| 1 | Soil heavy metal pollution from Pb/Zn smelting regions in China and the remediation potential of biomineralization显示文摘Smelting activities pose serious environmental problems due to the local and regional heavy metal pollution in soils they cause. It is therefore important to understand the pollution situation and its source in the contaminated soils. In this paper, data on heavy metal pollution in soils resulting from Pb/Zn smelting(published in the last 10 years) in China was summarized. The heavy metal pollution was analyzed from a macroscopic point of view. The results indicated that Pb, Zn, As and Cd were common contaminants that were present in soils with extremely high concentrations. Because of the extreme carcinogenicity, genotoxicity and neurotoxicity that heavy metals pose, remediation of the soils contaminated by smelting is urgently required. The primary anthropogenic activities contributing to soil pollution in smelting areas and the progressive development of accurate source identification were performed. Due to the advantages of biominerals, the potential of biomineralization for heavy metal contaminated soils was introduced. Furthermore, the prospects of geochemical fraction analysis, combined source identification methods as well as several optimization methods for biomineralization are presented, to provide a reference for pollution investigation and remediation in smelting contaminated soils in the future. | Xinghua Luo Chuan Wu Yongcheng Lin Waichin Li Min Deng Jingqiang Tan Shengguo Xue | 2023 | Journal of Environmental Sciences2023，，3： | 5 |
| 2 | A practical method for identifying key factors in the distribution and formation of heavy metal pollution at a smelting site显示文摘Smelting activities are the main pathway for the anthropogenic release of heavy metals(HMs)into the soil-groundwater environment.It is vital to identify the factors affecting HMs pollution to better prevent and manage soil pollution.The present study conducted a comprehensive investigation of HMs in soil from a large abandoned Zn smelting site.An integrated approach was proposed to classify and quantify the factors affecting HMs pollution in the site.Besides,the quantitative relationship between hydrogeological characteristics,pollution transmission pathways,smelting activities and HMs pollutionwas established.Results showed that the soils were highly contaminated by HMs with a pollution index trend of As>Zn>Cd>Pb>Hg.In identifying the pollution hotspots,we conclude that the pollution hotspots of Pb,As,Cd,and Hg present a concentrated distribution pattern.Geo-detector method results showed that the dominant driving factors for HMs distribution and accumulation were the potential pollution source and soil permeability.Additionally,the main drivers are variable for different HMs,and the interaction among factors also enhanced soil HMs contamination.Our analysis illustrates how the confounding influences from complex environmental factors can be distilled to identify key factors in pollution formation to guide future remediation strategies. | Jiaqing Zeng Wenshun Ke Min Deng Jingqiang Tan Chuxuan Li Yizhi Cheng Shengguo Xue | 2023 | Journal of Environmental Sciences2023，，5： | 3 |
| 3 | Application of high-speed counter-current chromatography coupled with high performance liquid chromatography for the separation and purification of Quercetin-3-O-sambubioside from the leaves of Nelumbo nucifera显示文摘Quercetin-3-O-sambubioside[Quercetin-3-O-β-D-xylopyranosyl(1→2)-β-D-glucopyranoside]was separated and purified by semi-preparative high-speed counter-current chromatography(HSCCC)with a twophase-solvent system composed of ethyl acetate-nbutanol-water(4∶1∶5,v/v)from the leaves of Nelumbo nucifera(Lotus).A total of 5.0 mg of the targeted compound with a purity of 98.6%as determined by high performance liquid chromatography(HPLC)was obtained from 100 mg of the crude extract cleaned up by AB-8 macroporous resin in a one-step separation.Quercetin-3-O-sambubioside was a novel flavonoid glycoside from the leaves of Nelumbo nucifera,and its chemical structure was identified by means of ESI-MS,1D NMR and 2D NMR. | Shengguo DENG Zeyuan DENG Yawei FAN Jing LI Rong LIU Dongmei XIONG | 2009 | Frontiers of Chemical Science and Engineering2009，3，4： | 1 |
