organic carbon(SOC) in Eastern China,measurements were conducted in an urban site in Shanghai in the summer of 2015. A period of high O_3 concentrations(daily peak > 120 ppb) was observed, during which daily maximum SOC concentrations exceeding 9.0 μg/(C·m^3). Diurnal variations of SOC concentration and SOC/organic carbon(OC) ratio exhibited both daytime and nighttime peaks. The SOC concentrations correlated well with O_x(= O_3+ NO_2) and relative humidity in the daytime and nighttime, respectively, suggesting that secondary organic aerosol formation in Shanghai is driven by both photochemical production and aqueous phase reactions. Single particle mass spectrometry was used to examine the formation pathways of SOC. Along with the daytime increase of SOC, the number fraction of elemental carbon(EC) particles coated with OC quickly increased from 38.1% to 61.9% in the size range of 250–2000 nm, which was likely due to gas-to-particle partitioning of photochemically generated semi-volatile organic compounds onto EC particles. In the nighttime, particles rich in OC components were highly hygroscopic, and number fraction of these particles correlated well with relative humidity and SOC/OC nocturnal peaks. Meanwhile, as an aqueous-phase SOC tracer, particles that contained oxalate-Fe(III) complex also peaked at night. These observations suggested that aqueous-phase processes had an important contribution to the SOC nighttime formation. The influence of aerosol acidity on SOC formation was studied by both bulk and single particle level measurements, suggesting that the aqueous-phase formation of SOC was enhanced by particle acidity. | Ci Zhang Xiaohui Lu Jinghao Zhai Hong Chen Xin Yang Qi Zhang Qianbiao Zhao Qingyan Fu Fei Sha Jing Jin | 2018 | Journal of Environmental Sciences2018，30，10： | 3 |
| 8 | Response of PM_(2.5)-bound elemental species to emission variations and associated health risk assessment during the COVID-19 pandemic in a coastal megacity显示文摘The coronavirus(COVID-19)pandemic is disrupting the world from many aspects.In this study,the impact of emission variations on PM_(2.5)-bound elemental species and health risks associated to inhalation exposure has been analyzed based on real-time measurements at a remote coastal site in Shanghai during the pandemic.Most trace elemental species decreased significantly and displayed almost no diel peaks during the lockdown.After the lockdown,they rebounded rapidly,of which V and Ni even exceeded the levels before the lockdown,suggesting the recovery of both inland and shipping activities.Five sources were identified based on receptor modeling.Coal combustion accounted for more than 70%of the measured elemental concentrations before and during the lockdown.Shipping emissions,fugitive/mineral dust,and waste incineration all showed elevated contributions after the lockdown.The total non-carcinogenic risk(HQ)for the target elements exceeded the risk threshold for both children and adults with chloride as the predominant species contributing to HQ.Whereas,the total carcinogenic risk(TR)for adults was above the acceptable level and much higher than that for children.Waste incineration was the largest contributor to HQ,while manufacture processing and coal combustion were the main sources of TR.Lockdown control measures were beneficial for lowering the carcinogenic risk while unexpectedly increased the non-carcinogenic risk.From the perspective of health effects,priorities of control measures should be given to waste incineration,manufacture processing,and coal combustion.A balanced way should be reached between both lowering the levels of air pollutants and their health risks. | Guochen Wang Kan Huang Qingyan Fu Jia Chen Juntao Huo Qianbiao Zhao Yusen Duan Yanfen Lin Fan Yang Wenjie Zhang Hao Li Jian Xu Xiaofei Qin Na Zhao Congrui Deng | 2022 | Journal of Environmental Sciences2022，34，12： | 2 |

