| 1 | Pollution characteristics of organic and elemental carbon in PM_(2.5) in Xiamen,China显示文摘Xiamen,located on the southeastern coastal line of China,is undergoing rapid urbanization and industrialization,so its air quality has a trend of degradation.However,studies on level,temporal and spatial changes of fine particles (PM 2.5) and their carbonaceous fractions are scarce.In this article,abundance,sources,seasonal and spatial variations,distribution of organic carbon (OC) and elemental carbon (EC) in PM 2.5,were studied at suburban,urban and industrial sites in Xiamen during four season-representative months in 2009-2010.PM 2.5 samples were collected with middle volume sampler and were analyzed for OC and EC with thermal optical transmittance (TOT) method.Results showed that the annual average PM 2.5 concentrations were 63.88-74.80 μg/m 3 at three sites.While OC and EC concentrations were in the range of 15.81-19.73 μg/m 3 and 2.74-3.49 μg/m 3,respectively,and clearly presented the summerminima and winter maxima in this study.The carbonaceous aerosol accounted for 42.8%-47.3% of the mass of PM 2.5.The annual average of secondary organic carbon (SOC) concentrations in Xiamen were 9.23-11.36 μg/m 3,accounting for approximately 56% of OC.Strong correlations between OC and EC was found in spring (R 2=0.50) and autumn (R 2=0.73),suggesting that there were similar emission and transport processes for carbonaceous aerosols in these two seasons,while weak correlations were found in summer (R 2=0.33) and winter (R 2=0.41).The OC/EC ratios in PM 2.5 varied from 2.1 to 8.7 with an annual average of 5.7,indicating that vehicle exhaust,coal smoke and biomass burning were main source apportionments of carbonaceous fractions in Xiamen. | Fuwang Zhang Jinping Zhao Jinsheng Chen Ya Xu Lingling Xu | 2011 | Journal of Environmental Sciences2011，23，8： | 27 |
| 2 | Chemical compositions of PM_(2.5) aerosol during haze periods in the mountainous city of Yong'an, China显示文摘Haze phenomena were found to have an increasing tendency in recent years in Yong'an, a mountainous industrial city located in the center part of Fujian Province, China. Atmospheric fine particles (PM2.5) in the urban area during haze periods in three seasons (spring, autumn and winter) from 2007 to 2008 were collected, and the mass concentrations and chemical compositions (seventeen elements, water soluble inorganic ions (WSIIs) and carbonaceous species) of PM2.5 were determined. PM2.5 mass concentrations did not show a distinct difference among the three seasons. The carbonaceous species organic carbon (OC) and elemental carbon (EC) constituted up to 19.2%-30.4% of the PM2.5 mass during sampling periods, while WSIIs made up 25.3%-52.5% of the PM2.5 mass. The major ions in PM2.5 were SO42-, NO3- and NH4+, while the major elements were Si, K, Pb, Zn, Ca and Al. The experimental results (from data based on three haze periods with a 10-day sampling length for each period) showed that the crustal element species was the most abundant component of PM2.5 in spring, and the secondary ions species (SO42-, NO3-, NH4+, etc.) was the most abundant component in PM2.5 in autumn and winter. This indicated that dust was the primary pollution source for PM2.5 in spring and combustion and traffic emissions could be the main pollution sources for PM2.5 in autumn and winter. Generally, coal combustion and traffic emissions were considered to be the most prominent pollution sources for this city on haze days. | LiqianYin Zhenchuan Niu Xiaoqiu Chen Jinsheng Chen Lingling Xu Fuwang Zhang | 2012 | Journal of Environmental Sciences2012，24，7： | 19 |
