| 1 | Arsenic hyperaccumulator Pteris Vittata L. and its arsenic accumulation显示文摘An arsenic hyperaccumulator Pteris vittata L. (Chinese brake) was first discovered in China by means of field survey and greenhouse cultivation. Field survey showed that Chinese brake had large accumulating capacity to arsenic; the orders of arsenic content in different parts of the fern were as follows: leaves>leafstalks>roots, which is totally different from that of ordinary plants; bioaccumulation coefficients of the above ground parts of the fern decreased as a power function of soil arsenic contents. In the control of pot trials with normal unpolluted soil containing 9mg/kg of arsenic, the bioaccumulation coefficients of the above ground parts and rhizoids of Chinese brake were as high as 71 and 80 respectively. Greenhouse cultivation in the contaminated soil from mining areas has shown that more than 1 times greater arsenic can be accumulated in the leaves of the fern than that of field samples with the largest content of 5070 mg/kg As on a dry matter basis. During greenhouse cultivation, arsenic | Tongbin Chen Chaoyang Wei Zechun Huang Qifei Huang Quanguo Lu Zilian Fan | 2002 | Chinese Science Bulletin2002，47，11： | 108 |

| 3 | Assessing the health risk of heavy metals in vegetables to the general population in Beijing,China显示文摘A systematic survey of As, Cd, Cr, Cu, Ni, Pb and Zn concentrations in vegetables from 416 samples (involving 100 varieties) in Beijing was carried out for assessing the potential health risk to local inhabitants. The results indicated that the metal concentrations in vegetables ranged from < 0.001 to 0.479 μg/g fresh weight (fw) (As), < 0.001 to 0.101 μg/g fw (Cd), < 0.001 to 1.04 μg/g fw (Cr), 0.024 to 8.25 μg/g fw (Cu), 0.001 to 1.689 μg/g fw (Ni), < 0.001 to 0.655 μg/g fw (Pb) and 0.01 to 25.6 μg/g fw (Zn), with average concentrations of 0.013, 0.010, 0.023, 0.51, 0.053, 0.046 and 2.55 μg/g fw, respectively. The results showed that the concentrations of As, Cr, Cu, Cd, Pb and Ni in vegetables from open-fields were all significantly higher than those grown in greenhouses. In addition, in local-produced vegetables, all HMs except Zn were significantly higher than those in provincial vegetables. The estimated daily intake (EDI) of As, Cd, Cr, Cu, Ni, Pb and Zn from vegetables was 0.080, 0.062, 0.142, 3.14, 0.327, 0.283 and 15.7 μg/(kg body weight (bw)·d) for adults, respectively. Arsenic was the major risk contributor for inhabitants since the target hazard quotient based on the weighted average concentration (THQw) of arsenic amounted to 44.3% of the total THQ (TTHQ) value according to average vegetable consumption. The TTHQ was lower than 1 for all age groups, indicating that it was still safe for the general population of Beijing to consume vegetables. | SONG Bo LEI Mei CHEN Tongbin ZHENG Yuanming XIE Yunfeng LI Xiaoyan GAO Ding | 2009 | Journal of Environmental Sciences2009，21，12： | 45 |
| 4 | Effect of phosphorus on arsenic accumulation in As-hyperaccumulator Pteris vittata L. and its implication显示文摘Pot experiment was conducted to understand the effect of phosphorus on arsenic accumulation in As-hyperaccumulator Chinese brake (Pteris vittata L.). It is shown that arsenic concentrations in the fronds and rhizoids, the arsenic bioaccumulation factor, and the total arsenic in the fronds were not influenced significantly under low levels of phosphorus (≤400 mg/kg) and increased sharply under high levels of phosphorus (>400 mg/ kg). The discovery implies that the efficiency of arsenic removal in phytoremedia-tion using the hyperaccumulating plant can be greatly elevated by the phosphorus addition at high rates. The interaction between the accumulation of phosphorus and that of arsenic in plant was stimulated mutually. The result represents that Chinese brake is a good material for plant physiologist to conduct comparative and mechanism studies on the uptake behaviors of phosphorus and arsenic, and phosphorus is also a potential accelerator for phytoremediation of arsenic-contaminated soils. | Tongbin Chen Zhilian Fan Mei Lei Zechun Huang Chaoyang Wei | 2002 | Chinese Science Bulletin2002，47，22： | 35 |
| 5 | Regional assessment of cadmium pollution in agricultural lands and the potential health risk related to intensive mining activities: A case study in Chenzhou City, China显示文摘The purpose of this study was to assess the extent of cadmium (Cd) contamination in agricultural soil and its potential risk for people. Soils, rice, and vegetables from Chenzhou City, Southern China were sampled and analyzed. In the surface soils, the 95% confidence interval for the mean concentration of Cd varied between 2.72 and 4.83 mg/kg (P < 0.05) in the survey, with a geometric mean concentration of 1.45 mg/kg. Based on the GIS map, two hot spot areas of Cd in agricultural soils with high Cd concentrations were identified to be located around the Shizhuyuan, Jinshiling, and