南京市大气气溶胶中酞酸酯的分布特征

利用分级采样器采样 ,高效液相色谱检测 ,研究了南京市春夏秋冬四季六大功能区 (工业区 ,交通区 ,文化区 ,商业区 ,园林风景区和居民生活区 )大气气溶胶中的酞酸酯 .结果表明 :南京市大气气溶胶中检出的酞酸酯有 :邻苯二甲酸二甲酯 (DMP)、邻苯二甲酸二丁酯 (DBP)和邻苯二甲酸二辛酯 (DEHP) ,其含量随功能区和季节而变化 ,平均浓度具有工业区 >居民区 >交通区 >商业区 >文化区 >园林风景区和秋、冬季浓度高于春、夏季的分布特征

THE SEPARATION AND DETERMINATION OF PHTHALIC ESTERS IN NANJING ATMOSPHERIC AEROSOLS

Compositions of the phthalic esters(PAEs)in atmospheric aerosols,collected using a classified sampler in six different areas in Nanjing,China,are determined with a high performance li quid chromatography. These areas are classified,according to their zoning information,as industrial,traffic,cultural,commercial,scenic areas and residential,respectively.It is found that there exist the phthalic esters,which may directly affect the human health.These PAEs mainly contain dimethyl phthalate (DMP),dibutyl phthalate(DBP)and diethylhexyl phthalate(DEHP).It is also found that the concentration of those PAEs depends on the zoning area and changes with the season.It is followed by,in the decreasing order,industrial,residential,traffic,commercial,cultural and scenic areas.For all the areas,the concentration of PAEs in the fall and winter is found to be higher than in the spring and summer.
