| 1 | Chemical characterization of size-resolved aerosols in four seasons and hazy days in the megacity Beijing of China显示文摘Size-resolved aerosol samples were collected by MOUDI in four seasons in 2007 in Beijing. The PM10 and PM1.8mass concentrations were 166.0 ± 120.5 and 91.6 ± 69.7 μg/m^3, respectively,throughout the measurement, with seasonal variation: nearly two times higher in autumn than in summer and spring. Serious fine particle pollution occurred in winter with the PM1.8/PM10 ratio of 0.63, which was higher than other seasons. The size distribution of PM showed obvious seasonal and diurnal variation, with a smaller fine mode peak in spring and in the daytime. OM(organic matter = 1.6 × OC(organic carbon)) and SIA(secondary inorganic aerosol) were major components of fine particles, while OM, SIA and Ca_2+were major components in coarse particles. Moreover, secondary components, mainly SOA(secondary organic aerosol) and SIA,accounted for 46%–96% of each size bin in fine particles, which meant that secondary pollution existed all year. Sulfates and nitrates, primarily in the form of(NH_4)_2SO_4, NH_4NO_3, Ca SO_4, Na_2SO_4 and K_2SO_4, calculated by the model ISORROPIA II, were major components of the solid phase in fine particles. The PM concentration and size distribution were similar in the four seasons on non-haze days, while large differences occurred on haze days, which indicated seasonal variation of PM concentration and size distribution were dominated by haze days. The SIA concentrations and fractions of nearly all size bins were higher on haze days than on non-haze days, which was attributed to heterogeneous aqueous reactions on haze days in the four seasons. | Kang Sun Xingang Liu Jianwei Gu Yunpeng Li Yu Qu Junling An Jingli Wang Yuanhang Zhang Min Hu Fang Zhang | 2015 | Journal of Environmental Sciences2015，27，6： | 19 |
| 2 | A fishy odor episode in a north China reservoir: Occurrence, origin, and possible odor causing compounds显示文摘A significant outbreak of fishy odor occurred in a reservoir located in Inner Mongolia, China, in the winter of 2011, and the odor rating, algal density and concentrations of some potential odorous compounds were monitored over a period of two months. The peak odor rating of the fishy odor was 7 according to flavor profile analysis. Among the dominant algal species(two diatom and one chrysophyte species) observed during the survey, the chrysophyte Dinobryon sp. was the most abundant species, with the peak density recorded at 88,520 cells/mL. Seven potential algal metabolites including heptanal, 2,4-heptadienal, 2,4-decadienal, nonanal, 2-octenal, 2,6- nonadienal and hexanal were detected. The principal component analysis result showed that n-hexanal, n-heptanal and 2,4-decadienal, possibly the metabolites of diatoms, and 2,4-heptadienal, possibly the metabolite of Dinobryon sp., might have contributed to the fishy odor episode. This study demonstrated that the fishy odor episode in this reservoir might be caused by the abnormal growth of chrysophytes and diatoms under the ice-cover. | Yunyun Zhao Jianwei Yu Ming Su Wei An Min Yang | 2013 | Journal of Environmental Sciences2013，25，12： | 17 |

| 5 | Characterization of disinfection byproduct formation potential in 13 source waters in China显示文摘The formation potential of four trihalomethanes (THMFP) and seven haloacetic acids (HAA 7 FP) in 13 source waters taken from four major water basin areas in China was evaluated using the simulated distribution system (SDS) chlorination method.The specific ultraviolet absorbance (SUVA 254:the ratio of UV 254 to dissolved organic carbon (DOC)),which ranged between 0.9 and 5.0 L/(mg·m),showed that the organic compounds in different source waters exhibited different reactivities with chlorine.The HAA 7 FP of source waters ranged from 20 to 448 μg/L and the THMFP ranged from 29 to 259 μg/L.The HAA 7 FP concentrations were higher than the THMFP concentrations in all but one of the samples.Therefore,the risks of haloacetic acids (HAAs) should be of concern in some source waters.TCM (chloroform) and BDCM (bromodichloromethane) were the major THM constituents,while TCAA (trichloroacetic acid) and DCAA (dichloroacetic acid) were the major HAA species.Br-THM (brominated THM species) were much higher than BrHAA (brominated HAA species),and the formation of Br-DBP (Br-THM and Br-HAA) should be of concern when the bromide concentration is over 100 μg/L. | Junzhi Zhang Jianwei Yu Wei An Juan Liu Yongjing Wang Youjun Chen Jia Tai Min Yang | 2011 | Journal of Environmental Sciences2011，23，2： | 13 |
