摘要
为了弄清大气中微粒子的化学组成的特征,我们自2001年12月在成都市采集了干性降落物和道路粉尘,并对其水溶性阴离子成分进行了比较。通过分析认为干性降落物对道路粉尘的化学组分有影响。同时道路混凝土的污染物亦可进入道路粉尘。
In order to reveal the chemical characteristics of atmospheric particulate matter, dry deposition and road dust were collected from December 2001 in Chengdu. Their water soluble anion components were measured and compared.Through analysis, it is revealed that dry deposition has effects on the chemical characteristics of road dust, meanwhile the pollutants in road concrete also possibly mix into road dust.
