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, with a mean abundance of 27.84 ± 11.81 particles L. 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.
本研究首次对上海七个小型河口的微塑料污染水平进行了评估。微塑料的丰度范围为 13.53±4.6 至 44.93±9.41 个/L，平均值为 27.84±11.81 个/L。从样品中收集的微塑料分为四类（纤维、薄膜、颗粒和碎片），颗粒是最丰富的类型。高达 99.5%的微塑料直径小于 2 毫米。微塑料有多种颜色，黑色是占主导地位的颜色。验证的微塑料主要类型为聚丙烯（37.5%）和聚乙烯（50%）。我们的研究表明，小型河口存在严重的微塑料污染，相关河流急需关注微塑料污染防治。
