三亚地区冬春季大气污染特征观测研究
Characteristics of air pollutants in Sanya during winter and spring
摘要
Abstract
Atmospheric pollutants including NOx,O3 and PM2�5,along with meteorological factors were intensively monitored in Luhuitou village of Sanya,which is the southernmost tip of Hainan Island,in order to study the charac⁃teristics of air pollution in Sanya. Located in the outskirt of Sanya,the monitoring station is surrounded by sea in three directions and without industrial pollution sources.From December of 2011 to April of 2013,the variation prop⁃erties of NOx,O3 and PM2�5 in winter and spring were analyzed and the sources of pollutants were investigated using backward trajectory method.The results show that,the concentrations of air pollutants in Sanya were under the values listed as first level in national standard,with the daily average value of NO,NO2,NOx,O3,and PM2�5 being (2�1± 2�2),(5�2±3�4),(7�3±3�8),(59�8±28�4),and (17�5±14�3)μg·m-3,respectively.The diurnal variations of NOx and PM2�5 showed double⁃peak patterns, with the maximum concentrations appeared at 08:00 BJ ( Beijing time) and 17:00 BJ;while the diurnal variation of O3 exhibited a single peak which occurred at 13:00 BJ.Based on backward trajectory method,it was found that pollutants in Sanya came from local and regional sources,and the con⁃tinental air mass usually led to accumulation of air pollutants,whereas the marine air masses usually diluted the air pollution.关键词