| 10 | Maternal genetic history of ancient Tibetans over the past 4000 years显示文摘The settlement of the Tibetan Plateau epitomizes human adaptation to a high-altitude environment that poses great challenges to human activity.Here,we reconstruct a 4000-year maternal genetic history of Tibetans using 128 ancient mitochondrial genome data from 37 sites in Tibet.The phylogeny of haplotypes M9a1a,M9a1b,D4g2,G2a’c,and D4i show that ancient Tibetans share the most recent common ancestor with ancient Middle and Upper Yellow River populations around the Early and Middle Holocene.In addition,the connections between Tibetans and Northeastern Asians vary over the past 4000 years,with a stronger matrilineal connection between the two during 4000 BPe3000 BP,and a weakened connection after 3000 BP,that are coincident with climate change,followed by a reinforced connection after the Tubo period(1400 BPe1100 BP).Besides,an over 4000-year matrilineal continuity is observed in some of the maternal lineages.We also find the maternal genetic structure of ancient Tibetans is correlated to the geography and interactions between ancient Tibetans and ancient Nepal and Pakistan populations.Overall,the maternal genetic history of Tibetans can be characterized as a long-term matrilineal continuity with frequent internal and external population interactions that are dynamically shaped by geography,climate changes,as well as historical events. | Ganyu Zhang Can Cui Shargan Wangdue Hongliang Lu Honghai Chen Lin Xi Wei He Haibing Yuan Tinley Tsring Zujun Chen Feng Yang Tashi Tsering Shuai Li Norbu Tashi Tsho Yang Yan Tong Xiaohong Wu Linhui Li Yuanhong He Peng Cao Qingyan Dai Feng Liu Xiaotian Feng Tianyi Wang Ruowei Yang Wanjing Ping Ming Zhang Xing Gao Yichen Liu Wenjun Wang Qiaomei Fu | 2023 | Journal of Genetics and Genomics2023，50，10： | 1 |

| 13 | Tauroursodeoxycholic acid(TUDCA)improves intestinal barrier function associated with TGR5-MLCK pathway and the alteration of serum metabolites and gut bacteria in weaned piglets显示文摘Background:Tauroursodeoxycholic acid(TUDCA),a hydrophilic bile acid,is the main medicinal component of bear bile and is commonly used to treat a variety of hepatobiliary diseases.Meanwhile,TUDCA has been shown to modulate the intestinal barrier function and alleviate DSS-induced colitis in mice.However,the effect of TUDCA on the intestinal barrier of weaned piglets remains largely unclear.Methods:The weaned piglets and porcine IPEC-J2 intestinal epithelial cells were used to investigate the effects of TUDCA on intestinal barrier function in weaned piglets and explore the possible underlying mechanisms.In vivo,72 healthy weaned piglets were randomly allocated into 2 groups according to their gender and body weight,and piglets were fed the basal diet with 0(control,CON)and 200 mg/kg TUDCA for 30 d,respectively.Three female and three male piglets reflecting the average bodyweight were slaughtered in each group and samples were collected.In vitro,IPEC-J2 cells were subjected to 100μmol/L TUDCA to explore the possible underlying mechanisms.Results:Our results demonstrated that dietary TUDCA supplementation significantly reduced the diarrhea incidence of weaned piglets,possibly attributing to the TUDCA-enhanced intestinal barrier function and immunity.In addition,TUDCA supplementation altered serum metabolites and the relative abundance of certain gut bacteria,which might contribute to the improved intestinal barrier function.Furthermore,the in-vitro results showed that TUDCA improved the E.coli-induced epithelial barrier impairment of IPEC-J2 cells and increased Takeda G-coupled protein receptor 5(TGR5)protein expression.However,knockdown of TGR5 and inhibition of myosin light chain kinase(MLCK)pathway abolished the TUDCA-improved epithelial barrier impairment in E.coli-treated IPEC-J2 cells,indicating the involvement of TGR5-MLCK in this process.Conclusions:These findings showed that TUDCA improved intestinal barrier function associated with TGR5-MLCK pathway and the alteration of serum metabolites and gut bacteria in weaned piglets,suggesting the potential application of TUDCA in improving gut health in piglet production. | Min Song Fenglin Zhang Yiming Fu Xin Yi Shengchun Feng Zhichang Liu Dun Deng Qiang Yang Miao Yu Canjun Zhu Xiaotong Zhu Lina Wang Ping Gao Gang Shu Xianyong Ma Qingyan Jiang Songbo Wang | 2022 | Journal of Animal Science and Biotechnology2022，13，6： | 1 |
| 14 | Maternal genetic history of southern East Asians over the past 12,000 years显示文摘Southern East Asia,including Guangxi and Fujian provinces in China,is home to diverse ethnic groups,languages,and cultures.Previous studies suggest a high complexity regarding population dynamics and the history of southern East Asians.However,large-scale genetic studies on ancient populations in this region are hindered by limited sample preservation.Here,using highly efficient DNA capture techniques,we obtain 48 complete mitochondrial genomes of individuals from Guangxi and Fujian in China and reconstruct their maternal genetic history over the past 12,000 years.We find a strong connection between southern East Asians dating to~12,000-6000 years ago and present-day Southeast Asians.In