AB  - Nanoplastics (NPs) are currently considered an environmental pollutant of 
      concern, but the actual extent of NP pollution in environmental water bodies 
      remains unclear and there is not enough quantitative data to conduct proper risk 
      assessments. In this study, a pretreatment method combining ultrafiltration (UF, 
      100 kDa) with hydrogen peroxide digestion and subsequent detection with pyrolysis 
      gas chromatography-mass spectrometry (Py-GC/MS) was developed and used to 
      identify and quantify six selected NPs in surface water (SW) and groundwater 
      (GW), including poly(vinylchloride) (PVC), poly(methyl methacrylate) (PMMA), 
      polypropylene (PP), polystyrene (PS), polyethylene (PE), and poly(ethylene 
      terephthalate) (PET). The results show that the proposed method could detect NPs 
      in environmental water samples. Nearly all selected NPs could be detected in the 
      surface water at all locations, while PVC, PMMA, PS, and PET NPs were frequently 
      below the detection limit in the groundwater. PP (32.9-69.9%) and PE (21.3-44.3%) 
      NPs were the dominant components in both surface water and groundwater, although 
      there were significant differences in the pollution levels attributed to the 
      filtration efficiency of riverbank, with total mass concentrations of 0.283-0.793 
      mug/L (SW) and 0.021-0.203 mug/L (GW). Overall, this study quantified the NPs in 
      complex aquatic environments for the first time, filling in gaps in our knowledge 
      about NP pollution levels and providing a useful methodology and important 
      reference data for future research.