Yaogangxian mines, and the Baoshan and Huangshaping mines, in the center of the city. About 60% of the total investigated area, where the agricultural soil Cd concentration is above 1 mg/kg, is distributed in a central belt across the region. The critical distances, at which the soil Cd concentration were increased by the mining activities, from the mines of the soils were 23 km for the Baoshan mine, 46 km for the Huangshaping mine, and 63 km for the Shizhuyuan mine, respectively. These are distances calculated from models. The Cd concentrations in rice samples ranged from 0.01 to 4.43 mg/kg and the mean dietary Cd intake from rice for an adult was 191 μg/d. Results of risk indexes showed that soil Cd concentrations possessed risks to local residents whose intake of Cd from rice and vegetables grown in soils in the vicinity of the mine was 596 μg/d. | ZHAI Limei LIAO Xiaoyong CHEN Tongbin YAN Xiulan XIE Hua WU Bin WANG Lixia | 2008 | Journal of Environmental Sciences2008，20，6： | 35 |
| 6 | Subcellular distribution and compartmentalization of arsenic in Pteris vittata L.显示文摘The subcellular distribution of arsenic (As) in Pteris vittata L., an As-hyperaccumulator, was studied to de- termine As compartmentalization and to explore the mecha- nisms that confer As tolerance. When the plant was grown in a nutrient solution without additional As, most of the accu- mulated As was isolated to the cell wall. However, in plants growing in a nutrient solution containing 0.1 or 0.2 mmol/L As, approximately 78% of the total As accumulated within the pinna. The proportions of As accumulation in the cyto- plasmic supernatant fraction were 78% of that in the pinna and 61% of that in the plant. In either treatment group (0.1 or 0.2 mmol/L As), the fraction containing the lowest level of As was the organelle fraction. These results suggest that As accumulates in the pinna where it is primarily distributed in the cytoplasmic supernatant fraction. The role of As com- partmentalization may be intricately linked with As detoxi- fication in P. vittata L. | CHEN Tongbin YAN Xiulan LIAO Xiaoyong XIAO Xiyuan HUANG Zechun XIE Hua ZHAI Limei | 2005 | Chinese Science Bulletin2005，50，24： | 17 |
| 7 | Cadmium accumulation and tolerance of two castor cultivars in relation to antioxidant systems显示文摘To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor(Ricinus communis L.) cultivars(Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment(0, 1 and 2 mg/L Cd) and a pot experiment using Cd-contaminated soil(34 mg/kg) with the addition of ethylenedinitrilotetraacetic acid(EDTA). The results indicated that there were significant differences between the two cultivars with respect to Cd uptake in shoots(113–248 mg/kg for Zibo No. 5 and 130–288 mg/kg Zibo No. 8), biomass tolerance indexes(64.9%–74.6% for Zibo No. 5 and 80.1%–90.9% for Zibo No. 8) in the hydroponic experiment and survival rates(0% for Zibo No. 5 and 100% for Zibo No. 8)determined by the addition of EDTA in the pot experiment, suggesting that Zibo No. 8 has higher tolerance than Zibo No. 5. Moreover, the castor cultivars have low bioconcentration factors(4.80% for Zibo No. 5 and 5.43% for Zibo No. 8) and low translocation factors(<1%).Consequently, Zibo No. 8 can participate in Cd phytostabilization in highly Cd-polluted areas. The results indicated that glutathione(GSH) as a non-enzymatic antioxidant, and antioxidant enzymes including superoxide dismutase(SOD), catalase(CAT) and guaiacol peroxidase(GPX), were cultivar- and dose-dependent. The higher tolerance of Zibo No. 8compared with Zibo No. 5 can be attributed to the higher GSH levels in the root and higher GPX activity in the leaf. | Hanzhi Zhang Qingjun Guo Junxing Yang Tongbin Chen Guangxu Zhu Marc Peters Rongfei Wei Liyan Tian Chunyu Wang Deyun Tan Jie Ma Gangming Wang Yingxin Wan | 2014 | Journal of Environmental Sciences2014，26，10： | 15 |

| 9 | EXAFS study on arsenic species and transformation in arsenic hyperaccumulator显示文摘Synchrotron radiation extended X-ray absorption fine structure (SR EXAFS) was employed to study the transformation of coordination environment and the redox speciation of arsenic in a newly discovered arsenic hyperaccumulator, Cretan brake (Pteris cretica L. var ner-vosa Thunb). It showed that the arsenic in the plant mainly coordinated with oxygen, except that some arsenic coordinated with S as As-GSH in root. The complexation of arsenic with GSH might not be the predominant detoxification mechanism in Cretan brake. Although some arsenic in root presented as As(V) in Na2HAsO4 treatments, most of arsenic in plant presented as As(III)-O in both treatments, indicating that As(V) tended to be reduced to As(III) after it was taken up into the root, and arsenic was kept as As(III) when it was transported to the above-ground tissues. The reduction of As(V) primarily proceeded in the root. | HUANG Zechun1, CHEN Tongbin1, LEI Mei1, HU Tiandou2 & HUANG Qifei1 1.

