| 摘 要： | 按季节对杭州市大气细颗粒物PM2.5中16种多环芳烃(PAHs)的含量在2006年进行了为期一年(样本数n=47)的测定分析.研究表明,杭州市大气PM2.5中PAHs总浓度为40.66ng/m3,以中环或高环为主,分别占总PAHs的32.23%和47.6%;云栖点位(位于风景名胜区内)PM2.5中PAHs浓度高于朝晖点位(位于商业居民混合区);季节变化呈现春季高,秋季低的特点;PM2.5中苯并a]芘等效毒性(BEQ)为4.50;PM2.5中PAHs的来源不是单一的.

| Abstract: | Eutrophication of Taihu Lake are more severe than before.This paper studied the regional and time period character,and the water quality change of blue-green algal blooms in Taihu Lake,based on the analysis of monitoring data. It pointed out that the blue-green algal blooms in Taihu Lake present multi-peaks state.In 2007,the character with two peaks and three stages of algal biomass in Shazhu indicated that the outbreak of blue-green algal blooms in Taihu will be more frequent. |
