In the precent study, the microplastics (MPs) pollution level was evaluated in diverse environmental samples from the Yellow River Delta. The results indicated that the abundance of MPs in water, sediment and soil samples ranged from 0.50 to 7.83 items·L, 200 to 4200 items·kg, and 100 to 1400 items·kg, respectively. Film form of MPs was dominant in water, while fiber MPs were dominant in both sediment and soil samples. In all samples, most MPs were < 1 mm in size. White was the main color in water, black was the main color in sediment and soil samples. The most common MPs type was polyethylene (33 %) in water, while rayon accounted for the majority of MPs in sediment (42 %) and soil (70 %) samples. The redundancy analysis results showed that MPs in water and sediment were more affected by water quality, while soil MPs were easily affected by landscape pattern.
在本研究中，评估了黄河三角洲多种环境样本中的微塑料（MPs）污染水平。结果表明，水样、沉积物和土壤样本中 MPs 的丰度范围分别为 0.50 至 7.83 个·L、200 至 4200 个·kg 和 100 至 1400 个·kg。 MPs 以薄膜形式为主，在水和沉积物中纤维状 MPs 占主导地位，而在土壤中则以碎片形式为主。所有样本中，大多数 MPs 的尺寸都<1mm。水样中以白色为主，沉积物和土壤样本中以黑色为主。水样中最常见的 MPs 类型是聚乙烯（33%），而在沉积物（42%）和土壤（70%）样本中，人造纤维占主导地位。冗余分析结果表明，水样和沉积物中的 MPs 更多地受到水质的影响，而土壤中的 MPs 则更容易受到景观格局的影响。
