- Abstract:
- Microplastics (MPs) are defined as plastic smaller than 5 mm in diameter. As an emerging pollutant derived from the human daily life and industry activities, it has been widely detected in ecosystem. MPs are considered to be from the personal care and cosmetic product, synthetic fibers during washing, and urban rainwater off. Wastewater treatment plants (WWTPs) play a special role in the mass flow of MPs because it is not only one of the important point sources of MPs released into environment, but also a way of collecting and removing MPs from wastewater. During the wastewater treatment process, the manner and characteristics of the MPs have also changed. However, the standard analytical methods of MPs have not been established in worldwide. This review summarizes the updated studies of MPs behavior in WWTPs, which include sampling, sample pretreatment and MPs identification and characterization. Emphasis was placed on various MPs analyzing methodologies in the literature. The removal effect of MPs in WWTPs was also briefly summarized. Furthermore, the existing problems and future perspectives were discussed.
