  • 摘要: 为了解石家庄市城市道路积尘水溶性离子组分特征及来源，于2015年冬季使用移动采样法收集城市道路积尘样品，经离子色谱仪分析其水溶性离子组分，用相关性分析和比值分析法解析其污染特征，用主成分分析法初步推断其主要来源.结果表明，10种水溶性离子（Na+、NH4+、K+、Mg2+、Ca2+、F-、Cl-、NO-2、NO3-、SO42-）占道路积尘PM2.5的15.31%、PM10的11.15%，Ca2+ 和SO42-的百分含量在PM2.5和PM10中均大于1%；其中Ca2+在10种离子中所占比例最高、SO42-次之，PM2.5和PM10中NO3-/SO42-分别为0.24和0.18；颗粒物总体偏碱性，且PM2.5较PM10碱性更强；推测其来源于机动车排放、大气中燃煤、生物质燃烧和建筑尘的沉降及绿化带尘土.
    Abstract: In order to understand the pollution characteristics and sources of water-soluble ions in the paved road dust of Shijiazhuang, dust samples from 4 different types of roads were collected and analyzed in Jan.2015. The contents of 10 water-soluble ions were measured by ion chromatography, pollution characteristics were analyzed by Pearson correlation analysis and ratio analysis, and the main source was inferred by principal component analysis. The results showed that the sum of 10 water-soluble ions(Na+,NH4+,K+,Mg2+,Ca2+,F-,Cl-,NO-2,NO3-,SO42-)in road dust was 15.31% PM2.5, and 11.15% PM10, Ca2+ and SO42- in PM2.5 and PM10 were more than 1%. The proportion of Ca2+ was the highest in all ions, followed by SO42-. The values of NO3-/SO42- in PM2.5 and PM10 were 0.24 and 0.18. The particles were generally alkaline, and the alkaline of PM2.5 was stronger than PM10; The sources were related to motor vehicle emission, deposition of coal combustion, biomass burning and building dust in the atmosphere, and dust entering road from green belts.
