摘要:
全球水环境中的微塑料污染日益引起人们的关注。针对江南水乡22条小型淡水河流，研究了微塑料（粒径<5 mm）的丰度、粒径、颜色和形状分布，调查了微塑料污染水平。研究发现，微塑料丰度为3.50~12.00 个/L；就颜色而言，黑色微塑料占比最高，达到30.79%，高于蓝色（28.57%）、无色（21.59%）和红色（19.05%）；就形状来说，纤维占比最高，达到85.40%，高于颗粒（5.40%）、薄膜（3.80%）和碎片（5.40%）。微塑料粒径主要集中在30～40 μm，占比为26.25%。可见，苏州古城区22条河流均不同程度地受到微塑料污染。这为进一步了解内陆淡水生态系统中的微塑料变化规律，以及制定相应的污染防控措施提供了有力支撑。
Abstract:
The microplastic pollution in the global water environment has attracted increasing attention. Microplastics in the surface water samples collected from 22 slow?flowing water in Suzhou, a typical southern water town, were investigated. It was found that the abundance of microplastics reached 3.50-12.00 items/L. All of the plastics collected were categorized according to shape, color and size. Black (30.79%) was the dominant polymer; blue, transparent and red microplastics accounted for 28.57%, 21.59% and 19.05%, respectively. Fiber (85.40%) was the most abundant type; particles, films and fragments accounted for 5.40%, 3.80% and 5.40%, respectively. The particle size of microplastics was mainly concentrated in 30-40 μm, accounting for 26.25%. The results suggest that different levels of microplastic pollution occurres in slow?flowing surface water which can provide valuable references for further understanding of microplastic pollution in inland freshwater ecosystems.
