AB  - Riparian areas are highly dynamic bio-geophysical settings with a surge of waste 
      deposition predominantly including land-based plastic discards. These polymer 
      discards are destined to be the prime constitution of marine "plastisphere." The 
      polymer fate is determined by waterbodies, where the chances of plastic retention 
      are higher, eventually mediating the formation of microplastics (MPs) in years or 
      decades. Such formed MPs are a potential threat to the aqua bio-regime. A 
      systematic investigation of three waterbody basin soils (Karamana River, 
      Killiyar, and Akkulam-Veli Lake) showed the presence of MPs in all the samples 
      analyzed with varying sizes, shapes, colors, and compositions. MPs of the shapes 
      flakes, fragments, filaments, sheets, foams, and fibers were observed with 
      dimensions 0.3-4.7 mm. Most of the particles were white in hue (WT), followed by 
      colorless (CL), light yellow (L.Y), light brown (L.B), orange (OR), red (RD), and 
      blue (BL), respectively. The polymer communities were identified as high-density 
      polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), 
      polyethylene terephthalate (PET), polystyrene (PS), and nylon. The highest 
      average MP density was identified in the basin of Killiyar (799 +/- 0.09 pieces/kg) 
      followed by Karamana River (671 +/- 3.45 pieces/kg), indicating the closeness of 
      the sampling station to the city center compared to Akkulam-Veli Lake 
      (486 +/- 58.55 pieces/kg). The majority of the sampling sites belonged to the slopy 
      areas and came under the highly urbanized land category. A close association was 
      observed between particle abundance and urban activity. The study foresees 
      possible threats inflicted by MP abundance upon the area-wide hydro-biological 
      system.
