| 1 | Influence of soil type and genotype on Cd bioavailability and uptake by rice and implications for food safety显示文摘Cadmium(Cd) entering the human body via the food chain is of increasing concern.This study investigates the effects of soil type and genotype on variations in the Cd concentrations of different organs of nine rice plants grown on two types of soils with two Cd levels.Cd concentrations in nine rice cultivars varied significantly with genotype and soil type(P < 0.01).The Cd concentration was higher in red paddy soil(RP) than in yellow clayey paddy soil(YP).The average Cd concentrations of different organs in three rice types were indica > hybrid > japonica for the Cd treatments and controls.The polished grain concentration in YP and RP soils had a range of 0.055-0.23 mg/kg and 0.13-0.36 mg/kg in the Cd treatment,respectively.Two rice cultivars in YP soil and five rice cultivars in RP soil exceeded the concentration limits in the Chinese Food Hygiene Standard(0.2 mg/kg).The Cd concentrations in roots,stems,and leaves were all significantly and positively correlated to that in polished grain in a single test.The Cd concentrations in polished grain were positively and significantly(P < 0.01) correlated with the calculated transfer factors of stem to grain and leaf to grain Cd transfer.The results indicated that the variations of Cd concentration in grain were related to Cd uptake and the remobilization of Cd from stem and leaf to grain.Also,the cultivars with a strong tendency for Cd-accumulation should be avoided in paddy soil with low soil pH and low organic matter content to reduce the risks to human health from high Cd levels in rice. | Xinxin Ye Yibing Ma Bo Sun | 2012 | Journal of Environmental Sciences2012，24，9： | 34 |

| 3 | Genotypic variations in the accumulation of Cd exhibited by different vegetables显示文摘It is an important approach to use the Cd-contaminated soils properly by growing low accumulator or excluder plants for Cd to produce safe foods. To find the suitable vegetable species for growing in Cd-contaminated soils, in the present study the variations in the Cd accumulation for twenty eight vegetable species and several cultivars of five common vegetables (cowpea, kidney pea, bitter gourd, cucumber and squash) were investigated in two soil Cd levels (1 and 2 mg/kg Cd). Experimental results showed that highly significant differences in Cd concentration were evident among 28 vegetables. For example, spinach Cd concentrations were 110-fold and 175-fold higher than that of sweet pea under the 1 and 2 mg/kg Cd exposures, respectively. For Cd accumulation, the order of vegetable species was: leafy vegetables > solanaceous vegetables > kale vegetables > root vegetables > allimus > melon vegetables > legumes. Distinctive differences were also identified when comparing different cultivars of the five common vegetables with an average range of 0.003–0.094 mg/kg Cd. Our results indicated that a large genotypic variation existed among vegetable species or cultivars when subjected to Cd exposure. Therefore, it is important and feasible to elect/breed vegetable species/cultivars with low accumulation of Cd, especially in mildly Cd-contaminated soils. | Junxing Yang Haitao Guo Yibing Ma Liqun Wang Dongpu Wei Luo Hua | 2010 | Journal of Environmental Sciences2010，22，8： | 16 |
| 4 | A highly porous animal bone-derived char with a superiority of promoting nZVI for Cr(Ⅵ)sequestration in agricultural soils显示文摘Paddy soil and irrigation water are commonly contaminated with hexavalent chromium[Cr(Ⅵ)]near urban industrial areas,thereby threatening the safety of agricultural products and human health.In this study,we develop a porous and high specific area bone char(BC)to support nanoscale zero-valent iron(n ZVI)and apply it to remediate Cr(Ⅵ)pollution in water and paddy soil under anaerobic conditions.The batch experiments reveal that BC/n ZVI exhibits a higher removal capacity of 516.7 mg/(g·n ZVI)for Cr(Ⅵ)than n ZVI when normalized to the actual n ZVI content,which is 2.8 times that of n ZVI;moreover,the highest n ZVI utilization is the n ZVI loading of 15%(BC/n ZVI15).The Cr(Ⅵ)removal efficiency of BC/n ZVI15 decreases with increasing p H(4–10).Coexisting ions(phosphate and carbonate)and humic acid can inhibit the removal of Cr(Ⅵ)with BC/n ZVI15.Additionally,BC exhibits a strong advantage in promoting Cr(Ⅵ)removal by n ZVI compared to the widely used biochar and activated carbon.Our results demonstrate that reduction and coprecipitation are the dominant Cr(Ⅵ)removal mechanisms.Furthermore,BC/n ZVI15 shows a significantly higher reduction and removal efficiency as well as a strong anti-interference ability for Cr(Ⅵ)in paddy soil,as compared to n ZVI.These findings provide a new effective material for remediating Cr(Ⅵ)pollution from water and soil. | Kai Liu Fangbai Li Qingwen Tian Chengrong Nie Yibing Ma Zhenlong Zhu Liping Fang Yuanying Huang Siwen Liu | 2021 | Journal of Environmental Sciences2021，33，6： | 7 |