addition,stronger genetic affinities to northern East Asians are observed in historical southern East Asians than Neolithic southern East Asians,suggesting increased interactions between northern and southern East Asians over time.Overall,we reveal dynamic connections between ancient southern East Asians and populations located in surrounding regions,as well as a shift in maternal genetic structure within the populations over time. | Yalin Liu Tianyi Wang Xichao Wu Xuechun Fan Wei Wang Guangmao Xie Zhen Li Qingping Yang Peng Cao Ruowei Yang Feng Liu Qingyan Dai Xiaotian Feng Wanjing Ping Bo Miao Yun Wu Yichen Liu Qiaomei Fu | 2021 | Journal of Genetics and Genomics2021，48，10： | 1 |

| 19 | Evidence of aircraft activity impact on local air quality: A study in the context of uncommon airport operation显示文摘Wuhan Tianhe International Airport (WUH) was suspended to contain the spread of COVID-19,while Shanghai Hongqiao International Airport (SHA) saw a tremendousflight reduction.Closure of a major international airport is extremely rare and thus represents a unique opportunity to straightforwardly observe the impact of airport emissions on local air quality.In this study,a series of statistical tools were applied to analyze the variations in air pollutant levels in the vicinity of WUH and SHA.The results of bivariate polar plots show that airport SHA and WUH are a major source of nitrogen oxides.NOx,NO_(2)and NO diminished by 55.8%,44.1%,76.9%,and 40.4%,33.3% and 59.4% during the COVID-19 lockdown compared to those in the same period of 2018 and 2019,under a reduction in aircraft activities by 58.6%and61.4%.The concentration of NO_(2),SO_(2)and PM_(2.5)decreased by 77.3%,8.2%,29.5%,right after the closure of airport WUH on 23 January 2020.The average concentrations of NO,NO_(2)and NOxscatter plots at downwind of SHA after the lockdown were 78.0%,47.9%,57.4%and 62.3%,34.8%,41.8%lower than those during the same period in 2018 and 2019.However,a significant increase in O_(3)levels by 50.0% and 25.9%at WUH and SHA was observed,respectively.These results evidently show decreased nitrogen oxides concentrations in the airport vicinity due to reduced aircraft activities,while amplified O_(3)pollution due to a lower titration by NO under strong reduction in NOxemissions. | Hao Xu Kai Xiao Jun Pan Qingyan Fu Xiaodong Wei Junrui Zhou Yamei Yu Xue Hu Huarui Ren Jinping Cheng Shitao Peng Ningning Hong Yin Ye Ning Su Zehui He Tao Hu | 2023 | Journal of Environmental Sciences2023，，3： | 0 |
| 20 | Elucidate long-term changes of ozone in Shanghai based on an integrated machine learning method显示文摘Surface ozone(O_(3))is influenced by regional background and local photochemical formation under favorable meteorological conditions.Understanding the contribution of these factors to changes in O_(3)is crucial to address the issue of O_(3)pollution.In this study,we propose a novel integrated method that combines random forest,principal component analysis,and Shapley additive explanations to distinguish observed O_(3)into meteorologically affected ozone(O_(3_MET)),chemically formed from local emissions(O_(3_LC)),and regional background ozone(O_(3_RBG)).Applied to three typical stations in Shanghai during the warm season from 2013 to 2021,the results indicate that O_(3_RBG)in Shanghai was 48.8±0.3 ppb,accounting for 79.6%–89.4%at different sites,with an overall declining trend of 0.018 ppb/yr.O_(3_LC)at urban and regional sites ranged from 5.9–9.0 ppb and 8.9–14.6 ppb,respectively,which were significantly higher than the contributions of 2.5–7.4 ppb at an upwind background site.O_(3_MET)can be categorized into those affecting O_(3)photochemical generation and those changing O_(3)dispersion conditions,with absolute contributions to O_(3)ranging from 13.4–19.0 ppb and 13.1–13.7 ppb,respectively.We found that the O_(3)rebound in 2017,compared to 2013,was primarily influenced by unfavorable O_(3)dispersion conditions and unbalanced emission reductions;while the O_(3)decline in 2021,compared to 2017,was primarily influenced by overall favorable meteorological conditions and further emissions reduction.These findings highlight the challenge of understanding O_(3)change due to meteorology and regional background,emphasizing the need for systematic interpretation of the different components of O_(3). | Jin Xue Fangting Wang Kun Zhang Hehe Zhai Dan Jin Yusen Duan Elly Yaluk Yangjun Wang Ling Huang Yuewu Li Thomas Lei Qingyan Fu Joshua S.Fu Li Li | 2023 | Frontiers of Environmental Science & Engineering2023，17，11： | 0 |