| 6 | Spatial and temporal variations of two cyanobacteria in the mesotrophic Miyun reservoir, China显示文摘Spatial variations in phytoplankton community within a large mesotrophic reservoir(Miyun reservoir, North China) were investigated in relation to variations in physico-chemical properties, nutrient concentrations, temperature and light conditions over a 5 month period in 2009. The dynamics of phytoplankton community was represented by the dominance of cyanobacteria through summer and fall, following with a short term dominance of chlorophyta in late fall, and a relatively high abundance of diatom in October; on the other hand, maximum phytoplankton biomass was recorded in the north shallow region of Miyun reservoir with a higher nutrients level. Particular attention was paid to the impacts of environmental conditions on the growth of two cyanobacteria genera, the toxin-producing Microcystis and the taste & odor-producing Oscillatoria. Microcystis biomass was in general greatly affected by water temperature and mixing depth/local water depth ratio in this reservoir, while the Oscillatoria biomass in the surface and middle layers was greatly affected by total dissolved phosphorus, and that in the bottom layer was related with the Secchi depth/local water depth ratio. Abundant Oscillatoria biomass was observed only in late September when Microcystis biomass decreased and allowed sufficient light go through. | Ming Su Jianwei Yu Shenling Pan Wei An Min Yang | 2014 | Journal of Environmental Sciences2014，26，2： | 9 |
| 7 | Advanced oxidation of bromide-containing drinking water: A balance between bromate and trihalomethane formation control显示文摘Addition of H2O2 has been employed to repress bromate formation during ozonation of bromide-containing source water.However,the addition of H2O2 will change the oxidation pathways of organic compounds due to the generation of abundant hydroxyl radicals,which could afect the removal efcacy of trihalomethane precursors via the combination of ozone and biological activated carbon(O3-BAC).In this study,we evaluated the efects of H2O2 addition on bromate formation and trihalomethane formation potential(THMFP)reduction during treatment of bromide-containing(97.6–129.1μg/L)source water by the O3-BAC process.At an ozone dose of 4.2 mg/L,an H2O2/O3(g/g)ratio of over 1.0 was required to maintain the bromate concentration below 10.0μg/L,while a much lower H2O2/O3ratio was sufcient for a lower ozone dose.An H2O2/O3(g/g)ratio below 0.3 should be avoided since the bromate concentration will increase with increasing H2O2 dose below this ratio.However,the addition of H2O2 at an ozone dose of 3.2 mg/L and an H2O2/O3 ratio of 1.0 resulted in a 43% decrease in THMFP removal when compared with the O3-BAC process.The optimum H2O2/O3(g/g) ratio for balancing bromate and trihalomethane control was about 0.7–1.0.Fractionation of organic materials showed that the addition of H2O2 decreased the removal efcacy of the hydrophilic matter fraction of DOC by ozonation and increased the reactivity of the hydrophobic fractions during formation of trihalomethane,which may be the two main reasons responsible for the decrease in THMFP reduction efcacy.Overall,this study clearly demonstrated that it is necessary to balance bromate reduction and THMFP control when adopting an H2O2 addition strategy. | Yongjing Wang Jianwei Yu Po Han Jing Sha Tao Li Wei An Juan Liu Min Yang | 2013 | Journal of Environmental Sciences2013，25，11： | 9 |
