| 1 | Bioavailability of crops to environmental hormone Pb in soils and its remediation显示文摘Lead (Pb), as an environmental hormone, acts as an estrogen in animal and human bodies, and its envi- ronmental pollution can result in many procreant anomalies, such as maladjustment of incretion, weakening of pro- creation function and descending of genital immunity. Experiments on pot-growth of paddies and corns in this study indicated that these crops did not show any macro-toxic symptoms in the observed contents of Pb added (0–4000 mg/kg) in soils. However, lead in soils can be easily absorbed by crops and accumulated in the different parts of plants. Statistical analysis showed that Pb contents in the crops are strongly positively correlated to the Pb contents in soils. In the crops, the Pb contents of roots are highest, tens to thousands of times those of straws and seeds. It is suggested that the root is a barrier of Pb absorbed by straws and seeds. Based on this fact, Pb pollution in soils can be gradually reduced by planting crops and subsequently removing the roots from the soil. This biotechnology may be used in environmental remediation, which embraces the quality of sustainable agricultural economy and a healthy environment. | KUANG Shaoping SONG Feng | 2008 | Chinese Journal Of Geochemistry2008，27，1： | 4 |
| 2 | Discovery of Wolitu Pb-Zn deposit through geochemical prospecting under loess cover in Inner Mongolia, China显示文摘We report the finding of the Wolitu Pb-Zn deposit in Inner Mongolia, China, through a series of geochemical surveys. The Wolitu area, located in the loess-cover area in the Hure Banner, Tongliao City,Inner Mongolia, and neighboring the Horqin Sandy Land to the north, had no previous history of Pb-Zn mining or record of Pb-Zn mineralization. Our study identified a large Pb-Zn anomaly with potential zones of mineralization by stream sediment survey. Random rock sampling reveals limonitization at sporadic outcrops in the gullies. The high concentrations of Pb in the residual debris provided guidelines to fix the position for exploratory trench. Oxidized concealed orebodies were identified by trenching.Blind orebodies in veins hosted within the structural zone between slates and marbles of the upper Carboniferous Shizuizi Formation and the Permian granite were discovered by drilling. It is computed that the ore reserve may reach up to 540,000 tones with Pb grade of 1.27% and Zn of 1.9%. This case study is an excellent example for identifying potential polymetallic deposits in loess covered terrains using geochemical exploration. | Fan Yang Mu Kong Huazhong Liu Jinsong Yu Shaoping Yang Zhihong Hao Dehui Zhang Kuang Cen | 2017 | Geoscience Frontiers2017，8，5： | 3 |
| 3 | Pollution characteristics of polycyclic aromatic hydrocarbons (PAHs) in oily sludge from the Zhongyuan Oilfield and its peripheral soils显示文摘The purpose of this study is to determine the degree of contamination caused by polycyclic aromatic hydrocarbons (PAHs) in oily sludge and soils around it in the Zhongyuan Oilfield. The contents of polycyclic aro-matic hydrocarbons in oily sludge samples were determined with HPLC. The contents of PAHs of oily sludge from three different oil production plants vary from high to low in the order of the Wenming oily sludge dumping site of No. 3 Oil Production Plant (3W)>the Mazhai oily sludge dumping site of No. 3 Oil Production Plant (3M)>the Wen'er oily sludge dumping site of No. 4 Oil Production Plant (4W). Naphthalene, acenaphthylene, acenaphthene, fluorine and phenanthrene are the major pollutants of PAHs in oily sludge. The contents of PAHs in soil samples around the oily sludge dumping sites vary widely from 434.49 to 2408.8 ng/g. Naphthalene, acenaphthene, fluorine, phenanthrene and pyrene are the characteristic factors of PAHs in soil samples of 3M and 3W, and naphthalene, acenaphthene, fluorine and phenanthrene are the characteristic factors of PAHs in soil samples of 4W. According to these data and the ratios of Fl/Py, PAHs in oily sludge samples come mainly from petrogenic sources, and soil samples are divided into petrogenic soil samples and mixed-source soil samples, and both petrogenic and pyrogenic soil samples in terms of the sources of PAHs. The classification by Nemero index P indicates that soils around the oily sludge dumping sites have been seriously polluted. | KUANG Shaoping XU Zhong | 2009 | Chinese Journal Of Geochemistry2009，28，2： | 3 |
| 4 | Tectonic affinity of Paleozoic stratigraphic slices along the northern margin in Dabie Orogen,central China: evidence from Pb isotope of rocks显示文摘Metavolcanic and metasedimentary rocks from the Paleozoic tectono-stratigraphic units along the northern margin in the Dabie orogen show that there are two types of Pb isotopic compositions, which have some affined regularity with tectonic subdivision. Compared with the main tectonic units of the Qinling orogen, the Dingyuan Formation should be the part of the South Qinling orogenic belt or the northern margin of the Yangtze craton, characterized by less radiogenic Pb isotopic composition, and the Guishan Formation, Nanwan Formation-Foziling Group and the Carboniferous should be the part of the North Qinling orogenic belt which is extended to the east, characterized by more radiogenic Pb isotopic composition. These facts combined with the distribution of the geological units suggest that the Paleozoic subduction zone between the Yangtze and North China cratons should be located in the north boundary of the Nanwan Formation-Foziling Group or somewhere that is covered by the Nanwan Formation-Foziling Group now. From the Pb isotopic evidence and suggestion presented here, one aspect of the constraint is provided for determining the position of the Triassic collision suture between the two cratons. | XU Qidong, OUYANG Jianping, ZHANG Benren and KUANG Shaoping(1.

