Photographs of typical microplastics collected from the sampling sites. The photos are corresponding to (a) fragment; (b) fiber; (c) pellet; (d) film; (e) < 250 μm, from the 0–4 cm layer of the NTH; (f) 250–500 μm, from the 12–16 cm layer of the NTH; (g) 500–1000 μm, from the 20–25 cm layer of the SWTH; and (h) 1000–5000 μm, from the 4–8 cm layer of the SWTH. The sands in the microscopic domains were separated from the sediment
