在1999年春季和夏季，在欧洲四个不同的地点（荷兰阿姆斯特丹;美国班戈尔; K.的;科英布拉，葡萄牙;弗洛尔斯海姆，德国）。这项研究的目的是建立一个标准化的方法，允许在生态系统一级的化学压力对陆地区划的影响进行调查，并可能使用这些数据在现有的环境风险评估（ERA）的化学品进行评估。这一期的生态毒理学在一系列论文中介绍了TME环测试和现场验证研究的结果。此外，来自一个开放的均匀的陆地微观世界（综合土壤微观世界，ISM）的结果包括在这个系列作为一个单独的文件。在这一系列的第一份文件的背景资料的规划和组织的研究。的概念方法和设计的研究与TMEs的简要概述，在过去25年中，在生态学和应用环境科学的陆地微观世界的使用的科学讨论的基础上。此外，还就选择测量终点以量化陆地生态系统的结构和功能方面提出了一些建议。最后，总结了TME研究的主要结果，并就TME的技术可行性、与实地研究的可比性以及TME在ERA中的潜在用途得出结论。
During spring and summer 1999 a ring-test and field-validation study with an open, intact Terrestrial Model Ecosystem (TME) was conducted at four different European sites ( Amsterdam, The Netherlands; Bangor, U. K.; Coimbra, Portugal; Florsheim, Germany). The objective of the study was to establish a standardised method which allows the impact of chemical stressors on terrestrial compartments at ecosystem level to be investigated and possible uses of such data in existing Environmental Risk Assessments (ERAs) for chemicals to be evaluated. This issue of Ecotoxicology presents in a series of papers the results of the TME ring-test and field-validation study. Additionally, results derived from an open-homogeneous terrestrial microcosm ( Integrated Soil Microcosm, ISM) are included in this series as a separate paper. In this first paper of the series background information on the planning and organisation of the study are given. The conceptual approach and the design of the study with TMEs are briefly outlined, based on the scientific discussion on the use of terrestrial microcosms in ecology and applied environmental sciences during the last 25 years. Further, some suggestions are presented on the selection of measurement endpoints to quantify structural and functional aspects of terrestrial ecosystems. Finally, the main results of the TME-study are summarised and conclusions are drawn on the technical feasibility of TMEs, their comparability with field studies and the potential use of TMEs in ERA.
