| 摘 要： | 通过环境监测数据和灰霾观测站气象资料,评价珠江三角洲地区2005-2009年灰霾污染程度,分析大气污染颗粒物与灰霾天气的关系,反映该地区居民灰霾污染暴露水平。结果显示,珠三角地区2005-2009年灰霾天气总体趋势为广州市稳中有降,东莞、深圳和肇庆三城市先升后降,每年灰霾天气具有明显季节性变化。四城市灰霾天气污染水平均以等级指数2轻微灰霾天气为主,PM10、SO2和NO2,3种大气污染物与灰霾等级指数回归分析具有显著性的正相关效应。珠三角地区属于灰霾高发区,灰霾污染较为严重。

| Abstract: | Environmental element characteristics,climate information of haze were collected to evaluate haze pollution status over Pearl River Delta(PRD)during 2005 to 2009,and influences of atmosphere pollutants on haze were analyzed to reflect the haze exposure level of the public.Results showed that general trend of haze days was stable with a little decline in Guangzhou during this period,but it was ascend in first and descend at last in other three cities as Dongguan,Shenzhen and Zhaoqing.There was seasonal variability of annually haze days.Main haze pollution index was Level 2(light haze)over PRD.Results of regression analysis indicated that there were markedly positive correlation effects between air pollutants such as PM10,SO2,NO2 and haze.It was high incidence of haze over PRD and haze pollution was serious. |