| 3 | Chemical characteristics of PM_(2.5) during haze episodes in the urban of Fuzhou,China显示文摘Atmospheric fine particles(PM_(2.5)) were collected in this study with middle volume samplers in Fuzhou,China,during both normal days and haze days in summer(September 2007) and winter(January 2008).The concentrations,distributions,and sources of polycyclic aromatic hydrocarbons(PAHs),organic carbon(OC),elemental carbon(EC),and water soluble inorganic ions(WSIIs) were determinated.The results showed that the concentrations of PM2.5,PAHs,OC,EC,and WSIIs were in the orders of haze > normal and winter > summer.The dominant PAHs of PM2.5 in Fuzhou were Fluo,Pyr,Chr,BbF,BkF,BaP,BghiP,and IcdP,which represented about 80.0%of the total PAHs during different sampling periods.The BaPeq concentrations of ∑PAHs were 0.78,0.99,1.22,and 2.43 ng/m3 in summer normal,summer haze,winter normal,and winter haze,respectively.Secondary pollutants(SO_4^(2-),NO_3^-,NH_4^+.and OC) were the major chemical compositions of PM2.5,accounting for 69.0%,55.1%,63.4%,and 64.9%of PM2.5 mass in summer normal,summer haze,winter normal,and winter haze,respectively.Correspondingly,secondary organic carbon(SOC) in Fuzhou accounted for 20.1%,48.6%,24.5%,and 50.5%of OC.The average values of nitrogen oxidation ratio(NOR) and sulfur oxidation ratio(SOR) were higher in haze days(0.08 and 0.27) than in normal days(0.05 and 0.22).Higher OC/EC ratios were also found in haze days(5.0) than in normal days(3.3).Correlation analysis demonstrated that visibility had positive correlations with wind speed,and negative correlations with relative humidity and major air pollutants.Overall,the enrichments of PM_(2.5),OC,EC,SO_4^(2-),and NO_3^- promoted haze formation.Furthermore,the diagnostic ratios of IcdP/(IcdP + BghiP),IcdP/BghiP,OC/EC,and NO_3^-/SO_4^(2-) indicated that vehicle exhaust and coal consumption were the main sources of pollutants in Fuzhou. | Fuwang Zhang Lingling Xu Jinsheng Chen Xiaoqiu Chen Zhenchuan Niu Tong Lei Chunming Li Jinping Zhao | 2013 | Particuology2013，11，3： | 19 |
| 4 | Comparison of Persulfate Activation and Fenton Reaction in Remediating an Organophosphorus Pesticides-Polluted Soil显示文摘Organophosphorus pesticides(OPs) are one of the most regular pollutants and frequently detected in the contaminated sites,so developing an efficient method for the treatment of OPs is highly required. The aim of the present study was to compare the effectiveness of persulfate(PS) activation and Fenton reaction in remediating the soil polluted with OPs. The polluted soil used in this study was sampled from an abandoned insecticide factory in Nantong, Jiangsu Province of China, mainly containing chloropyrifos(CP) and 4-bromo-2-chlorophenol(BCP, the raw material of profenofos) with total concentration of about 30 000 mg kg^(-1). The results showed that both BCP and CP were efficiently degraded by base activation of PS, and increasing the ratio of Na OH/PS enhanced CP degradation, but slightly decreased BCP degradation. The greatest degradation rates for CP and BCP were 92% and 97%, respectively,with 7.0 mol L^(-1) Na OH and 0.21 mol L^(-1) PS and a soil-to-liquid ratio of 1:1. Furthermore, ferrous iron activation of PS also degraded BCP efficiently, but only 60% of CP was degraded under the same reaction conditions. These results indicated that base activation of PS was more feasible than Fe^(2+) activation and Fenton reaction in remediating the soil polluted with OPs. The high degradation rate for CP may be linked to the initial hydrolyzation of CP by base to 3,5,6-trichloro-2-pyridinol, which can be further rapidly degraded by free radicals generated from base activation of PS. | ZHU Changyin ZHU Fengxiao WANG Fuwang GAO Juan FAN Guangping ZHOU Dongmei FANG Guodong | 2017 | Pedosphere2017，27，3： | 11 |
