3南京某钢铁公司周边耕作土壤的磁学性质与重金属污染的相关性研究显示文摘对取自于南京西南郊某钢铁公司附近水稻田土壤NJ008样芯进行了磁性测量和重金属含量分析,探讨了利用农业耕作土壤的磁参数指示工业区周围重金属污染的可行性.环境磁学测试结果表明:磁化率(χ)、非磁滞剩磁(ARM)及饱和等温剩磁(SIRM)在土壤剖面上部20cm显著增强,磁化率平均值达到112.5×10?8m3·kg?1;20cm以下呈现为较低磁背景特征,磁化率平均值为27.8×10?8m3·kg?1.进一步的磁学实验证明低矫顽力的亚铁磁矿物主导了NJ008样芯的磁性特征,不完整反铁磁性矿物在20cm以下土壤中含量相对较高.Ni,Cu,Fe,Pb,V和Zn等重金属与磁化率呈现相同的变化特征.主成分分析表明亚铁磁性矿物和重金属受同一主成分控制,且磁指标(χ,ARM和SIRM)与重金属(Ni,Cu,Fe,Pb,V和Zn)呈显著相关关系(0.69≤R≤0.98).对远离钢铁公司的同种耕作土壤剖面NJ013测试表明:其磁化率随深度变化不大,绝对值与NJ008在20cm以下磁背景值基本一致.表明耕作过程中的化肥和农药对土壤磁化率影响不大,钢铁公司释放的工业污染是NJ008土壤剖面中磁化率显著增强的主要原因.耕作土壤由于反复翻种,虽然不能用于污染历史及污染物迁移过程研究,但基于磁指标与部分重金属之间的显著相关性,耕作土壤仍然可以用于重金属污染分布范围的圈定和相对污染程度评价.段雪梅 胡守云 闫海涛 Blaha U.

4北京首钢工业区大气重金属污染树叶的磁学响应显示文摘在北京西郊首钢工业区及附近混杂的居民区、公园绿地和农村耕作区采集了55个一年生的树叶样品,并对其进行岩石磁学和元素含量分析.结果表明:磁性矿物的含量和粒径由污染源区向周边递减.研究区域树叶的磁性由低矫顽力的磁铁矿主导.进一步研究表明样品的主要磁性参数(磁化率、非磁滞剩磁以及饱和等温剩磁)与元素Fe,Pb,Cr,V和Zn呈显著相关关系(0.73≤R≤0.88).因此树叶的磁参数可以作为大气重金属污染研究的理想替代指标.胡守云 段雪梅 沈明洁 Blaha U Rosler W 闫海涛 Appel E Hoffmann V 2008科学通报2008,53,4:19
5Environmental magnetic studies of lacustrine sediments显示文摘In recent decades, environmental magnetism has become an important method for studying past global climatic and environmental changes. For an environmental magnetic study, it is important to understand the magnetic properties of various magnetic minerals in lacustrine sediments and the processes involved in the formation, transport, and preservation of these magnetic minerals. The magnetic response of lacustrine sediments to climatic change may vary widely from lake to lake. To reconstruct the processes contributing to paleoclimatic and paleoenvironmental change, it is, therefore, necessary to derive a complete understanding of the potential origin of the magnetic signal observed.HU Shouyun, DENG Chenglong, E.

