| 摘 要： | 夏季受东南季风、湖流等因素影响,太湖蓝藻向西北部水域集聚,该区域平均藻密度可高达1×109个/L以上,其中蓝藻集中堆积的近湖岸区域藻类密度更高,蓝藻在不同生命阶段释放的藻源性VOCs的成分谱和产生量有较大差异,其中烯烃和有机胺反应活性较强。蓝藻水华高发期太湖西岸非甲烷总烃的浓度约为常州市区的3.3倍,日变化趋势符合蓝藻代谢规律。太湖西部蓝藻水华、湖西区的非甲烷总烃浓度和臭氧污染程度时空变化规律表明:太湖西部(宜兴)是整个流域臭氧污染最严重的区域,其臭氧污染的形成与太湖蓝藻水华暴发有关联性。

| Abstract: | Influenced by southeast monsoon and lake current, algae gather in the northwest Taihu Lake in summer andthe peak density of algae reachesabove 1×109cells/L.The number is even higher in the lakeshore, where the algae accumulating. Our study result showed that there is large variance between the main characteristics and the production of VOCs dissolved by algae in their different life stages, among which, alkenes and organic amine has a comparatively stronger reactivity. The concentration of local non-methane hydrocarbon (NMHC) in summer is 3.3 times higher than it in urban area of Changzhou, also its daily variation trend is according with the metabolism rule of algae.The temporal and spatial changes of algal bloom acreage of the western area of Taihu Lake, the concentration of non-methane hydrocarbon (NMHC) in western Taihu Lake area and the pollution level of ozone reveals that the western area (Yixing City) of Taihu Lake is the worst ozone pollution area in whole of the Taihu basin, and it has a great relationship with the algal bloom in Taihu Lake. |