| 8 | Risk assessment of Giardia in rivers of southern China based on continuous monitoring显示文摘The occurrence and risks of Giardia in China have been unclear to date,which has made it difficult to properly manage source water as well as to create reasonable drinking water standards.The levels of Giardia in river networks of several cities in Zhejiang Province,China were found to be in the range of 0-5 oocysts/10 L in the rainy season in 2008.The mortality due to Giardia infection for people in this region was calculated to be from 0 to 1.95 × 10?8 persons using a conditional probability equation.Based on multiple unboiled water intake routes,the disability-adjusted life years(DALYs) due to Giardia infection for people who consumed conventionally treated water was 0.625(95% CI:0.137-2.05) per 105 persons,with the symptom of hospitalization making the highest contribution to total DALYs(0.56 per 105 persons;95% CI:0.122-1.84).The DALYs decreased to 0.425(95% CI:0.137-2.05) per 105 persons per year for those consuming water treated with advanced technology.These values were lower than the acceptable risk(1.97 × 10?5 DALYs per year).This study revealed the risk of Giardia infection to the people in river networks of Zhejiang Province for the first time,and provides a method to evaluate the risk of Giardia infection.The results are useful for the modification of drinking water quality standards based on cost-benefit analysis. | Wei An Dongqing Zhang Shumin Xiao Jianwei Yu Min Yang | 2012 | Journal of Environmental Sciences2012，24，2： | 8 |
| 9 | Identification of causative compounds and microorganisms for musty odor occurrence in the Huangpu River,China显示文摘There are regular problems of musty odor in the Huangpu River,a major source of drinking water for Shanghai,China.In this study,the musty odor and its main causative compounds in the Huangpu River source water were confirmed through a yearly investigation using flavor profile analysis combined with HSPME-GC-MS analysis.The investigation showed that 2-methylisoborneol (2-MIB) with a concentration level between 28.6 and 71.0 ng/L was responsible for the musty odor in summer from July to September.Microscopic observation confirmed with the cloning results showed that Phormidium spp.,which accounted for 80%-95% of the algal cell density,was the microorganisms responsible for the production of 2-MIB and the estimated 2-MIB yield was 0.022 pg/cell.Results from a wide-area sampling campaign in the Huangpu River watershed showed that,other than the large tributaries receiving water from Tai Lake,several small creeks close to the intake may have contributed most of the 2-MIB and the Phormidium spp.to the Huangpu River source water.This study provides methodology for the investigation of odor causing compounds and microorganisms in river-type source water,and the result will be useful for water quality control in both source water and drinking water. | Daolin Sun Jianwei Yu Wei An Min Yang Guoguang Chen Shujun Zhang | 2013 | Journal of Environmental Sciences2013，25，3： | 6 |

| 11 | Quantitative method to determine the regional drinking water odorant regulation goals based on odor sensitivity distribution:Illustrated using 2-MIB显示文摘Taste and odor(T/O) in drinking water often cause consumer complaints and are thus regulated in many countries. However, people in different regions may exhibit different sensitivities toward T/O. This study proposed a method to determine the regional drinking water odorant regulation goals(ORGs) based on the odor sensitivity distribution of the local population. The distribution of odor sensitivity to 2-methylisoborneol(2-MIB) by the local population in Beijing, China was revealed by using a normal distribution function/model to describe the odor complaint response to a 2-MIB episode in 2005, and a 2-MIB concentration of12.9 ng/L and FPA(flavor profile analysis) intensity of 2.5 was found to be the critical point to cause odor complaints. Thus the Beijing ORG for 2-MIB was determined to be 12.9 ng/L. Based on the assumption that the local FPA panel can represent the local population in terms of sensitivity to odor, and that the critical FPA intensity causing odor complaints was 2.5, this study tried to determine the ORGs for seven other cities of China by performing FPA tests using an FPA panel from the corresponding city. ORG values between 12.9 and 31.6 ng/L were determined, showing that a unified ORG may not be suitable for drinking water odor regulations. This study presents a novel approach for setting drinking water odor regulations. | Jianwei Yu Wei An Nan Cao Min Yang Junong Gu Dong Zhang Ning Lu | 2014 | Journal of Environmental Sciences2014，26，7： | 5 |
| 12 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |

