摘　　要：近年来,环境中微塑料的污染问题备受关注。对太原市新沟垃圾填埋场的矿化垃圾及其周边(距离2 km以内)普通土壤中微塑料的成分特征进行了分析。结果表明:矿化垃圾和普通土壤中微塑料的平均丰度分别为2113、172个/kg。矿化垃圾和普通土壤中微塑料的形状、颜色、粒径分布和成分大致相似,区别在于:矿化垃圾中单独检出黄色和蓝色微塑料,单独检出聚乙烯醇成分,大粒径微塑料占比较高;普通土壤中单独检出白色和红色微塑料,单独检出聚酯纤维成分,小粒径微塑料占比较高。Recently,the pollution problem of microplastics in the environment has attracted much attention.This paper investigated the characteristics of microplastics in aged refuse of Xingou landfill in Taiyuan and ordinary soil within 2 km to the landfill.The results showed that the average abundance of microplastics was 2113 and 172 particles/kg in aged refuse and ordinary soil,respectively.The main shape,color,particle size distribution and composition of the microplastics in aged refuse and ordinary soil were similar.However,there were some differences between them.The yellow and blue microplastics,higher proportion of large particle size microplastics,and PVA were detected in aged refuse individually.The white and red microplastics,higher proportion of small particle size microplastics,and polyester were detected in ordinary soil individually.
