This study involved an assessment of the levels of microplastic pollution in seven small-scale estuaries in Shanghai for the first time. The abundance of microplastics ranged from 13.53 +/- 4.6 to 44.93 +/- 9.41 particles L-1, with a mean abundance of 27.84 +/- 11.81 particles L-1. Microplastics collected from samples were classified into four types (fiber, film, granule, and fragment), and granules were the most abundant type. Up to 99.5% of microplastics were < 2 mm in diameter. The microplastics had a variety of colors, with black being the dominant color. Polypropylene (37.5%) and polyethylene (50%) were the main types of microplastic component validated. Our study showed severe microplastic pollution in small-scale estuaries, and the associated rivers need urgent attention for microplastic pollution prevention.