6Environmental mechanism of magnetic susceptibility changes of lacustrine sediments from Lake Hulun, China显示文摘The changes of magnetic susceptibility (κ) are correlated with those of corresponding sedimentological, geochemical, mineralogical and biological results, which verifies that κ can be taken as one of the environmental proxies. However, usually the exact origin of magnetic signal is poorly understood, and is difficult to relate with the environmental evolution. Magnetic properties of material derived from the catchment and sedimentary environment may affect the accumulation, preservation, or authigenesis and diagenesis of magnetic minerals. In the Lake Hulun region in Inner Mongolia, it is found that muddy sediments, deposited during high water level period (corresponding to humid climate), have comparatively high κ values. In contrast, the sandy sediments, deposited during low water level period (corresponding to arid climate), have low κ values. Detailed rock magnetic investigation confirms that detrital magnetite derived from volcanic rocks in the catchment exists in both muddy and sandy胡守云 王苏民 Erwin Appel 吉磊 2000Science China Earth Sciences2000,43,5:16
7DEVELOPMENT OF COMMON WHEAT GERM-PLASM RESISTANT TO BARLEY YELLOW DWARF VIRUS BY BIOTECHNOLOGY显示文摘Barley yellow dwarf virus (BYDV) is one of the most serious wheat diseases in China. So far no resistance has been described in common wheat. A certain level of BYDV resistance was found in thirteen Triticeae species. Thinopyrum intermedium, two octoploids derived from TH. intermedium/wheat, Zhong 4 awnless and TAF46, and one disomic addition line, L1 derived from TAF46, showed good resistance to BYDV by enzyme linked immunosorbent assay (ELISA). Two wheat/TA. intermedium translocation lines, CPI 119880 and CPI 119899, showing good BYDV resistance were developed from L1 by using both CSph mutant and tissue culture. It is found that their BYDV resistance was controlled by a single dominant gene. Two cDNA probes pEleAcc3 and pPJN8 (E1-T1) were screened for detecting Th. intermedium DNA in wheat background. A specific band for the DNA of Th. intermedium and its derivatives was found in Southern hybridization. It is also possible to determine the size of the alien segment by comparing the relative density辛志勇 徐惠君 陈孝 林志珊 周广和 钱幼亭 成卓敏 P. J. LARKIN P. BANKS R. APPELS B. GLARKE AND R. I. S.

9临汾市树叶磁性的时空变化特征及其对大气重金属污染的指示显示文摘粉煤灰经工厂废气排放进入大气,对人类健康和生态系统都造成了无法弥补的破坏.本文选取具有高空间分辨率优势的树叶作为收集粉煤灰的载体,对临汾市大气中可吸入颗粒物进行磁学参数和重金属含量监测.结果表明,磁化率最大值出现在工厂污染源附近,磁化率空间分布呈现随污染源距离增加而降低的趋势.工业区收集到的磁性颗粒以低矫顽力、粗粒度的磁铁矿为主.夏季磁性矿物来源单一,主要为人为影响.冬季大气中悬浮的磁性颗粒有部分来自于西北风/北风的自然尘降.同一采样点磁化率随时间变化特征表明,树叶的磁学性质可以灵敏和有效地反映较短时期内大气污染的现状.统计分析表明磁化率和重金属元素(铁,铬,镍,铜,铅,钴)之间存在显著相关性.污染负荷指数用于评估研究区域内重金属各元素综合污染的程度.结果显示,在废弃的旧工业区附近无大气污染指示,但在运营中的工厂集中的地区,大气均受到严重污染.污染负荷指数与表征磁性矿物含量的磁化率呈相关性(r2=0.66),因此树叶的磁性参数可以作为大气重金属污染的替代指标.曹丽婉 胡守云 Appel Erwin 师尚礼 尹刚 2016地球物理学报2016,59,5:12
10Relationship between magnetic parameters and heavy element contents of arable soil around a steel company,Nanjing显示文摘Magnetic parameters and element contents were determined in core NJ008 collected from the uppermost ca. 40 cm in a steel company in southwest Nanjing. The results showed that magnetic susceptibility (χ), saturation isothermal remanent magnetization (SIRM) and anhysteretic remanent magnetization (ARM) were enhanced in the uppermost 20 cm, with a mean magnetic susceptibility value of 112.5×10-8 m3 kg-1. Below 20 cm, χ decreased sharply with a mean value of 27.8×10-8m3 kg-1. Low-coercivity minerals such as magnetite dominate in arable soils, while the relative content of antiferromagnetic minerals increases below 20 cm. Heavy metals (Ni, Cu, Fe, Pb, V, and Zn) have similar vertical trends as χ. Principal component analysis reveals common high loadings of the same factor for magnetic concentration parameters (χ, ARM, and SIRM) and elements (Ni, Cu, Fe, Pb, V, and Zn) with an excellent linear correlation (0.69≤R≤0.98) between them. Magnetic susceptibility of paddy soil core NJ013, which had the same parent material as NJ008 but was far from pollution sources, showed stable values of magnetic