| 摘 要： | 2006年6月~2008年5月,在杭州市采集了大气降尘和PM10样品以及3类PM10源样品,对样品中12种无机元素进行了分析.结果表明,杭州市大气降尘量与PM10浓度相对于国内其他城市均属于较低水平,二者的季节变化存在明显差异;降尘量和PM10浓度的空间分布特征存在相似性,均与人类活动的强度密切相关.空间分布显示除PM10在朝晖和玉泉两采样点的成分谱相似,各采样点降尘和PM10成分谱间的相似性均不高.PM10与各源类成分谱的相似性高于降尘与各源类成分谱的相似性,二者来源的差异可能是造成降尘和PM10化学组分特征不同的原因,其中PM10与城市扬尘的化学成分相似性最高.

| Abstract: | Samples of dustfall and PM10 as well as source samples of PM10 were collected from June 2006 to May 2008 at four monitoring stations of Hangzhou City.Twelve metals were quantified: chromium,manganese,nickel,lead,zinc,cobalt,aluminum,iron,potassium,sodium,calcium and magnesium.The deposited dust amount and concentration of PM10 was lower than most of the other cities in China.The dustfall and PM10 had different seasonal changing-mode.The similarity of spatial distribution implicated that both the amount of d... |
