学术报告预告 // 南水北调流域生态安全讲座第21

----德国科学院院士Andreas Schäffer教授学术报告


报告时间:2025年10月21日(周二)下午14:30-15:00

报告地点:南阳师范学院中区科技楼一楼报告厅


报告一

报告题目:The dialectics of zero pollution plans and expanding chemical productivity(零污染计划与化学生产力扩张的辩证关系)

报 告 人:德国科学院院士Andreas Schäffer教授,亚琛工业大学环境研究所前所长

报告摘要:在全球范围内,雄心勃勃的“零污染”计划正成为环境政策的核心目标,旨在彻底消除化学物质对自然生态和人类健康的风险。然而,与此同时,全球化学品的产量和多样性仍在持续快速增长,以满足社会发展的需求。这一矛盾构成了本次讲座的核心议题。

   Andreas Schaeffer教授将基于其数十年在环境化学、污染物代谢及生态风险评估领域的深入研究,深入剖析这一深刻的辩证关系。讲座将探讨,在追求“零污染”的宏伟目标下,我们当前的科学认知与技术能力所面临的极限。例如,化学品的“非提取残留物”问题——这些残留物在环境中无法被常规方法检测与分析,但其结构与生物有效性信息至关重要——正是实现精准风险评估与真正“零污染”的巨大挑战。

   另一方面,化学工业生产力的扩张不仅带来了已知化学品的数量增长,更持续引入新的物质(如纳米材料)和复杂的转化产物,这使得环境监测与评估任务变得空前复杂。谢弗教授将论证,单纯的“末端治理”或“零排放”口号,在复杂的现实环境系统和经济增长需求面前,可能是不充分的,甚至会产生误导。

   本讲座旨在引发一场批判性思考:我们如何才能在可持续化学管理的框架下,协调这两个看似对立的目标?Schaeffer教授将提出,未来的道路不在于追求一个绝对无化学风险的乌托邦,而在于发展更智能的化学设计、建立基于整体生态系统健康的评估体系、以及推动一场关于化学品“绿色解毒”技术的创新。最终,实现从线性污染向循环生态的转型,才是解决这一辩证矛盾的关键。

报告人简介:

Andreas Schäffer was trained as chemist and finished his PhD-thesis in 1984. He worked as postdoctoral fellow at Harvard University, Boston/USA, and at the University of Zürich, Switzerland, in the field of bio-inorganic chemistry. From 1989-1997 he worked as researcher in an agrochemical company. Afterwards he became professor for Environmental Biology and Chemodynamics at the technical University of Aachen (RWTH Aachen). His research interests relate to the metabolism of organic xenobiotics, such as pesticides and other chemicals and nano-materials in soil, water and sediments, plants and other organisms. One focus of research are non-extractable residues of chemicals usually lacking information on structure and bioavailability. Another area of interest is testing the effects of pollutants on the communities of terrestrial and aquatic organisms.

Since 2003 he is in addition director of the Research Institute for Environmental Analysis and Assessment, gaiac, in Aachen/Germany (www.gaiac. rwth-aachen.de), a spin-off company of the university group. In 2012 and 2014 he became adjunct and honorary professor at Nanjing and Chongqing universities, respectively. He served as expert for the environmental risk assessment of chemicals in national and international panels. He has published more than 200 papers, and three text books.

Schäffer教授的大学教育经历始于德国明斯特大学,在完成本科至博士学习后,先后在美国哈佛大学、瑞士苏黎世大学开展博士后研究工作。随后,他进入瑞士巴塞尔Ciba-Geigy/Novartis(瑞士诺华)工作近十年(1989-1997)。随后他回归学术界,于1997年至今担任德国亚琛工业大学环境研究所所长,弗朗霍夫分子生物学和应用生态学研究所所长(第二职位)。并且从2002年至今,担任生态系统分析和评估研究所(gaiac)所长,开展“产-学-研”相融合的工作。

Schäffer教授自2015-至今,遴选为德国国家科学院(National Academy of Sciences Leopoldina)环境委员会成员(院士)。2019年开始担任化学污染国际专家组委员(International Panel on Chemical Pollution, IPCP),该专家组目前负责组建联合国环境规划署(UNEP)化学品与废物管理政府间框架组织设置(2025年3月正式设置成立)。此外,他曾任欧洲食品安全局(EFSA)农药残留评估专家,德国化学学会主席,德国联邦风险评估管理局(BfR)专家,德国联邦消费者保护和食品安全办公室专家。《Environmental Science and Pollution Research》编委、《Soils》编委、《Environmental Science: Advances》编委。

在他的带领下,亚琛工业大学环境生态领域成为全球最为重要的研究机构之一。Schäffer教授与中国专家学者有长期的接触和交流合作。2009年,Schäffer教授开始与重庆大学专家教授合作,并联合德国知名高校和研究机构,与中国重庆大学、同济大学、南京大学等高校,在德国教育与研究部(BMBF)长江项目(the Yangtze Project)的资助下,对长江生态环境保护开展联合研究。其中,Schäffer教授所在的亚琛工业大学与重庆大学结成重要合作伙伴,致力于三峡库区生态保护研究和学生培养。2012年他受聘成为南京大学共同教授,随后于2014年获得重庆大学荣誉教授称号。

报告二

报告题目:Research progress on the eco-environment of the Three Gorgeous Reservoir(三峡库区生态环境研究进展)

报 告 人:重庆大学环境与生态学院 陈忠礼教授

报告摘要:

世界上最大的水电工程三峡水库的建设和运行,给区域生态环境带来了深刻的变化。本报告综合了过去二十年来在理解这些影响方面取得的广泛研究进展。虽然该项目在防洪、发电和航运方面取得了显著效益,但也带来了一系列复杂的环境挑战。主要研究结果强调了水质的重大变化,包括营养富集和水文稳定导致的支流湾反复发生藻华。一个关键的新问题是对“三峡水库生态环境网络”(GREEN)的重大影响,包括水生生态系统的生物多样性丧失、波动带的土壤侵蚀以及沉积物中污染物的积累。最近的研究侧重于通过优化大坝运行、水位波动区的生态恢复和流域管理实践等措施来监测、建模和减轻这些影响。本综述的结论是,未来的研究必须优先考虑流域综合管理、长期生态预测和制定适应性策略,以确保三峡库区生态环境的长期健康和可持续性。

The construction and operation of the Three Gorges Reservoir (TGR), the world's largest hydropower project, have brought profound changes to its regional eco-environment. This presentation synthesizes the extensive research progress made in understanding these impacts over the past two decades. While the project has yielded significant benefits in flood control, power generation, and navigation, it has also induced a complex set of environmental challenges. Key research findings highlight major shifts in water quality, including recurrent algal blooms in tributary bays driven by nutrient enrichment and hydrological stabilization. A critical emerging issue is the significant impact on the "Gorges Reservoir Eco-environment Network" (GREEN), encompassing biodiversity loss in aquatic ecosystems, soil erosion in the fluctuating zone, and the accumulation of pollutants in sediments. Recent research has focused on monitoring, modeling, and mitigating these effects through measures such as optimized dam operation, ecological restoration of the water-level fluctuation zone, and watershed management practices. This review concludes that future research must prioritize integrated basin management, long-term ecological forecasting, and the development of adaptive strategies to ensure the long-term health and sustainability of the TGR's eco-environment.