| 10 | Role of trichome of Pteris vittata L. in arsenic hyperaccu-mulation显示文摘Environmental scanning electron microscope (ESEM) fitted with an energy disper- sive X-ray microanalyzer (EDX) was used to investigate the surface micromorphology and arse- nic (As) micro-distribution in Chinese brake (Pteris vittata L.). It was found that amounts of trichome, which possessed multicellular structure with the average length of 160 μm and with an average diameter of 28 μm, existed in the frond of P. vittata, and the density of trichome on the pinnate axial surface was higher than that on the petiole. Visible X-ray peak of As was recorded in the epidermal cell and trichome. The relative weight of As in the pinnate trichome, which con- tained the highest concentration of As among all tissues of the plant, was 2.4 and 3.9 times as much as that in the epidermal and mesophyllous cells, respectively. The As concentrations in the basal and stalk cells of the same trichome were higher than that in its cap cell. This is the first time to report that the trichome of P. vittata plays an important role in arsenic hyperaccumulation. The finding from the present study implies that much attention should be paid to the role of the trichome in understanding the hyperaccumulation and detoxicity of As in the hyperaccumulator and improving the ability of As accumulation. | LI Wenxue CHEN Tongbin CHEN Yang LEI Mei | 2005 | Science China(Life Sciences)2005，48，2： | 10 |
| 11 | Distributions of arsenic and essential elements in pinna of arsenic hyperaccumulator Pteris vittata L.显示文摘The distributions of arsenic and 6 essential elements in the pinna of As hyperaccumulator, Pteris vittata L., were studied using synchrotron radiation X-ray fluorescence (SRXRF). Significant correlation between the distribution and mobility of the elements revealed that SRXRF study on the elemental distribution was feasible to inspect the transportations of elements in plants. The distribution of As in the pinna showed that As had great abilities to be transported in xylem vessels and from xylem to mesophyll. The distribution of K, one of the most mobile elements in plants, was similar to that of As, whereas the distributions of Fe and Ca with less mobility in plants were almost opposite to that of As in the pinna. | CHEN Tongbin, HUANG Zechun, HUANG Yuying & LEI Mei Laboratory of Environmental Remediation, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Laboratory of Synchrotron Radiation, Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100039, China | 2005 | Science China(Life Sciences)2005，48，1： | 7 |
| 12 | Application of sewage sludge and intermittent aeration strategy to the bioremediation of DDT- and HCH-contaminated soil显示文摘Adding organic amendments to stimulate the biodegradation of pesticides is a subject of ongoing interest. The effect of sewage sludge on the bioremediation of dichlorodiphenyltrichloroethane(DDT) and hexachlorocyclohexane(HCH) contaminated soil was investigated in bench scale experiments,and intermittent aeration strategy was also used in this study to form an anaerobic–aerobic cycle. Bioremediation of DDT and HCH was enhanced with the addition of sewage sludge and the intermittent aeration. The removal rates of HCH and DDT were raised by 16.8%–80.8% in 10 days. Sewage sludge increased the organic carbon content from 6.2 to218 g/kg,and it could also introduce efficient degradation microbes to soil,including Pseudomonas sp.,Bacillus sp. and Sphingomonas sp. The unaerated phase enhanced the anaerobic dechlorination of DDT and HCH,and anaerobic removal rates of β-HCH,o,p′-DDT and p,p′-DDT accounted for more than 50% of the total removal rates,but the content of α-HCH declined more in the aerobic phase. | Qi Liang Mei Lei Tongbin Chen Jun Yang Xiaoming Wan Sucai Yang | 2014 | Journal of Environmental Sciences2014，26，8： | 5 |
