Abstract
- 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.<br />Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2024 Elsevier Ltd.