| 5 | Characterization of polycyclic aromatic hydrocarbons and gas/particle partitioning in a coastal city, Xiamen, Southeast China显示文摘An intensive sampling program had been undertaken in autumn (October, 2008) and winter (December, 2008 and January, 2009) at urban (Xiamen University and Xianyue residential area), suburban (Institute of Urban Environment), industrial area (Lulian Hotel) and background (Tingxi Reservoir) in Xiamen, Fujian Province, to characterize the atmospheric concentration and gas-particle phase partitioning of PAHs. The average concentration of total PAHs in winter was almost 1.7 times higher than those in autumn. The log scale plot of Kp versus sub-cooled liquid vapor pressure (P0L) for all the data of autumn and winter season samples gave significantly different slopes. The slope for the winter samples (-0.72) was steeper than that for the autumn samples (-0.58). The partitioning results indicated that slope values varied depending on characteristics of specific site, source region and meteorological conditions which play important roles in the partitioning of PAHs. In addition, local emission sources had a stronger effect on partitioning results than long-transported polluted plume. The sources of PAHs in five sampling sites in Xiamen also have been discussed initially. Diagnostic ratios showed that the primary source of PAHs in urban, suburban and industrial area was from vehicle exhausts. While emission from petrochemical factory and power plant was another main contributor to industrial area. | Jinping Zhao Fuwang Zhang Jinsheng Chen Ya Xu | 2010 | Journal of Environmental Sciences2010，22，7： | 9 |
| 6 | Temporal-spatial distribution and ore-forming material source of gold,copper and silver polymetallic ore deposits in the Fuping mantle structure zone显示文摘This study was conducted following research on metallogenesis in the Zhangjiajie-Xuanhua and East Hebei mantle branch structure zones. The Fuping mantle branch structure zone is one where Au, Cu and Ag poly-metallic ore resources are concentrated in North Hebei. However, there has existed a long-standing controversy on the temporal-spatial distribution of ore resources and their ore-forming material sources. In terms of age dating and the comprehensive analysis of S, Pb, O, C and Si isotopes, it is considered that the temporal-spatial distribution of ore resources in this mantle branch structure zone is obviously controlled by the Fuping mantle branch structure. In space there is developed such a metallogenic pattern as to be Ag, Pb and Zn polymetallic ore deposits with gold appearing inside and copper appearing outside. Metallogenesis is dated mainly at Yanshanian, the ore-forming materials were derived predominantly from the deep interior of the Earth, and ore-forming fluids were derived largely from Yanshanian magmatism. | WANG Baode NIU Shuyin SUN Aiqun LIU Yaming XIE Yan JIANG Xiaoping ZHAO Yongli GAO Yincang ZHAO Fuwang | 2010 | Chinese Journal Of Geochemistry2010，29，3： | 6 |
| 7 | Co-seismic changes of well water level and volume strain meter in capital area and its vicinity,due to the Nov.14,2001 Ms8.1 Kunlun Mountain earthquake,China显示文摘The Kunlunshan Mountain Ms8.1 earthquake, occurred in Nov.14, 2001, is the first event with magnitude more than 8 in the China earthquake monitoring history, specifically at the beginning of digital techniques in precursor monitoring networks. Any investigation of recorded data on this earthquake is very important for testing the operation of the digital monitoring networks and understanding the preparation, occurrence, and adjustment of stress/strain of strong continental earthquakes. In this paper we investigated the coseismic response changes of well water level of groundwater and volume strain meter of bore hole in digital earthquake monitoring network of Capital area and its vicinity, due to the Nov.14, 2001 Ms8.1 Kunlun Mountain earthquake. The responding time, shapes or manners, amplitudes, and lasting time of well water level and strain-meters to seismic wave are studied in comparison. Then we discussed the possibility that the response changes of groundwater to strong distant earthquakes can be understood as one kind of observing evidence of stress/strain changes induced by distant earthquake. | Huang Fuqiong Chen Yong Ji Ping Ren Kexin Gao Fuwang Zhang Lingkong | 2015 | Geodesy and Geodynamics2015，6，6： | 3 |