concentration parameters along the whole core. Absolute values correspond to the so-called magnetic background value (below 20 cm) of NJ008. This indicates that pesticide and fertilizer had little effect on magnetic signals of the upper part of core NJ008 and the extremely enhanced magnetic concentration parameters originate from the steel company emission. Although, the arable soil does not reveal the pollution history and transportation due to annual ploughing, the significant linear relationship between magnetic concentration parameters and heavy metal contents suggests that magnetic parameters can serve as a proxy for quickly detecting soil metallic pollution and estimating the extent of contamination.BLAHA U ROESLER W APPEL E 2010Science China Earth Sciences2010,53,3:10
11Magnetic response to atmospheric heavy metal pollution recorded by dust-loaded leaves in Shougang industrial area, western Beijing显示文摘Fifty-five evergreen tree's leaves growing less than one year were collected from Shougang industrial area in western suburb of Beijing, including steel plants and its ambient residential areas, recreational parks and farmlands. Rock magnetic properties and heavy metal contents were studied. The results show that the magnetic properties of leaf samples are predominated by low-coercivity magnetite, and both the concentration and grain size of magnetite particles gradually decreased with the distance from the main pollution source increases. Moreover, there is a significant linear relationship between magnetic parameters (the low-field magnetic susceptibility, saturation isothermal remanent magnetization and anhysteretic remanent magnetization) and heavy metals contents (Fe, Pb, V, Cr and Zn) (0.73≤R≤ 0.88). Hence, the magnetic parameters of leaves can serve as a proxy for quick detecting of the recent atmospheric metallic pollution.HU ShouYun DUAN XueMei SHEN MingJie U BLAHA W ROESLER YAN HaiTao E APPEL V HOFFMANN 2008Chinese Science Bulletin2008,53,10:10
12Resequencing of 145 Landmark Cultivars Reveals Asymmetric Sub-genome Selection and Strong Founder Genotype Effects on Wheat Breeding in China显示文摘Controlled pedigrees and the multi-decade timescale of national crop plant breeding programs offer a unique experimental context for examining how selection affects plant genomes.More than 3000 wheat cultivars have been registered,released,and documented since 1949 in China.In this study,a set of 145 elite cultivars selected from historical points of wheat breeding in China were re-sequenced.A total of 43.75 Tb of sequence data were generated with an average read depth of 17.94x for each cultivar,and more than 60.92 million SNPs and 2.54 million InDels were captured,based on the Chinese Spring RefSeq genome v1.0.Seventy years of breeder-driven selection led to dramatic changes in grain yield and related phenotypes,with distinct genomic regions and phenotypes tar-geted by different breeders across the decades.There are very clear instances illustrating how introduced Italian and otherforeign germplasm was integrated into Chinese wheat programs and reshaped the genomic landscape of local modern cultivars.Importantly,the resequencing data also highlighted significant asymmetric breeding selec-tion among the three sub-genomes:this was evident in both the collinear blocks for homeologous chromosomes and among sets of three homeologous genes.Accumulation of more newly assembled genes in newer cultivars implied the potential value of these genes in breeding.Conserved and extended sharing of linkage disequilibrium(LD)blocks was highlighted among pedigree-related cultivars,in which fewer haplotype differences were detected.Fixation or replacement of haplotypes from founder genotypes after generations of breeding was related to their breeding value.Based on the haplotype frequency changes in LD blocks of pedigree-related cultivars,we propose a strategy for evaluating the breeding value of any given line on the basis of the accumulation(pyramiding)of bene-ficial haplotypes.Collectively,our study demonstrates the influence of 'founder genotypes' on the output of breeding efforts over many decades and also suggests that founder genotype perspectives are in fact more dy-namic when applied in the context of modern genomics-informed breeding.Chenyang Hao Chengzhi Jiao Jian Hou Tian Li Hongxia Liu Yuquan Wang Jun Zheng Hong Liu Zhihong Bi Fengfeng Xu Jing Zhao Lin Ma Yamei Wang Uzma Majeed Xu Liu Rudi Appels Marco Maccaferri Roberto Tuberosa Hongfeng Lu Xueyong Zhang 2020Molecular Plant2020,13,12:9
