The abundance and fate of microplastics (MPs) in wastewater treatment plants (WTPs) has been reported extensively. However, in the wastewater, the extent to which hazardous chemicals such as persistent organic pollutants (POPs) accumulated by MPs not been clearly explored. In this study, MPs was sampled from influents and effluents in WTPs to characterize POPs in sorption within MPs. The highest concentrations of PCDD/Fs, PBDD/Fs, PBDEs, and PCBs in sorption within MPs from untreated influents were 5310, 2310, 5,220,000, and 22,700 pg/g, respectively. The most toxic congener, 1,2,3,7,8-PeCDD, accounts for up to 32.3 % of the contribution to PCDD/Fs within MPs. Furthermore, the concentration of PCDD/Fs within MPs from untreated influents could be up to 27.7 times higher than that in microplastic pellets on the coastal beach. This study highlights the quantitative evidence of the POPs within MPs present in untreated influents.

沿海污水处理厂议员对持久性有机污染物的积累
废水处理厂 (WTP) 中微塑料 (MP) 的丰度和归宿已被广泛报道。然而,在废水中,MPs累积的持久性有机污染物(POPs)等有害化学物质的程度尚不清楚。在本研究中,从污水处理厂的进水和出水中取样 MP,以表征 MP 内 POP 的吸附情况。未经处理的进水 MP 中吸附的 PCDD/F、PBDD/F、PBDE 和 PCB 的最高浓度分别为 5310、2310、5,220,000 和 22,700 pg/g。毒性最强的同系物 1,2,3,7,8-PeCDD 占 MP 内 PCDD/F 的贡献高达 32.3%。此外,未经处理的进水中的 MP 中的 PCDD/F 浓度可能比沿海海滩上的微塑料颗粒中的浓度高出 27.7 倍。这项研究强调了未经处理的进水中 MP 中存在 POP 的定量证据。
