摘要

由天然物质组成的产品的再利用和再循环相对来说没有明显的环境问题。然而,利用现代合成技术生产的产品的回收利用往往带来新的挑战。我们的分析表明,用人工物质乙二胺四乙酸取代柠檬酸会造成严重的环境问题。在易北河流域进行的案例研究表明,乙二胺四乙酸浓度超标,特别是伏尔塔瓦河和易北河汇合处的浓度超标。提出了未来技术发展和环境政策的开放性问题和任务,特别是以自然物质取代人工物质的想法。这将有助于在资源利用中更好地引入循环经济理念。

Persistent water pollutants: case of ethylenediaminetetraacetic acid in the Czech Republic
Reuse and recycling of products composed of natural matter is relatively without significant environmental problems. However, recycling of products produced using modern synthetic technologies often brings new challenges. Our analysis has shown that substitution of citric acid with artificial substance of ethylenediaminetetraacetic acid causes important environmental problems. The case study carried out in the Elbe river basin shows that the ethylenediaminetetraacetic acid concentration standard has been exceeded, particularly from confluence of the Vltava and Elbe rivers. Open questions and tasks for future technological development and environmental policies are formulated, particularly the idea to replace artificial substances with nature-based ones. This would enable better introduction of circular economy ideas in the use of resources.
