    摘要:

    微塑料污染(microplastics pollution)在全球范围内受到广泛关注。相比于海洋环境以及其他主要河流、湖泊的微塑料污染情况,黄河流域的相关数据较为贫乏。通过综述文献分析了黄河流域河道沉积物和表层水的微塑料污染丰度、类型以及空间分布特征,探讨了黄河流域重要城市和重点保护区的微塑料污染现状,并提出了相应的防控措施。结果表明:黄河流域沉积物和表层水中微塑料污染在空间分布上整体呈现自上游向下游增多的趋势,尤其在黄河三角洲湿地该趋势更加明显;黄河流域沉积物和表层水中微塑料类型存在明显差异,主要与微塑料的材质有关;与全国同类区域相比,黄河流域国家重点城市市域和国家湿地公园的微塑料污染水平处于中高程度,应引起重视;塑料通过多种暴露途径会对黄河滩区养殖业和人类健康造成严重影响。控制黄河流域水体微塑料污染,需要完善相关生产标准和法律法规,提高可降解微塑料产能和塑料废弃物的工程化降解能力。

    Abstract:

    Microplastics pollution has attracted worldwide attention. Compared with the status quo of microplastics pollution in marine environment and other major rivers and lakes, the relevant data of the Yellow River basin is relatively inadequate. The abundance, types, and spatial distribution characteristics of microplastic pollution in the sediments and surface water of the Yellow River basin were reviewed. Meanwhile, the status of microplastic pollution in the national central city and Yellow River Delta wetland was discussed, and the corresponding prevention and control measures were put forward. The results showed that the spatial distribution of microplastics pollution in sediments and surface water of the Yellow River basin increased from upstream to downstream, especially in the Yellow River Delta wetland. There are obvious differences between the types of microplastics in sediment and surface water in the Yellow River basin, which is mainly related to the materials of microplastics. Compared with similar regions in China, the microplastics pollution levels in national key cities and national wetland parks in the Yellow River basin are in the medium to high degree, which should be taken seriously. Plastics exposure through various ways will cause serious impact on aquaculture and human health in the Yellow River beach area. To control microplastic pollution in the Yellow River basin, it is necessary to improve the relevant production standards, laws and regulations, and improve the capacity of biodegradable microplastics and the degradation capacity of plastic wastes.
