改进收集技术对于开发有效且经济可行的解决方案来从河流环境中捕获塑料至关重要。然而，世界各地的河流中都在建造和部署浮动栅栏，但并未对其有效性进行严格测试。在本研究中，我们测试了吊杆在现实条件下多种配置和处理方式（包括“C 形”和“斜线形”配置）的有效性。为此，我们使用了从废物管理渠道泄漏的相同大塑料，以尽可能真实。我们总共使用了 13 种不同聚合物的 52 种塑料制品。在这种情况下，所测试的 C 型吊杆的整体有效性低于预期（约 37% 的保留率）。斜线形吊臂的效果相当差（
Improving collection technologies is crucial to develop effective and economically feasible solutions for catching plastic from riverine environments. However, floating booms are being constructed and deployed in river around the world without rigorously testing its effectiveness. In this study, we tested the effectiveness of a boom under realistic conditions for several configurations and treatments (including "C-shape" and "Slash-shape" configurations). For this, we used the same macroplastics that leak out of waste management channels in order to be as realistic as possible. In total we used 52 plastic articles of 13 different polymers. The global effectiveness of the tested C-shape boom was lower than expected under such conditions (around 37 % of retention). The effectiveness of the Slash-shape boom was considerably worst (