| 5 | Can phosphate compounds be used to reduce the plant uptake of Pb and resist the Pb stress in Pb-contaminated soils?显示文摘The effects of different phosphate-amendments on lead(Pb) uptake,the activities of superoxide dismutase(SOD) and the level of malondialdehyde(MDA) in cauliflower(Brassica oleracea L.) in contaminated soils with 2500,or 5000 mg P2O5/kg soil of hydroxyapatite(HA),phosphate rock(PR),single-superphosphate(SSP) and the mix of HA/SSP(HASSP) were evaluated in pot experiments.Results showed that the Pb concentrations in shoots and roots decreased by 18.3%-51.6% and 16.8%-57.3% among the treatments respectively compared to the control samples.The effciency order of these phosphate-amendments in reducing Pb uptake was as follows:HASSP≈ HA > SSP ≈ PR.With the addition of SSP,HA and the mix of HA/SSP,the SOD activity in shoot was reduced markedly(P < 0.05) compared with that in the control group.For example,the SOD activities in shoot by the treatments of HASSP,SSP,and HA in 5000 mg P2O5/kg were found to be only 51.3%,56.2%,and 56.7%,respectively.Similar effects were also observed on the level of MDA in the shoots with a decrease in 24.5%-56.3%.The results verified the inference that phosphate compounds could be used to reduce the plant uptake of Pb and resist the Pb stress in the plant vegetated in Pb-contaminated soils. | CHEN Shibao CHEN Li MA Yibing HUANG Yizong | 2009 | Journal of Environmental Sciences2009，21，3： | 3 |

| 7 | Rice(Oryza sativa L.)seedlings enriched with zinc or manganese:Their impacts on cadmium accumulation and expression of related genes显示文摘Cadmium(Cd)contamination in paddy soils means that the rice produced there may be unsafe for human consumption.A hydroponic study was conducted to enrich rice seedlings with zinc(Zn)or manganese(Mn),and the uptake and transport characteristics of Cd in these Zn-and Mn-rich seedlings were subsequently investigated using a greenhouse pot trial.The results showed that hydroponic cultivation in 10-50μmol L^(-1) Zn(ZnSO_(4)·7 H_(2)O)or50-250μmol L^(-1) Mn(MnSO_(4)·H_(2)O)for 30 d had no significant impact on rice growth,while the accumulation of Zn and Mn was 7.31-18.5 and 25.4-47.7 times higher,respectively,than in the control(no Zn or Mn addition).The accumulation of Cd in the Zn-and Mn-rich rice plants was 26.3%-38.6% and 34.4%-44.5% lower than that in the control,respectively,and the translocation factors of Cd from roots to shoots also decreased by 23.3%-41.3% and 25.3%-37.0%,respectively,after transplanting to Cd-contaminated soils.Furthermore,the relative expression levels of OsIRT1(Oryza sativa iron-regulated transporter 1)were downregulated by 40.1%-59.3% and 16.0%-25.9%,respectively,in the Zn-and Mn-rich seedling roots.This downregulation may indicate a possible mechanism contributing to the reductions in Cd absorption.Field experiments confirmed that the Zn-and Mn-rich seedlings produced brown rice(unpolished rice grains)with significantly decreased concentrations of Cd(34.2%-44.4%).This study provides an innovative method for reducing the food safety risks from rice grown on slightly to moderately Cd-contaminated paddy soils. | Gaoxiang HUANG Changfeng DING Yibing MA Yurong WANG Zhigao ZHOU Shun'an ZHENG Xingxiang WANG | 2021 | Pedosphere2021，31，6： | 2 |
| 8 | Selected dark sides of biomass-derived biochars as environmental amendments显示文摘With the rapid increase in the application of biochars as amendments, studies are needed to clarify the possible environmental risks derived from biochars to use safely the biomass resources. This work reported selected dark sides of maize straw-and swine manurederived biochars pyrolyzed at 300 and 500°C. During the pyrolysis processes, total heavy metals in the biochars were enriched greatly accompanying with considerable emission of the heavy metals into atmosphere and the trends became increasingly obvious with pyrolysis temperature. Meanwhile, the biochars showed distinctly decreased available heavy metals compared with raw feedstocks, which could be mainly attributed to the sorption by the inorganics in the biochars. The water-and acid-washing treatments significantly increased the releasing risks of heavy metals from biochars into the environments. Electron paramagnetic resonance analysis indicated that persistent free radicals, emerged strongly in the biochars as a function of the aromatization of biomass feedstocks, were free from the influence of water-, acid-, or organic-washing of the biochars and could remain stable even after aged in soils for 30 days. Dissolved biochars, highly produced during pyrolysis processes, showed distinct properties including lower molecular weight distribution while higher aromaticity compared with soil dissolved organic carbon.The results of this study provide important perspectives on the safe usage of biochars as agricultural/environmental amendments. | Zien Chen Lei Luo Diyi Xiao Jitao Lv Bei Wen Yibing Ma Shuzhen Zhang | 2017 | Journal of Environmental Sciences2017，29，4： | 2 |

