大气颗粒物中水溶性无机离子的研究进展

Research progress of water-soluble inorganic ions in atmospheric particles

大气颗粒物已成为我国大部分城市的重要污染物,并引起了广泛关注。水溶性无机离子作为其重要组成成分更是研究领域的热点。介绍大气颗粒物中水溶性无机离子的性质、危害、来源方面的相关知识,对国内外不同粒径大气颗粒物中水溶性无机离子的相关研究做出对比、分析和总结。由于高原地区地理位置的独特性,把高原地区大气颗粒物中水溶性无机离子污染现状单独分析并与平原地区做出对比,分析一致性和差异性。从源解析技术的验证评估、优化城市规模、完善大气污染管理法律法规体系3个方面,分析研究工作存在的局限性并做出展望。

Atmospheric particulate matter has become an important pollutant in most cities of China and has attracted wide attention. Water-soluble inorganic ions as an important component of inorganic ions is a hot research field. This paper introduces the properties, hazards and sources of water-soluble inorganic ions in atmospheric particles,and compares, analyzes and summarizes the relevant researches on water-soluble inorganic ions in atmospheric particles with different particle sizes at home and abroad. Due to the uniqueness of geographical location in plateau area,the present situation of water-soluble inorganic ion pollution in atmospheric particulate matter in plateau area is analyzed separately and compared with plain area to analyze consistency and difference. The limitations of the research work are analyzed and prospected from three aspects: verification and evaluation of source analysis technology, optimization of city scale and improvement of laws and regulations system of air pollution management.
