| 英文摘要 | Traditional stereomicroscopy (SM) is limited for the identification of microplastics of less than 500 mu m in wastewater treatment plants (WWTPs). Accordingly, novel methods for the accurate quantification of these microplastics are needed. In this study, we investigated the polymer type, morphology, size distribution, and abundance of microplastics in each unit of three selected WWTPs by SM and a fluorescence-based protocol (FR) combined with FTIR. Using the FR method, most microplastics detected in the three WWTPs were 50-200 mu m in size. Polyethylene, polypropylene, and polyamide were the main polymer types, and the distributions of fibers, films, and debris were determined. Despite highly similar microplastic removal rates (78.6-95.2% (SM) and 77.4-94.2% (FR)) in the WWTPs by the two methods, the microplastic abundances obtained by FR (405-6987 items/L) were approximately 2 orders of magnitude higher than the corresponding results by SM (1-21 items/L). In addition, a considerable number of small-sized microplastics (< 500 mu m) were detected in the effluents (405-947 items/L) using FR. These results clearly reveal that microplastics in WWTPs have been seriously underestimated in most previous studies based on SM. Further research should focus on the environmental risks of small-sized microplastics from WWTPs. |
