在资源、环境和经济协调发展的大背景下,发展绿色矿业已成为国家战略重点推进并得到了广泛认同。大型资源基地绿色调查及环境评价指标体系的建立、模型的技术实现将为解决生态脆弱区找矿部署与环境保护瓶颈问题发挥重要作用。本文将绿色调查与环境评价两方面工作有机结合,分四个层次构建指标框架,通过3S技术提取生态环境现状及变化信息,结合连续三年的地表水、土壤等多环境介质野外调查取样分析数据,对经过验证的、成熟的评价方法进行优化,运用更兼容、可扩展的Python语言编程建立了基于支持向量机的大型锂资源基地环境评价模型。运用该模型,将大型基地环境现状划分为环境较差区、环境一般区、环境较好区、环境良好区四类区域,总体准确率达97.77%。结果表明,本文建立的该套有针对性的评价指标体系能够对川西大型锂资源基地的环境现状作出有效的评价,通过技术创新实现了大型锂资源基地环境现状“像元级”可视化分级,较客观地反映了甲基卡矿区及周边资源开发环境问题与影响范围,在一定程度上可辅助规范大型基地矿产资源开发利用的管理及决策。

Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the *** of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and *** approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.

底泥在表面流人工湿地污染物迁移转化中起到非常重要的载体作用,探究其营养盐的累积特征与释放规律对了解长期运行的表流湿地净化功能具有重要意义.以运行了5 a的盐龙湖表面流人工湿地底泥为研究对象,对不同位置底泥的总有机碳(TOC)、总氮(TN)和总磷(TP)含量进行分析并开展柱状芯样静态释放实验.结果表明,盐龙湖表流湿地运行5 a后,底泥整体属于中度污染范畴,营养盐累积水平主要受进水条件、水深和植物作用等影响.(1)顺着水流方向,表流湿地底泥营养盐含量表现升高趋势;(2)随着上覆水水深增大,底泥营养盐含量升高,碳受影响程度较深;(3)表流湿地植物的生长情况越好,底泥中累积的营养盐含量也越高.底泥营养盐释放趋势呈现为先升后降,在20 d后基本达到平衡.释放速率主要受湿地底泥营养盐累积水平影响,其规律与轻度营养型水库底泥较为相似.表流湿地底泥中包含的植物残体会使营养盐释放更强烈,研究结果可为长期运行的表面流人工湿地提升净化能力提供科学依据.

探地雷达是探测地下结构及其分布规律的一种重要的浅层地球物理探测方法,具有分辨率高、无损、抗干扰能力强、结果直观等优点,在工程物探领域被广泛应用。为提高对地下管线雷达图像特征的认识,确定管线异常体的位置,提高地质雷达的解释精度,利用时域有限差分法(FDTD)对地下管线进行精细化探测,包括对管线埋深、材质、管线内充填物、管线病害等影响因素的数值模拟,以此建立地下管线正演模拟合成图库,进而指导探地雷达实际探测图像的解释工作。现场管线探测结果表明:探地雷达可准确探测出地下管线的埋设位置及运行状态,为今后的维修养护提供了依据。

锂能源金属的战略地位不断提高,与锂矿床及锂金属相关的研究也在不断跟进,锂矿区土壤重金属污染近年来持续受到关注,其含量分布情况值得深入研究。本文对亚洲最大的锂矿区--川西甲基卡根系土壤环境进行重金属含量监测,调查和评价锂矿区土壤重金属含量水平及其安全性。2016-2018年于川西甲基卡锂资源富集区采集根系土壤样品68件,采用电感耦合等离子体质谱法(ICP-MS)测定根系土壤Cd、As、Pb、Cr、Cu、Ni、Zn含量。测试结果表明,甲基卡矿区根系土壤Cd、As、Pb、Cr、Cu、Ni、Zn含量平均值分别为0.13、15.31、25.47、60.57、16.12、23.59、66.83mg/kg,与2018年8月最新颁布的农用地土壤标准对比,无一超标,均低于风险筛选值及管制值。常见矿床的尾矿库区土壤一般存在严重的重金属污染,而甲基卡尾矿库土壤重金属含量均低于环境标准限值,且矿业活动停止的三年期间尾矿库区根系土壤中Cd、As、Cr含量明显呈逐年下降趋势。本研究认为,选矿厂房及尾矿库周边根系土壤重金属由于人为源的存在有一定的富集现象,但不构成危害,废弃物对环境污染小。

Background:A One Health approach has been increasingly mainstreamed by the international community, as it provides for holistic thinking in recognizing the close links and inter-dependence of the health of humans, animals and the environment. However, the dearth of real-world evidence has hampered application of a One Health approach in shaping policies and practice. This study proposes the development of a potential evaluation tool for One Health performance, in order to contribute to the scientific measurement of One Health approach and the identification of gaps where One Health capacity building is most urgently ***:We describe five steps towards a global One Health index (GOHI), including (i) framework formulation;(ii) indicator selection;(iii) database building;(iv) weight determination;and (v) GOHI scores calculation. A cell-like framework for GOHI is proposed, which comprises an external drivers index (EDI), an intrinsic drivers index (IDI) and a core drivers index (CDI). We construct the indicator scheme for GOHI based on this framework after multiple rounds of panel discussions with our expert advisory committee. A fuzzy analytical hierarchy process is adopted to determine the weights for each of the ***:The weighted indicator scheme of GOHI comprises three first-level indicators, 13 second-level indicators, and 57 third-level indicators. According to the pilot analysis based on the data from more than 200 countries/territories the GOHI scores overall are far from ideal (the highest score of 65.0 out of a maximum score of 100), and we found considerable variations among different countries/territories (31.8–65.0). The results from the pilot analysis are consistent with the results from a literature review, which suggests that a GOHI as a potential tool for the assessment of One Health performance might be ***:GOHI—subject to rigorous validation—would represent the world’s first evaluation tool that constructs the
