青岛市环境空气臭氧污染特征分析

摘要

青岛市是国家环保部确定的臭氧试点监测城市之一。文章结合青岛市市南区东部和四方区空气子站2008-2011年的试点监测数据，从区域差异、时间变化等方面分析了青岛市的臭氧污染特征，结果表明：①二区域臭氧浓度的日分布均呈现“单峰型”，12：00～15：00是一天中臭氧污染最严重的时段；②每月监测累积值市南区东部呈现“双峰型”，四方区呈现“单峰型”；③二区域臭氧污染最突出的月份均为5月；④二区域臭氧平均浓度从高到低季节排序略有差异；⑤2009年二区域臭氧污染最严重，该年四季中春季臭氧污染最为突出。%Qingdao is one of the designated trial cities for Ozone monitoring by National Environmental Protection Ministry.In this article,combine with the reference of the trail data of the substation in east part of ShiNan and SiFang district from 2008 to 2011,we analyze the pollution feature of ambient Ozone in the aspect of area differences and time variations.The results show that:① The daily distribution of Ozone presents one -peak pattern in these two districts,during which Ozone pollution is the most serious from 12 to 15 o’clock;② The monthly accumulated value appears two -peak pattern in East ShiNan,and one -peak pattern in SiFang;③The outstanding pollution of Ozone is in May in these two districts;④ There is slight difference in the sort of Ozone average from highness to lowness between these two districts;⑤ 2009 is the most Ozone -polluted year in the two districts,and the ozone pollution in spring is the most serious in the four seasons of the year.
