Characterization of interaction between different adsorbents and copper by simulation experiments using sediment-extractedorganic matter from Taihu Lake, China

Yan ZHANG,Yuan ZHANG,Tao YU

《环境科学与工程前沿（英文）》 2014年第8卷第4期页码 510-518 doi: 10.1007/s11783-013-0588-y

摘要： The complex capacity of different types of organic matters (OMs) for Cu was quantitatively studied by simulation experiments using different adsorbents prepared from the sediment in Taihu Lake. The free Cu was measured with ion selective electrode (ISE) and complex capacity was calculated using a conditional formation constant model. The result indicated that the complex capacity was 0.048 mmol·g , 0.009 and 0.005 mmol·g for raw sediment, sediment without DOM, sediment without insoluble organic matters but with DOM and sediment without OM. Insoluble organic matter played a major role in the sorption of Cu in sediment and it can adsorb most Cu from water column. In the solution, Cu mainly existed as a complex with DOM and the DOM-Cu complexation capacity was 327.87 mg·g . The change of TOC and pH indicated ion-exchange in the interaction between free Cu and DOM. When the Cu concentration in the experiment reached the complex capacity of DOM, precipitation was the major mechanism to remove Cu from water phase, which was observed from UV absorbance change of DOM, that is, its aromaticity increased while molecular weight decreased. The desorption result indicated that DOM was more capable of desorbing Cu from adsorbents without OM than adsorbent with OM. The desorbed quantity with DOM was 1.65, 1.78 and 2.25 times higher than that with water for adsorbents without OM, raw adsorbents (sediment) and adsorbents without DOM.

Phosphorus release potential and pollution characteristics of sediment in downstream Nansi Lake, China

Zhijian LI, Qinyan YUE, Baoyu GAO, Yanwen WANG, Qing LIU

《环境科学与工程前沿（英文）》 2012年第6卷第2期页码 162-170 doi: 10.1007/s11783-011-0313-7

摘要： The research aimed to evaluate present and potential phosphorous pollution due to high sedimentary phosphorus load and release from sediment, when external phosphorus was reduced in downstream Nansi Lake. Pollution load of the sediment and overlying water was investigated. Kinetics and isotherms of adsorption/release of sedimentary phosphorus were studied to determine equilibrium phosphate concentration (EPC ) and release potential. Kinetics of phosphorus adsorption on sediment and release from sediment were well described by both the pseudo-first-order rate equation and the pseudo-second-order rate equation, but more appropriate to the pseudo-second-order rate equation with the adsorption/release capacity more close to the measured values, suggesting that the processes were chemically rate controlled and dependent on adsorption capacity. Soluble reactive phosphorus (SRP) sorption isotherms on sediment were best fitted by the modified Langmuir model indicating a monolayer adsorption. By comparing EPC and SRP of water, the status (adsorption, releasing or in equilibrium) of sediment phosphorus could be determined. The sediments at site S1, S3, S4, S5, and S7 where the EPC s were greater than the SRPs, had a potential to release phosphorus into the water column. However, those sediments at S9, S10, and S12, where the EPC s were approximately equal to the SRPs, were in impermanent equilibrium with overlying water in status of phosphorus, the sediments can be likely to release phosphorus to the water column once the equilibrium was broken. Therefore, sedimentary phosphorus can be a secondary pollution source in downstream Nansi Lake.

Quantitative characterization of Cu binding potential of dissolved organic matter (DOM) in sediment fromTaihu Lake using multiple techniques

Yuan ZHANG,Yan ZHANG,Tao YU

《环境科学与工程前沿（英文）》 2014年第8卷第5期页码 666-674 doi: 10.1007/s11783-013-0608-y

摘要： Dissolved organic matter (DOM) plays an important role in heavy metal speciation and distribution in the aquatic environment especially for eutrophic lakes which have higher DOM concentration. Taihu Lake is the third largest freshwater and a high eutrophic lake in the downstream of the Yangtze River, China. In the lake, frequent breakout of algae blooms greatly increased the concentration of different organic matters in the lake sediment. In this study, sediment samples were collected from various part of Taihu Lake to explore the spatial difference in the binding potential of DOM with Cu. The titration experiment was adopted to quantitatively characterize the interaction between Cu(II) and DOM extracted from Taihu Lake sediments using ion selective electrode (ISE) and fluorescence quenching technology. The ISE results showed that the exogenous DOM had higher binding ability than endogenous DOM, and DOM derived from aquatic macrophytes had a higher binding ability than that derived from algae. The fluorescence quenching results indicated that humic substances played a key role in the complexation between DOM and Cu(II) in the lake. However, because of the frequent breakout of algae blooms, protein-like matters are also main component like humic matters in Taihu Lake. Therefore, the metals bound by protein-like substances should be caused concern as protein-like substances in DOM were unstable and they will release bound metal when decomposed.

