Abstract

Stormwater is recognised as a vector for microplastics (MPs), including tyre wear particles (TWPs) from land-based sources to receiving waterbodies. Before reaching the waterbodies, the stormwater may be treated. In this study, sediments from six treatment facilities (five retention ponds and a subsurface sedimentation tank) were analysed to understand MP occurrence, concentrations, sizes, polymer types and distribution between inlet and outlet. The concentrations of MPs showed large variations between and within different facilities with MP concentrations of 1,440-72,209 items/kg (analysed by μFTIR) corresponding to 120-2,950 μg/kg and TWP concentrations from

雨水截留池沉积物中包括轮胎磨损颗粒在内的微塑料的组成和浓度。

雨水被认为是微塑料（MPs）的载体，包括从陆地来源到接收水体的轮胎磨损颗粒（twp）。在到达水体之前，雨水可能会被处理。在这项研究中，分析了来自六个处理设施（五个保留池和一个地下沉淀池）的沉积物，以了解MP的发生、浓度、大小、聚合物类型以及入口和出口之间的分布。不同设施之间和内部的多磺酸盐浓度差异较大，多磺酸盐浓度为1,440-72,209项/kg （μFTIR分析），对应于120-2,950 μg/kg
