| 摘 要： | 于2009~2010年,利用风标式花粉采集器,采集了上海不同区域春、秋、冬季的飞散花粉和大气颗粒物样品,并于春季(2010年4月)利用重力花粉采集器在不同高度采集了飞散花粉样品,以及不同区域悬铃木的花粉.对风标花粉采样器采集的样品进行溶酸处理后进行花粉鉴定;对重力法采集的花粉样品染色后直接进行观察.利用高分辨的扫描电镜(SEM)对悬铃木花粉上吸附的大气颗粒物进行了微观表征.结果显示,上海春季大气中的花粉以木本植物花粉为主.不同区域悬铃木花粉上所吸附的颗粒物组分有所差异.冬季和春季大气颗粒物(总悬浮颗粒物)中的SO42-的浓度均为所检测离子(Na+、K+、Ca2+、Mg2+、NH4+、NO3-、SO42-、Cl-)中浓度最高的,NO3-、SO42-、NH4+在冬季样品中要比春季样品中的浓度高.上海大气颗粒物中的地壳元素的质量浓度从高到低为Ca >Na>Mg>K. |
| 关 键 词： | 上海市 大气颗粒物 飞散致敏花粉 复合污染 |

| Abstract: | Ambient pollens and atmospheric particulates samples were collected in different regions of Shanghai in spring,autumn and winter from 2009 to 2010 by Pierre Cour pollen samplers.Distribution of ambient pollens at different heights were investigated by using of Durham pollen samplers in spring(April,2010),additionally,we collected Platanus grains in different regions.The pollens collected by Pierre Cour pollen samplers were identified by light microscope after the samples were treated with acids,while the po... |