《环境科学与工程前沿（英文）》 2020年第14卷第4期 doi: 10.1007/s11783-020-1245-x

摘要： Abstract • The total organic pollutant concentrations in sediment were 27.4-1620 ng/g. • The phenol concentrations were relatively high in the sediment of the Dianchi Lake. • Average total concentrations decreased as follows: Caohai>Waihai>Haigeng Dam. • 1,4-dichlorobenzene, 3- or 4-methylphenol, 1,2,4-trichlorobenzene might be risks. Organic pollutants are widespread environmental pollutants with high toxicity, persistence, and bioaccumulation. Our aim was to investigate the distribution of aromatic amines, phenols, chlorobenzenes, and naphthalenes in the surface sediment of the Dianchi Lake, China. Nineteen surface sediment samples were collected from the Dianchi Lake, and 40 types of organic pollutants were analyzed via gas chromatography–mass spectrometry. The total organic pollutant concentrations in the surface sediment of the Dianchi Lake varied from 27.4 to 1.62 × 103 ng/g. The concentrations of phenols were much higher than those in other water bodies but still within a controllable range, whereas the concentrations of the other organic pollutant classes were similar or even lower. The detection ratio of 3- or 4-methylphenol was the highest (100.00%) among the pollutants. The average total organic pollutant concentrations decreased in the following order: Caohai (540 ng/g)>the middle of Waihai (488 ng/g)>the edge of Waihai (351 ng/g)>Haigeng Dam (90.4 ng/g). Pearson analysis showed a strong correlation among 1-methylnaphthalene, 2-methylnaphthalene, 1,3-dinitronaphthalene, and 1,4-dinitronaphthalene (p<0.01). Caohai, the north lakeshore of Waihai and the south of Waihai showed higher risk because of high concentration; meanwhile, 1,4-dichlorobenzene, 3- or 4-methylphenol and 1,2,4-trichlorobenzene were more likely to cause risks.

摘要： Through the use of general sampling and measurement by Cs dating, problems regarding the absence of monitoring data can easily be resolved. Further, weighted values need to be determined while Environment Quality Comprehensive Index (EQCI) is commonly used as applied in environmental quality comprehensive evaluation. In order to overcome the subjectivity in determining weights, the modified Analytical Hierarchy Process (AHP) method was designed. The modified AHP method involved the following key procedures: First, the parameters and were calculated based on the monitoring data; second, the factors were put in order according to the symbol and value of and ; third, the continuous odd integers, which represented the importance of factors, were given to factors according to their seating order; and, fourth, the factor weights were determined from the pair-wise comparison matrix calculated by the ratio of the given odd integers. Therefore, the weights were completely based on the monitoring data. In the present study, the comprehensive quality of sediments in five sections of Lake Dianchi were evaluated and the results indicated that the current contamination of sediments in each lake section is much more serious than at any other time in history.

《环境科学与工程前沿（英文）》 2014年第8卷第6期页码 905-921 doi: 10.1007/s11783-014-0650-4

摘要： Variations of phosphorus (P) and its species in surface sediment of Baiyangdian Lake, a eutrophic shallow lake located in North China, were investigated through combination of field survey and numerical calculation based on cluster analysis. P fractionation was performed by a sequential extraction scheme, categorized as loosely bound P (NH Cl-P), reductant soluble P (BD-P), metallic oxide bound P (NaOH-P), calcium bound P (HCl-P) and organic P (Org-P). P concentrations exhibited regional similarities and a total of four sub-areas were identified in which the same rank was HCl-P>Org-P>BD-P ≈ NaOH-P>NH Cl-P. NH Cl-P, BD-P and Org-P were found to contribute to P enrichment in overlying water column. Specifically, labile Org-P acted as a potential pool with a greater contribution in aerobic layer compared to anaerobic layer. A hysteresis (lag= 4 months) existed when labile Org-P concentration was negatively correlated with aerobic layer thickness. In view of magnitude of identified P contributors in sub-areas, higher potential of P release was present in Fuhe River and Tang River estuary areas. On the basis of calibration and verification, the mathematical model with parameter settings applied in this study was improved to serve as a tool for limnology management and eutrophic control.

