The production of toxic plant secondary metabolites (phytotoxins) for defense is a widespread phenomenon in the plant kingdom and is even present in agricultural crops. These phytotoxins may have similar characteristics to anthropogenic micropollutants in terms of persistence and toxicity. However, they are only rarely included in environmental risk assessments, partly because a systematic overview of phytotoxins is missing. Here, we present a newly developed, freely available database, Toxic Plants-PhytoToxins (TPPT), containing 1586 phytotoxins of potential ecotoxicological relevance in Central Europe linked to 844 plant species. Our database summarizes phytotoxin patterns in plant species and provides detailed biological and chemical information as well as in silico estimated properties. Using the database, we evaluated phytotoxins regarding occurrence, approximated from the frequencies of Swiss plant species; environmental behavior based on aquatic persistence and mobility; and toxicity. The assessment showed that over 34% of all phytotoxins are potential aquatic micropollutants and should be included in environmental investigations.
植物次生代谢物（植物毒素）的产生是植物界中一种广泛存在的防御现象，甚至在农业作物中也存在。这些植物毒素在持久性和毒性方面可能与人为的微污染物具有相似的特征。然而，它们在环境风险评估中很少被包括在内，部分原因是缺乏对植物毒素的系统概述。在这里，我们提出了一个新开发的、免费提供的数据库，即 Toxic Plants-PhytoToxins（TPPT），其中包含了与中欧 844 种植物物种相关的 1586 种具有潜在生态毒理学相关性的植物毒素。我们的数据库总结了植物物种中的植物毒素模式，并提供了详细的生物和化学信息以及通过计算机估算的性质。我们使用该数据库评估了植物毒素的存在情况，这是根据瑞士植物物种的频率近似估算的；基于水生持久性和流动性的环境行为；以及毒性。评估表明，超过 34%的所有植物毒素都是潜在的水生微污染物，应该包含在环境调查中。
