摘要

调查了黄河一级支流无定河上游干流和纳林河、海流兔河、榆溪河、芦河等支流水体微塑料的丰度和分布情况.结果显示：无定河上游流域水体微塑料的平均丰度为15.58n/L，范围2.5~35.63n/L.微塑料类型丰富，占比依次为PEG（62.96%）、PE（6.17%）、PPS（3.09%）、4-vinylbiphenyl（2.78%）、PCTG（2.47%）、PS（2.16%）、PTFE（2.16%）、PPSU（1.85%）、PMMA（1.54%）、其他（14.81%）.超过96%的微塑料小于1mm，极易进入生物体富集.形状以碎片为主，其次是薄膜和颗粒状；大部分为透明或棕色，其他颜色占比约25%.基于微塑料的源特定分类体系，初步判定微塑料主要来源于农用地膜、个人洗护用品.结果表明无定河上游流域水体微塑料整体处于轻度污染水平.有毒有害塑料的滥用尤为需要引起关注.无定河上游流域位于毛乌素沙漠东南部的风沙滩地，其微塑料研究一方面揭示了风沙滩地水体微塑料的赋存现状和潜在污染风险；另一方面提供了一个典型案例，即以微塑料的视角，科学认识沙漠地区的城市发展和农业生产对水体环境的影响.

Abstract

In this study, We investigated the abundance and distribution of microplastics in the upper main stream of the Wuding River, a first-order tributary of the Yellow River, and the tributaries of the Nalin River, the Hailiu Rabbit River, the Yuxi River and the Lu River. The results showed that:The average abundance of microplastics in the water bodies of the upper Wuding River Basin was 15.58n/L, ranging from 2.5 to 35.63n/L. Microplastic types were abundant, with the percentages of PEG (62.96%), PE (6.17%), PPS (3.09%), 4-vinylbiphenyl (2.78%), PCTG (2.47%), PS (2.16%), PTFE (2.16%), PPSU (1.85%), PMMA (1.54%), others (14.81%). More than 96% of the microplastics were less than 1mm, which was very easy to enter the enrichment of organisms. The shape is dominated by fragments, followed by films and granules; most of them were transparent or brown, and other colors accounted for about 25%. Based on the source-specific classification system of microplastics, it was initially determined that microplastics mainly originated from agricultural mulch film and personal toiletries. The results indicate that the overall risk of microplastics in water bodies in the upper watershed of the Wuding River was at a mild pollution level. The abuse of toxic and harmful plastics was of particular concern. The study of microplastics in the upper Wuding River basin, which is located in the windy beach area in the southeastern part of the Mawusu Desert, on the one hand reveals the current status and potential pollution risk of microplastics in the windy beach area; on the other hand, it provides a typical case of scientific understanding of the impact of urban development and agricultural production on the water environment in the desert area from the perspective of microplastics.