摘要：

汞（Hg）及其衍生物作为危险的环境污染物，其生物毒性、生物累积和放大作用对水生生态系统和人类健康造成潜在风险。沉积物柱芯可为湖泊历史污染过程提供重要信息，追溯人类活动或自然条件变化的影响。本研究以浅水富营养化湖泊——巢湖为例，解析巢湖沉积物中汞的百年历史变化及其受人类活动和气候变化的影响。结果表明，巢湖汞的沉积经历了3个阶段（20世纪60年代前、20世纪60—80年代和20世纪80年代后）。20世纪60年代前，沉积物柱芯汞含量的变化趋势不显著，且东、西湖区无空间差异；20世纪60—80年代，沉积物汞的浓度逐渐升高，西湖区的汞浓度高于东湖区，主要与西湖区受人为污染较重有关；通过分析沉积物汞与重金属（铁、钴、铬、铜、锰、铅、锌）、碳氮稳定同位素（δ¹³C 和 δ¹⁵N）、营养物质、粒度和气象因子的关系，揭示了人类活动、水动力条件和气候变化对巢湖汞沉积的影响，发现20 世纪60年代以后沉积物剖面的汞浓度明显升高，主要是由于水动力条件变化和流域经济快速发展导致了人为源汞输入的增长。此外，温度、风速和蒸发量对汞的环境行为和归趋产生交互复杂影响。

摘要：

昭阳湖是韩国最大的湖泊，与江原道的春川市、杨口郡和麟蹄郡接壤。作为环境资源，昭阳湖被广泛用于水电、防洪和供水。为此，本文调查了昭阳湖洪滩区，并对该地区的沉积物进行了分析。文中利用GPS数据和航空摄影技术监测了昭阳湖洪滩区的沉积物。为了确保采样位置测量的准确性，我们比较了来自三个GPS单元的数据。在三个地点采集了沉积物样本：两个地点在洪滩区的东部平原地区；一个地点在西部地区。总共收集了8个样本：其中在东部采样点采集了三个样本，采集深度以每10 cm的间隔采集到30 cm的深度。在西部采样点采集了两个样本，采集深度分别为10 cm和30 cm。收集样品后分析了颗粒大小和含水量的垂直趋势和水平趋势。沉积物样品的大小从粗粒到极粗粒，呈负斜率趋势分布，这表明溃口有东移的趋势。洪滩区东侧的含水量高，有发生溃口的可能性，且东侧发生溃口的概率比西侧高。这项研究结果表明，通过对颗粒细度、含水量、泥沙沉积量和泥沙去除率的分析，可以了解和预测昭阳湖的溃口运动方向和泥沙分布情况。

《环境科学与工程前沿（英文）》 2013年第7卷第6期页码 851-859 doi: 10.1007/s11783-013-0569-1

摘要： The aim of this study was to investigate the benthic bacterial communities in different depths of an urban river sediment accumulated with high concentrations of nutrients and metals. Vertical distributions of bacterial operational taxonomic units (OTUs) and chemical parameters (nutrients: , , dissolved organic carbon, and acid volatile sulfur; metals: Fe, Zn, and Cu) were characterized in 30 cm sediment cores. The bacterial OTUs were measured using the terminal restriction fragment length polymorphism analysis. Biodiversity indexes and multivariate statistical analyses were used to characterize the spatial distributions of microbial diversity in response to the environmental parameters. Results showed that concentrations of the nutrients and metals in this river sediment were higher than those in similar studies. Furthermore, high microbial richness and diversity appeared in the sediment. The diversity did not vary obviously in the whole sediment profile. The change of the diversity indexes and the affiliations of the OTUs showed that the top layer had different bacterial community structure from deeper layers due to the hydrological disturbance and redox change in the surface sediment. The dominant bacterial OTUs ubiquitously existed in the deeper sediment layers (5–27 cm) corresponding to the distributions of the nutrients and metals. With much higher diversity than the dominant OTUs, the minor bacterial assemblages varied with depths, which might be affected by the sedimentation process and the environmental competition pressure.