| 13 | Changes in hair arsenic concentration in a population exposed to heavy pollution:Follow-up investigation in Chenzhou City,Hunan Province,Southern China显示文摘Follow-up investigation on hair arsenic concentration was conducted in an arsenic heavily polluted area of southern China in 2002 and 2006.The results showed that the geometric mean of hair arsenic concentration decreased from 2.95 mg/kg in 2002 to 1.78 mg/kg in 2006,when the percentage of the population with levels over 1 mg/kg only decreased from 93.4% in 2002 to 80.5% in 2006.Over this four-year period,the population with high arsenic concentrations decreased significantly while there was no obvious change in hair arsenic concentration for people who had relatively low concentrations.In terms of age distribution,young and old people had higher hair arsenic concentrations than the middle-aged.All of these results showed that it is difficult to reverse the negative impact of arsenic pollution on human health.Arsenic pollution has a long-term continuous influence on the health of local residents. | Bin Wu,Tongbin Chen Center for Environmental Remediation,Institute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences,Beijing 100101,China. | 2010 | Journal of Environmental Sciences2010，22，2： | 4 |

| 17 | Relationship Between Soil Properties and Different Fractions of Soil Hg显示文摘Correlation and path analysis methods were used to study the relationship between soil properties and the distribution of different soil Hg fractions with nine representative soils from Chongqing, China. Results showed that clay (< 2 m) could increase water-soluble Hg (r = 0.700*). Soil organic matter (OM) could enhance the increase of elemental Hg (r = 0.674*). The higher the base saturation percentage (BSP), the more the residual Hg (T = 0.684*). Organic Hg, the sum of acid-soluble organic Hg and alkali-soluble Hg, was positively affected by silt (2-20 μm) but negatively affected by pH, with the direct path coefficients amounting to 1.0487 and 0.5121, respectively. The positive effect of OM and negative effect of BSP on organic Hg were the most significant, with the direct path coefficients being 0.7614 and -0.8527, respectively. The indirect effect of clay (< 2 μm) via BSP (path coefficient = 0.4186) was the highest, showing that the real influencing factor in the effect of clay (< 2 μm) on acid-soluble organic Hg was BSP. Since the available Hg fraction, water-soluble Hg, was positively affected by soil clay content, and the quite immobile and not bioavailable residual Hg by soil BSP, suitable reduction of clay content and increase of BSP would be of much help to reduce the Hg availability and Hg activity in Hg-contaminated soils. | WU HONGTAO YU GUIFEN QING CHANGLE and CHEN TONGBIN Southwest Agricultural University, Chongqing 400716 (China) Institute of Geographic Sciences and Natural Resources, the Chinese Academy of Sciences, Beijing 100101 (China) Institute of Soil Science, th | 2001 | Pedosphere2001，11，3： | 2 |

| 19 | Identifying factors that influence soil heavy metals by using categorical regression analysis:A case study in Beijing,China显示文摘Identifying the factors that influence the heavy metal contents of soil could reveal the sources of soil heavy metal pollution.In this study,a categorical regression was used to identify the factors that influence soil heavy metals.First,environmental factors were associated with soil heavy metal data,and then,the degree of influence of different factors on the soil heavy metal contents in Beijing was analyzed using a categorical regression.The results showed that the soil parent material,soil type,land use type,and industrial activity were the main influencing factors,which suggested that these four factors were important sources of soil heavy metals in Beijing.In addition,population density had a certain influence on the soil Pb and Zn contents.The distribution of soil As,Cd,Pb,and Zn was markedly influenced by interactions,such as traffic activity and land use type,industrial activity and population density.The spatial distribution of soil heavy metal hotspots corresponded well with the influencing factors,such as industrial activity,population density,and soil parent material.In this study,the main factors affecting soil heavy metals were identified,and the degree of their influence was ranked.A categorical regression represents a suitable method for identifying the factors that influence soil heavy metal contents and could be used to study the genetic process of regional soil heavy metal pollution. | Jun Yang Jingyun Wang Pengwei Qiao Yuanming Zheng Junxing Yang Tongbin Chen Mei Lei Xiaoming Wan Xiaoyong Zhou | 2020 | Frontiers of Environmental Science & Engineering2020，14，3： | 1 |
