绿色液渣是制浆造纸工业的主要废弃物，其正确分类对于寻找填埋处理的替代方案具有重要意义。欧洲联盟正在讨论确定危险特性HP 14（“生态毒性”）的方法。虽然生物测试可能更能代表废物的环境行为，但仍然没有关于程序的官方准则，生态毒性分类依赖于化学成分。本工作旨在评价GLD的生态毒性，以确定HP 14。评估包括化学分析（使用ClassifyMyWaste软件）和一系列针对水生生态系统（Lepidium sativum、Aliivibrio fischeri、Raphidocelis subcapitata、Lemna minor和Daphnia magna）的生物测试。化学分析将GLD列为“可能的危害”，而生物测试表明，五分之三的生物具有高度生态毒性，其中最敏感的是独行菜、浮萍和大型蚤。...
Green liquor dregs (GLD) are a major waste of the pulp and paper industry, and their correct classification is important to finding alternatives to landfill disposal. In the European Union, the methodology to determine the hazard property HP 14 (“ecotoxic”) is under discussion. Although biological tests are likely more representative of wastes’ environmental behavior, there are still no official guidelines on procedures, and ecotoxicity classification relies on the chemical composition. This work aimed to evaluate the ecotoxicity of GLD to determine HP 14. The assessment comprised a chemical analysis (using ClassifyMyWaste software) and a battery of biotests targeting aquatic ecosystems (Lepidium sativum, Aliivibrio fischeri, Raphidocelis subcapitata, Lemna minor, and Daphnia magna). The chemical analysis denoted GLD as a “Possible Hazard,” while the battery of biotests showed high ecotoxic effects for three out of five organisms, the most sensitive being Lepidium sativum, Lemna minor, and Daphnia magna. ...