13The enhanced element enrichment in the supercritical states of granite–pegmatite systems显示文摘In this paper, we show that supercritical fluids have a greater significance in the generation of pegmatites,and for ore-forming processes related to granites than is usually assumed. We show that the supercritical melt or fluid is a silicate phase in which volatiles; principally H_2O are completely miscible in all proportions at magmatic temperatures and pressures. This phase evolves from felsic melts and changes into hydrothermal fluids, and its unique properties are particularly important in sequestering and concentrating low abundance elements, such as metals. In our past research, we have focused on processes observed at upper crustal levels, however extensive work by us and other researchers have demonstrated that supercritical melt/fluids should be abundant in melting zones at deep-crustal levels too. We propose that these fluids may provide a connecting link between lower and upper crustal magmas,and a highly efficient transport mechanism for usually melt incompatible elements. In this paper, we explore the unique features of this fluid which allow the partitioning of variouselements and compounds, potentially up to extreme levels,and may explain various features both of mineralization and the magmas that produced them.Rainer Thomas Paul Davidson Karen Appel 2019Acta Geochimica2019,38,3:8
14钠摄入量与血压的关系随能量摄入而变化:终止高血压膳食研究-钠试验的二次分析显示文摘膳食钠的摄入量是以绝对量(mg/d)表示而不是以钠密度(mg/kcal)表示的。研究者旨在确定钠摄入量与血压关系的强弱是否随着能量摄入量而变化。终止高血压膳食研究(dietary approaches to stop hypertension,DASH)-钠试验是比较2种膳食(DASH和对照)和3种钠密度水平的随机膳食摄入试验。刘青 叶鹏 Murtaugh MA Beasley JM Appel LJ Guenther PM McFadden M Greene T Tooze JA 2018中华高血压杂志2018,26,6:7
15南海南部YSJD-86GC孔沉积物磁性特征及其环境意义显示文摘选取位于南海南部的YSJD-86GC(简称86GC)孔沉积物柱状样进行环境磁学研究,结合已发表的年代框架,揭示MIS3阶段以来沉积物的磁学变化特征.岩石磁学结果表明钻孔沉积物以低矫顽力的磁铁矿类矿物为主要携磁矿物,同时存在部分赤铁矿.反映磁性颗粒大小的King图和Day图表明沉积物中磁性矿物以细粒伪单畴为主.磁学参数与地球化学指标剖面变化的对比分析表明86GC孔沉积物磁性特征反映的是陆源物质的信息;研究钻孔沉积物的磁学性质同时受陆源物质输入量、物源区的氧化-还原条件及搬运环境和距离等多种因素共同影响.全球气候变化引起的海平面升降是导致研究钻孔沉积物中磁性矿物含量和磁性颗粒大小变化的主要原因,沉积物磁学性质的变化可间接指示本地区的海平面升降.欧阳婷萍 田成静 朱照宇 邱燕 APPEL Erwin 付淑清 2014科学通报2014,59,19:6
16Magnetic Properties of Tree Leaves and Their Significance in Atmospheric Particle Pollution in Linfen City,China显示文摘Fifty-one tree leaves were sampled in the industrial area,residential area,and Fenhe River ecological zone,for the purpose of a magnetic study on atmospheric pollution in Linfen City,Shanxi Province,China.Measurements of mass-specific magnetic susceptibility(χ) show a significant variation range(from 11.6 × 10-8 m3/kg to 129.7 × 10-8 m3/kg).Overall values of magnetic susceptibility decline in the following sequence:industrial area > residential area > Fenhe River ecological zone.The relatively elevated concentration-related magnetic parameters(saturation isothermal remanent magnetization,anhysteretic remanent magnetization and magnetic susceptibility) appear in the industrial area,with their highest values in the vicinity of Linfen Steel Mill.Magnetic particles are dominated by multidomain,magnetite-like minerals.Magnetic particle concentration and grain size both decrease with the increasing distance from industrial area,indicating the industrial area,especially Linfen Steel Mill,is the main source of atmospheric particle pollution.Residential area and Fenhe River ecological zone are also affected by industrial emission to a certain extent.The results of this study indicate that magnetic measurements of tree leaves are practicable for monitoring and determination of atmospheric pollution in Linfen City.YIN Gang HU Shouyun CAO Liwan Wolfgang ROESLER Erwin APPEL 2013Chinese Geographical Science2013,23,1:6
