| 1 | Health risk assessment of heavy metals in soils and vegetables from wastewater irrigated area,Beijing-Tianjin city cluster,China显示文摘The possible health risks of heavy metals contamination to local population through food chain were evaluated in Beijing and Tianjin city cluster,China,where have a long history of sewage irrigation.The transfer factors(TF) for heavy metals from soil to vegetables for six elements including Cu,Zn,Pb,Cr,As and Cd were calculated and the pollution load indexes(PLI) were also assessed.Results indicate that only Cd exceeded the maximum acceptable limit in these sites.So far,the heavy metal concentrations in soils and vegetables were all below the permissible limits set by the Ministry of Environmental Protection of China and World Health Organization.The transfer factors of six heavy metals showed the trend as Cd > Zn > Cu > Pb > As > Cr,which were dependent on the vegetable species.The estimated dietary intakes of Cu,Zn,Pb,Cr,As and Cd were far below the tolerable limits and the target hazard quotient(THQ) values were less than 1,which suggested that the health risks of heavy metals exposure through consuming vegetables were generally assumed to be safe. | Yanchun Wang Min Qiao Yunxia Liu Yongguan Zhu | 2012 | Journal of Environmental Sciences2012，24，4： | 52 |
| 2 | A review on completing arsenic biogeochemical cycle: Microbial volatilization of arsines in environment显示文摘Arsenic(As) is ubiquitous in the environment in the carcinogenic inorganic forms, posing risks to human health in many parts of the world. Many microorganisms have evolved a series of mechanisms to cope with inorganic arsenic in their growth media such as transforming As compounds into volatile derivatives. Bio-volatilization of As has been suggested to play an important role in global As biogeochemical cycling, and can also be explored as a potential method for arsenic bioremediation. This review aims to provide an overview of the quality and quantity of As volatilization by fungi, bacteria, microalga and protozoans. Arsenic bio-volatilization is influenced by both biotic and abiotic factors that can be manipulated/elucidated for the purpose of As bioremediation. Since As biovolatilization is a resurgent topic for both biogeochemistry and environmental health, our review serves as a concept paper for future research directions. | Peipei Wang Guoxin Sun Yan Jia Andrew A Meharg Yongguan Zhu | 2014 | Journal of Environmental Sciences2014，26，2： | 22 |
| 3 | QMEC:a tool for high-throughput quantitative assessment of microbial functional potential in C,N,P,and S biogeochemical cycling显示文摘Microorganisms are major drivers of elemental cycling in the biosphere. Determining the abundance of microbial functional traits involved in the transformation of nutrients, including carbon(C), nitrogen(N), phosphorus(P) and sulfur(S), is critical for assessing microbial functionality in elemental cycling. We developed a high-throughput quantitative-PCR-based chip, Quantitative microbial element cycling(QMEC), for assessing and quantifying the genetic potential of microbiota to mineralize soil organic matter and to release C, N, P and S. QMEC contains 72 primer pairs targeting 64 microbial functional genes for C, N, P, S and methane metabolism. These primer pairs were characterized by high coverage(average of 18–20 phyla covered per gene)and sufficient specificity(>70% match rate) with a relatively low detection limit(7–102 copies per run). QMEC was successfully applied to soil and sediment samples, identifying significantly different structures, abundances and diversities of the functional genes(P<0.05). QMEC was also able to determine absolute gene abundance. QMEC enabled the simultaneous qualitative and quantitative determination of 72 genes from 72 samples in one run, which is promising for comprehensively investigating microbially mediated ecological processes and biogeochemical cycles in various environmental contexts including those of the current global change. | Bangxiao Zheng Yongguan Zhu Jordi Sardans Josep Penuelas Jianqiang Su | 2018 | Science China(Life Sciences)2018，61，12： | 18 |
| 4 | Profiling the ionome of rice and its use in discriminating geographical origins at the regional scale, China显示文摘Element profile was investigated for their use to trace the geographical origin of rice (Oryza sativa L.) samples. The concentrations of 13 elements (calcium (Ca), potassium (K), magnesium (Mg), phosphorus (P), boron (B), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), arsenic (As), selenium (Se), molybdenum (Mo), and cadmium (Cd)) were determined in the rice samples by inductively coupled plasma optical emission and mass spectrometry. Most of the essential elements for human health in rice were within normal ranges except for Mo and Se. Mo concentrations were twice as high as those in rice from Vietnam and Spain. Meanwhile, Se concentrations were three times lower in the whole province compared to the Chinese average level of 0.088 mg/kg. About 12% of the rice samples failed the Chinese national food safety standard of 0.2 mg/kg for Cd. Combined with the multi-elemental profile in rice, the principal component analysis (PCA), discriminant function analysis (DFA) and Fibonacci index analysis (FIA) were applied to discriminate geographical origins of the samples. Results indicated that the FIA method could achieve a more effective geographical origin classification compared with PCA and DFA, due to its efficiency in making the grouping even when the elemental variability was so high that PCA and DFA showed little discriminatory power. Furthermore, some elements were identified as the most powerful indicators of geographical origin: Ca, Ni, Fe and Cd. This suggests that the newly established methodology of FIA based on the ionome profile can be applied to determine the geographical origin of rice. | Gang Li Luis Nunes Yijie Wang Paul N.

