To protect the health of human and environment, the European Union implemented the REACH regulation for chemical substances. REACH is an acronym for Registration, Evaluation, Authorization, and Restriction of Chemicals. Under REACH, the authorities have the task of assessing chemical substances, especially those that might pose a risk to human health or environment. The work under REACH is scientifically, technically and procedurally a complex and knowledge-intensive task that is jointly performed by the European Chemicals Agency and member state authorities in Europe. The assessment of substances under REACH conducted in the German Environment Agency is supported by the knowledge-based system KnowSEC, which is used for the screening, documentation, and decision support when working on chemical substances. The software KnowSEC integrates advanced semantic technologies and strong problem solving methods. It allows for the collaborative work on substances in the context of the European REACH regulation. We discuss the applied methods and process models and we report on experiences with the implementation and use of the system.

与KnowSEC合作提供化学安全方面的协作决策支持和文档。

为了保护人类和环境的健康，欧盟对化学物质实施了REACH法规。REACH是化学品注册，评估，授权和限制的首字母缩写。根据REACH，当局的任务是评估化学物质，尤其是那些可能对人类健康或环境构成威胁的化学物质。REACH的工作在科学，技术和程序上都是一项复杂且知识密集的任务，由欧洲化学品管理局和欧洲成员国主管部门共同执行。由德国环境署进行的REACH之下的物质评估得到了基于知识的系统KnowSEC的支持，该系统用于处理化学物质时的筛选，文档编制和决策支持。该软件KnowSEC集成了先进的语义技术和强大的问题解决方法。它允许在欧洲REACH法规的范围内开展物质方面的合作。我们讨论了应用的方法和过程模型，并报告了系统实施和使用的经验。