| 5 | Uptake, accumulation and translocation of polycyclic aromatic hydrocarbons by winter wheat cultured on oily sludge-amended soil显示文摘The purpose of this study is to comparatively investigate the plant uptake, accumulation and translocation behaviors of polycyclic aromatic hydrocarbons (PAHs) as priority pollutants in soil contaminated with oily sludge. The influence of different oily sludge application doses on the uptake of contaminants was studied together with the profile of individual PAH in roots, straws and leaves of winter wheat. Pot experiments were conducted using oily sludge application doses of 0, 5, 10, 15 and 20 percent, respectively. The total PAHs contents of control soil and oily sludge were 16.96 and 3504.66 μg/g, respectively. Analysis for the contents of the 16 PAHs was carried out with a HPLC-UV using plant tissue samples obtained at the 265th day of growth. The total PAHs contents in treated winter wheat were 9.02-334.81 ng/g for roots, 8.45-336.52 ng/g for straws and 10.70-406.32 ng/g for leaves. In addition to 5% of oily sludge dose, the total PAHs content in leaves was always highest under other doses of oily sludge application. With respect to individual PAH, the content did not show a significant plant tissue related trend. However, both the total content and individual content of PAHs in treated winter wheat tissues did increase with increasing oily sludge application dose. Another analysis for the control soil indicates that the degradation rate of PAHs was significantly enhanced by winter wheat after 265 days of growth based on the residual concentrations of PAHs in planted and unplanted soils. | YU Wenjuan KUANG Shaoping ZHAO Laishi | 2013 | Chinese Journal Of Geochemistry2013，32，3： | 2 |

| 9 | Dissipation of polycyclic aromatic hydrocarbons in crop soils amended with oily sludge显示文摘Oil fields present a potential ecological risk to nearby farmland soil. Here we present a new method designed to evaluate the ability of winter wheat(Triticum aestivum) to contribute to the dissipation of polycyclic aromatic hydrocarbons(PAHs), which are priority pollutants in soils contaminated by oily sludge. The influence of different doses of oily sludge on the dissipation of PAHs was studied along with individual PAH profiles in soils after different periods of plant growth. Five soil samples were artificially contaminated with different percentages of oily sludge(0 %, 5 %, 10 %, 15 % and 20 %). Winter wheat grew in the oily sludge–amended soils for 265 days.PAH content in the soils was monitored over the course of the study. The rate of PAH dissipation is related to the properties of different PAHs, period of winter wheat growth, and oily sludge application dose. Analysis for treated soils indicates that the dissipation of PAHs increased significantly over the first 212 days, followed by minimal changes over the final 53 days of treatment. In contrast, PAH dissipation slowed with increasing oily sludge application. For each PAH, the experimental results showed a significant compound-dependent trend. Winter wheat in the present study significantly enhanced the dissipation of PAHs in oily sludge–contaminated soil. | Shaoping Kuang Wenjuan Yu Yan Song Yaqing Su Huihui Wang Lina Wang | 2016 | Acta Geochimica2016，35，4： | 1 |
| 10 | Accelerated biogenic silica dissolution by marine invertebrate digestion:in comparison with phosphorus and iron显示文摘Herbivore digestion in aquatic ecosystems is usually considered a method of nutrient repackaging rather than recycling,as recalcitrant and low-level nutrients are presumed for their egesta.We hypothesize that this opinion holds only for nutrients recycled by excretion and egestion,not for those elements recycled overwhelmingly by fecal decomposition.In this study,we compared the dissolution of biogenic silica(BSi),phosphorus(P)and iron(Fe)between two food items and fecal pellets of two marine invertebrates fed on artificial seawaters free of bacteria.Relative to raw food materials,the mass proportion in fecal pellets of BSi increased,while that of P and Fe decreased.During the 21 days of incubation,the total dissolution rate of BSi was 13.9–36.0 times higher in fecal pellets than food items,followed by P(1.5–4.2 times)and Fe(1.1–2.4 times).While the dissolution of BSi and Fe occurred mostly in the first few days,P was mostly released in the last ten days.Regarding BSi dissolution,a higher rate was observed in oyster Crassostrea gigas than the Echiuran Urechis unicinctus,but no significant difference was found between fecal pellets in either species under naturally available diatom food(Phaeodactylum tricornutum)and introduced terrestrial food(rice husk powder),respectively.Our results show direct evidence of digestion-associated nutrients mobilization.BSi dissolution after animal digestion may be similarly efficient to that caused by bacteria colonization in natural seawater. | Ying WANG Shaoping KUANG Guangtao ZHANG | 2022 | Journal of Oceanology and Limnology2022，40，3： | 0 |