| 7 | Effects of microbial processes on the fate of arsenic in paddy soil显示文摘Arsenic(As) is a metalloid toxic to organisms including humans.Arsenic in rice represents a significant exposure pathway for the general population,particularly for those subsisting on rice.Arsenic transformation,namely reduction,oxidation and methylation,in soil-rice systems has fundamental impacts on its mobility and toxicity.In addition to soil chemical properties(pH,Eh,metallic oxides,organic matter),microorganisms play critical roles in As transformation and mobility in paddy soil,such as through ArsM(As(III) S-adenosylmethyltransferase) and interactions with iron oxides or organic matters.Arsenic species in paddy soil directly influence As speciation in rice grain because the methylated As species in rice are mainly derived from microbial methylation in paddy soil.This paper aims to provide an overview on the status of the knowledge and gaps on the chemical aspects of As transformation in soil-rice system in conjunction with microbial ecology and functional genes.In addition,potential pathways(manipulation of microorganisms in paddy soil and genetic engineering) to decrease total As and/or inorganic As in rice grain are proposed. | ZHENG RuiLun SUN GuoXin ZHU YongGuan | 2013 | Chinese Science Bulletin2013，58，2： | 7 |
| 8 | Understanding sustainability of soil and water resources in a critical zone perspective显示文摘Soil and water resources are fundamental for human beings.Understanding the status and the evolution of regional water and soil resources is the prerequisite for their sustainable management.China is severely constrained by water and soil resources which are subject to soil forming processes under different natural factors such as climate and relief,and also influenced by diversified landuse histories and intensities.Quality and security of water and soil resources are therefore influenced by both natural and anthropogenic processes. | Ganlin ZHANG Yongguan ZHU Ming'an SHAO | 2019 | Science China Earth Sciences2019，62，11： | 7 |
| 9 | Evaluation of genotoxicity of combined soil pollution by cadmium and imidacloprid显示文摘Cadmium (Cd) is one of the important pollutants of soil and the genotoxicity of Cd-contaminated soil was studied in combination with imidacloprid. The single cell gel electrophoresis or comet assay was used to quantify DNA strand breaks as a measure of DNA damage induced by Cd and imidacloprid contamination in soil. The soil was artificially contaminated by Cd 2 h at 25℃ and were used in the comet assay. DNA damage was measured as the values of percentage of nuclei with tails, tail length, tail DNA, tail moment (TM), and Olive tail moment (OTM). DNA damages of root tips of Vicia faba increased after Cd treatment and there were dose-related increases in DNA damage measured as these parameters. However, the addition of imidacloprid further increased the DNA damage. These data confirmed the genotoxic effect of Cd to plants, and that the combined pollution with imidacloprid can enhance the genotoxicity of Cd. | LIN Aijun ZHU Yongguan TONG Yiping | 2005 | Science China(Life Sciences)2005，48，z1： | 6 |
| 10 | Arsenic methylation by an arsenite S-adenosylmethionine methyltransferase from Spirulina platensis显示文摘Arsenic-contaminated water is a serious hazard for human health. Plankton plays a critical role in the fate and toxicity of arsenic in water by accumulation and biotransformation.Spirulina platensis(S. platensis), a typical plankton, is often used as a supplement or feed for pharmacy and aquiculture, and may introduce arsenic into the food chain, resulting in a risk to human health. However, there are few studies about how S. platensis biotransforms arsenic. In this study, we investigated arsenic biotransformation by S. platensis. When exposed to arsenite(As(Ⅲ)), S. platensis accumulated arsenic up to 4.1 mg/kg dry weight.After exposure to As(Ⅲ), arsenate(As(Ⅴ)) was the predominant species making up 64% to86% of