| 16 | Finite-Time Stability for Interval Type-2 Fuzzy Nonlinear Systems via an Observer-Based Sliding Mode Control显示文摘This work focuses on the design of a sliding mode controller for a class of continuoustime interval type-2 fuzzy-model-based nonlinear systems with unmeasurable state information over a finite-time interval.Aiming at describing the nonlinearities containing parameter uncertainties that inevitably appear in practice,the interval type-2 fuzzy sets are employed to model the studied system.To improve the designing flexibility,a fuzzy observer model non-parallel distribution compensation scheme is designed to estimate the state information of the plant,i.e.,the observer is allowed to have a mismatching premise structure from the system.On this basis,the appropriate fuzzy sliding surface and fuzzy controller are constructed by following the same premise variables as the designed fuzzy observer.Then,by means of the sliding mode control theory and the Lyapunov function method,some novel sufficient criteria are established to ensure the finite-time boundedness for the studied systems via a partitioning strategy including the reaching phase,the sliding motion phase and the whole time interval.Furthermore,the designed gains are acquired by solving the matrix convex optimization problem.Finally,the effectiveness of the developed method is demonstrated by two simulation examples. | LIU Yu'an XIA Jianwei WANG Jing SHEN Hao | 2022 | Journal of Systems Science & Complexity2022，35，6： | 1 |
| 17 | Genetic variation of wood tracheid traits and their relationships with growth and wood density in clones of Pinus tabuliformis显示文摘To improve wood quality for pulpwood industries, it is important to examine not only wood density but also its components, especially tracheid characteristics.We studied genetic variations in the following tracheid traits by earlywood(EW) and latewood(LW): tracheid length(TL),double wall thickness(WT), radial lumen diameter(R_D1), tangential lumen diameter(T_D1), radial central diameter(R_D2), and tangential central diameter(T_D2).We also studied the relationship with the following growth traits: diameter at breast height(DBH), height(H), crown breadth south-north axis(NSC), crown breadth east–west axis(EWC), ring width(RW), latewood percentage (LWP), and wood density(WD).All sample materials were collected from a 33-year old clonal seed orchard of Pinus tabuliformis Carr.Genetic variation among clones was moderate for all tracheid traits, 9.49–26.03%.Clones significantly affected WT, R_D1, R_D2, T_D1, T_D2, and the two ratios WT/R_D1 and TL/T_D2 in EW but had no effects in LW.Clones significantly affected TL in LW but had no effects in EW.H2/C was higher in LW(0.50) than in EW(0.20) for TL, while H2/Cwas higher in EW(0.27–0.46)for other tracheid traits and the two ratios(TL/T_D2 and WT/R_D1) than in EW(0.06–0.22).WD and TL were significantly positively correlated, but WT and TL were negatively correlated both at individual and clone levels;all tracheid diameters and the four ratio values(EW_WT/R_D1, LW_WT/R_D1, EW_TL/T_D2 and LW_TL/T_D2), were strongly positively correlated with DBH, H,NSC, WEC and RW, and strongly negatively correlated with WD both at individual and clone levels.The most important variables for predicting WD were LW_TL,EW_WT and R_D1 in both EW and LW(r^2= 0.22).Selecting the top 10% of the clones by DBH would improve DBH growth by 12.19%(wood density was reduced by 0.14%) and produced similar responses between EW and LW for all tracheid traits: a reduction of0.94 and 3.69% in tracheid length and increases in tracheid diameters(from 0.36 to 5.24%) and double wall thickness(0.07 and 0.87%).The two ratios WT/R_D1 and TL/T_D2 across tissues(EW and LW) declined 0.59 and 4.56%,respectively.The decreased tracheid length and the ratio between tracheid length and diameter is disadvantageous for pulp production.The unfavorable relationship of tracheid traits with wood density indicate that multiple trait selection using optimal economic weights and optimal breeding strategies are recommended for the current longterm breeding program for P.tabuliformis. | Fangqun Ouyang Jianwei Ma Sanping An Junhui Wang Yuhui Weng | 2018 | Journal of Forestry Research2018，29，4： | 1 |