| 17 | Using DGT to Assess Cadmium Bioavailability to Ryegrass as Influenced by Soil Properties显示文摘A generally accepted method for predicting the bioavailability and transfer of cadmium(Cd) from soil to plants has not yet been established. In this study, the diffusive gradients in thin films(DGT) and conventional extraction methods for metal fractions were used to investigate how effective these methods were at predicting Cd bioavailability to ryegrass(Lolium perenne) and to assess whether these holistic variables were independent of the soil property variables. The influences of soil properties on the predictive capabilities of the different methods were evaluated using multivariate statistics. The Cd concentrations in the shoots and roots of ryegrass correlated more closely with the effective Cd concentration measured by DGT(CE), compared with those with soil total Cd, pore water Cd, and ethylenediaminetetraacetic acid disodium salt(Na2EDTA)- and acetic acid(HOAc)-extractable Cd. When soil properties were included in a stepwise multiple linear regression, Cd transfer to L. perenne was negatively influenced by p H and positively influenced by organic matter(OM). The multivariate statistics showed that the adjusted correlation coefficients for the plots involving soil total Cd, pore water Cd, and Na2EDTA- and HOAc-extractable Cd had been significantly improved after considering the influences of soil properties, which suggested that these methods were p H and OM dependent. For CE, the relationship was p H independent or only dependent in strongly acidic soils. These results suggested that the main soil factors affecting bioavailability had the lowest impact on the DGT technique. Therefore, the DGT technique provided significant advantages over conventional methods when assessing Cd bioavailability. | SONG Ningning WANG Fangli MA Yibing TANG Shirong | 2015 | Pedosphere2015，25，6： | 1 |
| 18 | Homotypic clustering of L1 and B1/Alu repeats compartmentalizes the 3D genome显示文摘Organization of the genome into euchromatin and heterochromatin appears to be evolutionarily conserved and relatively stable during lineage differentiation.In an effort to unravel the basic principle underlying genome folding,here we focus on the genome itself and report a fundamental role for L1(LINE1 or LINE-1)and B1/Alu retrotransposons,the most abundant subclasses of repetitive sequences,in chromatin compartmentalization.We find that homotypic clustering of L1 and B1/Alu demarcates the genome into grossly exclusive domains,and characterizes and predicts Hi-C compartments.Spatial segregation of L1-rich sequences in the nuclear and nucleolar peripheries and B1/Alu-rich sequences in the nuclear interior is conserved in mouse and human cells and occurs dynamically during the cell cycle.In addition,de novo establishment of L1 and B1 nuclear segregation is coincident with the formation of higher-order chromatin structures during early embryogenesis and appears to be critically regulated by L1 and B1 transcripts.Importantly,depletion of L1 transcripts in embryonic stem cells drastically weakens homotypic repeat contacts and compartmental strength,and disrupts the nuclear segregation of L1-or B1-rich chromosomal sequences at genome-wide and individual sites.Mechanistically,nuclear co-localization and liquid droplet formation of L1 repeat DNA and RNA with heterochromatin protein HP1αsuggest a phase-separation mechanism by which L1 promotes heterochromatin compartmentalization.Taken together,we propose a genetically encoded model in which L1 and B1/Alu repeats blueprint chromatin macrostructure.Our model explains the robustness of genome folding into a common conserved core,on which dynamic gene regulation is overlaid across cells. | J.Yuyang Lu Lei Chang Tong Li Ting Wang Yafei Yin Ge Zhan Xue Han Ke Zhang Yibing Tao Michelle Percharde Liang Wang Qi Peng Pixi Yan Hui Zhang Xianju Bi Wen Shao Yantao Hong Zhongyang Wu Runze Ma Peizhe Wang Wenzhi Li Jing Zhang Zai Chang Yingping Hou Bing Zhu Miguel Ramalho-Santos Pilong Li Wei Xie Jie Na Yujie Sun Xiaohua Shen | 2021 | Cell Research2021，31，6： | 1 |