the total arsenic. Monomethylarsenate(MMA(Ⅴ)) and dimethylarsenate(DMA(Ⅴ))were also detected. An arsenite S-adenosylmethionine methyltransferase from S. platensis(Sp Ars M) was identified and characterized. Sp Ars M showed low identity with other reported Ars M enzymes. The Escherichia coli AW3110 bearing Spars M gene resulted in As(Ⅲ) methylation and conferring resistance to As(Ⅲ). The in vitro assay showed that Sp Ars M exhibited As(Ⅲ) methylation activity. DMA(Ⅴ) and a small amount of MMA(Ⅴ) were detected in the reaction system within 0.5 hr. A truncated Sp Ars M derivative lacking the last 34 residues still had the ability to methylate As(Ⅲ). The three single mutants of Sp Ars M(C59S, C186 S, and C238S) abolished the capability of As(Ⅲ) methylation, suggesting the three cysteine residues are involved in catalysis. We propose that Sp Ars M is responsible for As methylation and detoxification of As(Ⅲ) and may contribute to As biogeochemistry. | Yuqing Guo Ximei Xue Yu Yan Yongguan Zhu Guidi Yang Jun Ye | 2016 | Journal of Environmental Sciences2016，28，11： | 5 |
| 11 | Growth and metal uptake of energy sugarcane (Saccharum spp.) in different metal mine tailings with soil amendments显示文摘A pot experiment was conducted to investigate the feasibility of growing energy sugarcane(Saccharum spp.) in three different metal mine tailings(Cu, Sn and Pb/Zn tailings) amended with uncontaminated soil at different mixing ratios. The results indicated that sugarcane was highly tolerant to tailing environments. Amendments of 20% soil to Sn tailings and 30% soil to Cu tailings could increase the biomass of cane-stem for use as the raw material for bioethanol production. Heavy metals were mostly retained in roots, which indicated that sugarcane was useful for the stabilization of the tailings. Bagasse and juice, as the most valuable parts to produce bioethanol, only accounted for 0.6%– 3% and 0.6%–7% of the total metal content. Our study supported the potential use of sugarcane for tailing phytostabilization and bioenergy production. | Xin Zhang Yongguan Zhu Yuebin Zhang Yunxia Liu Shaochun Liu Jiawen Guo Rudan Li Songlin Wu Baodong Chen | 2014 | Journal of Environmental Sciences2014，26，5： | 4 |

| 13 | High starter phosphorus fertilization facilitates soil phosphorus turnover by promoting microbial functional interaction in an arable soil显示文摘Microbial phosphorus(P)turnover is critical in C utilization efficiency in agroecosystems.It is therefore necessary to understand the P mobilization processes occurring during P fertilization in order to ensure both crop yield and environmental quality.Here,we established a controlled pot experiment containing soil amended with three different levels of starter P fertilizer and collected soil samples after 30,60,and 90 days of incubation.Quantitative microbial element cycling(QMEC)smart chip technology and 16S rRNA gene sequencing were used to investigate functional gene structures involved in carbon,nitrogen and P cycling and the bacterial community composition of the collected samples.Although P fertilization did not significantly affect the structure of the soil microbial community,some rare microbiota were changed in particular phosphorus-solubilizing bacteria were enriched at the high P fertilization level,suggesting that the rare taxa make an important contribution to P turnover.P fertilization also altered the functional gene structure,and high P concentrations enhanced the functional gene diversity and abundance.Partial redundancy analysis further revealed that changes in rare taxa and functional genes of soil microorganisms drive the alteration of soil P pools.These findings extend our understanding of the microbial mechanisms of P turnover. | Hongzhe Li Qingfang Bi Kai Yang Simon bo Lasson Bangxiao Zheng Li Cui Yongguan Zhu Kai Ding | 2020 | Journal of Environmental Sciences2020，32，8： | 3 |
