| 2 | Characteristics of the pollutant emissions in a tunnel of Shanghai on a weekday显示文摘Tunnel displays a typical semi-closed environment, and multitudes of the pollutants tend to accumulate. The samples of gaseous pollutants and particulate matter(PM) were collected from the Xiangyin tunnel at Shanghai to investigate the characteristics of the pollutant emissions. The results indicated that both gaseous pollutants and PM exhibited much higher concentrations during the rush hours in the morning and at night due to vehicle emission. Two peaks of the PM concentration were observed in the scope of 0.7‐1.1 and 3.3–4.7 μm, accounting for 14.6% and 20.3% of the total concentrations, respectively.Organic matter(OM), EC, and many water-soluble ions were markedly higher at the rush hours in the morning than those at night, implicating comprehensive effects of vehicle types and traffic volume. The particle number concentrations exhibited two peaks at Aitken mode(25 nm and 100 nm) and accumulation mode(600 nm), while the particle volume concentration displayed high values at the accumulation mode(100–500 nm) and coarse mode(2.5–4.0 μm). The peak around 100 nm was detected in the morning rush hours, but it diminished with the decrease of the traffic volume. Individual-particle analysis revealed that main particles in the tunnel were Fe-rich particles, K-rich particles, mineral particles,Ca–S rich particles and Al–Si particles. The particles collected at the rush hours displayed marked different morphologies, element concentrations and particle sizes compared to the ones collected at the non-rush period. The data presented herein could shed a light on the feature of vehicle emissions. | Rui Li Ya Meng Hongbo Fu Liwu Zhang Xingnan Ye Jianmin Chen | 2018 | Journal of Environmental Sciences2018，30，9： | 4 |

| 8 | Hygroscopicity and optical properties of alkylaminium sulfates显示文摘The hygroscopicity and optical properties of alkylaminium sulfates(AASs) were investigated using a hygroscopicity tandem diferential mobility analyzer coupled to a cavity ring-down spectrometer and a nephelometer. AAS particles do not exhibit a deliquescence phenomenon and show a monotonic increase in diameter as the relative humidity(RH) ascends. Hygroscopic growth factors(GFs) for 40, 100 and 150 nm alkylaminium sulfate particles do not show an apparent Kelvin efect when RH is less than 45%, whereas GFs of the salt aerosols increase with initial particle size when RH is higher than 45%. Calculation using the Zdanovskii-Stokes-Robinson mixing rule suggests that hygroscopic growth of triethylaminium sulfate-ammonium sulfate mixtures is non-deliquescent, occurring at very low RH, implying that the displacement of ammonia by amine will significantly enhance the hygroscopicity of(NH4)2SO4aerosols. In addition, light extinction of AAS particles is a combined efect of both scattering and absorption under dry conditions, but is dominated by scattering under wet conditions. | Dawei Hu Chunlin Li Hui Chen Jianmin Chen Xingnan Ye Ling Li Xin Yang Xinming Wang Abdelwahid Mellouki Zhongyang Hu | 2014 | Journal of Environmental Sciences2014，26，1： | 0 |
| 9 | Diverse bacterial populations of PM_(2.5) in urban and suburb Shanghai,China显示文摘Airborne bacteria play key roles in terrestrial and marine ecosystems and human health,yet our understanding of bacterial communities and their response to the environmental variables lags significantly behind that of other components of PM_(2.5).Here,atmospheric fine particles obtained from urban and suburb Shanghai were analyzed by using the qPCR and Illumina Miseq sequencing.The bacteria with an average concentration of 2.12× 10^(3 )cells/m^(3),were dominated by Sphingomonas,Curvibacter,Acinetobacter,Bradyrhizobium,Methylobacterium,Halomonas,Aliihoeflea,and Phyllobacterium,which were related to the nitrogen,carbon,sulfur cycling and human health risk.Our results provide a global survey of bacterial community across urban,suburb,and high-altitude sites.In Shanghai(China),urban PM2.5 harbour more diverse and dynamic bacterial populations than that in the suburb.The structural equation model explained about 27%,41%,and 20%^78%of the variance found in bacteria diversity,concentration,and discrepant genera among urban and suburb sites.This work furthered the knowledge of diverse bacteria in a coastal Megacity in the Yangtze river delta and emphasized the potential impact of environmental variables on bacterial community structure. | Caihong Xu Jianmin Chen Zhikai Wang Hui Chen Hao Feng Lujun Wang Yuning Xie Zhenzhen Wang Xingnan Ye Haidong Kan Zhuohui Zhao Abdelwahid Mellouki | 2021 | Frontiers of Environmental Science & Engineering2021，15，3： | 0 |
