Microplastics have pulled the alarm for its far-reaching impacts in the environment and potential risks to human health. Here, we first investigated the microplastic pollution in the Zhangjiang River of southeastern China. Water samples were collected across a river catchment using bulk sampling method. The abundance, distribution, and characteristics of microplastics were analyzed using stereomicroscopy and micro-Raman spectroscopy. The results indicated that microplastic abundance ranged from 50 to 725 items m with an average of 246 items m. PP and PE were the major polymers and accounted for ~75%. The dominant shape, color, and size of microplastics are fragment, white, and 0.5-1 mm, respectively. The findings established the baseline information on the microplastic pollution in the Zhangjiang River, which may improve the knowledge of sources of microplastic debris to the local watershed and future evaluation on the role of river catchments in transporting microplastics to the estuary and beyond into the ocean.
微塑料因其在环境中的深远影响及其对人类健康的潜在风险而发出警报。在这里，我们首次调查了中国东南部的张江河水体中的微塑料污染。使用批量采样法在整个河流流域收集水样。使用立体显微镜和微拉曼光谱法分析微塑料的丰度、分布和特征。结果表明，微塑料丰度范围为 50 至 725 个/立方米，平均为 246 个/立方米。PP 和 PE 是主要的聚合物，约占 75%。微塑料的主要形状、颜色和尺寸分别为碎片、白色和 0.5-1 毫米。这些发现为张江河水体中的微塑料污染建立了基线信息，这可能有助于提高对当地流域微塑料碎片来源的认识，并为未来评估河流流域在将微塑料输送到河口及更远的海洋中的作用提供依据。