| 8 | Analysis of molecular variation in porcine reproductive and respiratory syndrome virus in China between 2007 and 2012显示文摘In the present study, 89 porcine reproductive and respiratory syndrome virus(PRRSV) isolates in China during 2007 to 2012 were randomly selected from the GenBank genetic sequence database. Evolutionary characteristics of these isolates were analyzed based on the sequences of non-struc-tural protein 2(Nsp2) and glycoprotein 5(GP5). The genetic variations of the isolates were also compared with six representative strains. The results showed that a high degree of genetic diversity exists among the PRRSV population in China. Highly pathogenic PRRSV isolates, with a discon-tinuous deletion of a 30 amino acid residue in the Nsp2 region, remained the most dominant virus throughout 2007–2012 in China. Owing to the extensive use of representative vaccine strains, natu-ral recombination events occurred between strains. Three isolates – HH08, DY, and YN-2011 – were more closely related to vaccine strains than the other isolates. Both YN-2011 and DY were the evolu-tionary products of recombination events between strains SP and CH-1R. The results of the present study provide useful information for the epidemiology of PRRSV as well as for vaccine development. | Yuhang Cao Hongsheng Ouyang Mingjun Zhang Fuwang Chen Xin Yang Daxing Pang Linzhu Ren | 2014 | Virologica Sinica2014，29，3： | 2 |

| 16 | Methods for bearings-only underwater target motion analysis显示文摘The problem of estimation of underwater target motion parameters via bearings only is the most of ten encountered and most difficult to solve in the underwater target motion analysis.As the bearings-only target motion analysis is a nonlinear and multiextremal global optimization problem, so most classical estimation methods often lead the solution to convergence to one of the local extremes other than the global extreme, especially, when the noise of target bearing observation is added. In this paper we propose to use the Generalized Least Square method on the rough estimation of target motion parameters, and then use the Sequential Uniform Design method to gain a more precise estimation on the bases of rough estimation.The latter ensures that the result convergences to the global extreme. The algorithm based on the above two methods is profitable for the bearings-only target motion analysis even under conditions of large bearing observation error. | PAN Zhijian and YAN Fuwang (Marine Research Center, P.B. 1303-15 Beijing 100073)LIU Mengan and WANG Guangen (Applied Acoustics Institute, P.B. 1 Fuyang 311400) | 1997 | Chinese Journal of Acoustics1997，16，3： | 1 |
| 17 | Optimization of the Extraction Process of Polysaccharides from Tegillarca granosa by Response Surface Methodology显示文摘[Objective] The aim was to use response surface methodology to determine optimum conditions for extraction of polysaccharides from Tegillarca granosa. [Method] Response surface methodology with three-factors and three-levels was carried out for optimizing the extraction process of polysaccharides from Tegillarca granosa. A central composite design including independent variables, such as extraction temperature (A), extraction time (B), and ethanol concentration (C) was obtained through Box-Benhnken central combination design. Selected response which evaluates the extraction process was polysaccharide yield. [Result] The independent variable with the largest effect on response was ethanol concentration (C). The optimum extraction conditions were found to be extraction temperature 69.6 ℃, extraction time 6.2 h, and ethanol concentration of 78% (V/V), respectively. Under these conditions, the extraction efficiency of polysaccharide can increase to 1.635%. [Conclusion] Study on the extraction of polysaccharides from Tegillarca granosa could provide certain theoretical direction for extracting polysaccharides from Tegillarca granosa on a large scale. | KONG Fuwang JIANG Yuxing ZHAN Xiaodong TANG Xiaoniu | 2012 | Chinese Food Science2012，1，4： | 1 |