| 14 | Spatial patterns of urban green space and its actual utilization status in China based on big data analysis显示文摘Urban green space(UGS)is essential for sustainable urbanization and human well-being.The utilization status of UGS is closely related to the provision of ecosystem services for urban residents.Limitations on data availability,however,have led to the absence of a comprehensive approach for evaluating the actual utilization status of UGS at a large scale.Furthermore,differences in actual UGS utilization between intra-urban and peri-urban areas have not received enough attention.This study used big data analysis by combining point of interest(POI)and land use and cover change(LUCC)to quantify the spatial patterns of UGS utilization,and to evaluate the actual utilization status of UGS in 366 cities on the Chinese mainland.We also explored the differences in the actual utilization of UGS in intra-urban and peri-urban areas.The results showed that 94.01%of UGS resources in China had not been utilized.There was a clear pattern of spatial mismatch between the stock and the actual utilization of UGS,especially in the north-western region indicated by the Hu Huanyong Line.The actual utilization rate of UGS was closely related to the regional develop-ment level.There was a certain mismatch between the actual utilization and stock of intraurban green space(IUGS).The hot spots of the actual utilization rate of IUGS were in Yunnan,Guizhou,and Sichuan Provinces in southwestern China.The differ-ences in UGS actual utilization rates between IUGS and peri-urban green space(PUGS)were small in eastern China,but large in south-western and northwestern China.The actual utilization rate of IUGS in most Chinese cities was significantly larger than that of PUGS,indicating that PUGS were not well utilized.Our results provide scientific support for urban and regional planners in targeting specific areas for UGS design and development,and in optimizing future UGS planning in China. | Yiyi Huang Tao Lin Guoqin Zhang Yongguan Zhu Zhiwei Zeng Hong Ye | 2021 | Big Earth Data2021，5，3： | 2 |
| 15 | Combined pollution of arsenic and Polymyxin B enhanced arsenic toxicity and enriched ARG abundance in soil and earthworm gut microbiotas显示文摘Polymyxin B(PMB)is considered as the last line of antibiotic defense available to humans.The environmental effects of the combined pollution with PMB and heavy metals and their interaction mechanisms are unclear.We explored the effects of the combined pollution with PMB and arsenic(As)on the microbial composition of the soil and in the earthworm gut,as well as the spread and transmission of antibiotic resistance genes(ARGs).The results showed that,compared with As alone,the combined addition of PMB and As could significantly increase the bioaccumulation factor and toxicity of As in earthworm tissues by 12.1%and 16.0%,respectively.PMB treatment could significantly increase the abundance of Actinobacteria in the earthworm gut(from 35.6%to 45.2%),and As stress could significantly increase the abundance of Proteobacteria(from 19.8%to 56.9%).PMB and As stress both could significantly increase the abundance of ARGs and mobile genetic elements(MGEs),which were positively correlated,indicating that ARGs might be horizontally transferred.The inactivation of antibiotics was the main resistance mechanism that microbes use to resist PMB and As stress.Network analysis showed that PMB and As might have antagonistic effects through competition with multi-drug resistant ARGs.The combined pollution by PMB and As significantly promoted the relative abundance of microbes carrying multi-drug resistant ARGs and MGEs,thereby increasing the risk of transmission of ARGs.This research advances the understanding of the interaction mechanism between antibiotics and heavy metals and provides new theoretical guidance for the environmental risk assessment and combined pollution management. | Lyu Li Dong Zhu Xingyun Yi Jianqiang Su Guilan Duan Xianjin Tang Yongguan Zhu | 2021 | Journal of Environmental Sciences2021，33，11： | 2 |
