【摘要】 采用大流量采样器和五段分级采样头，对呼和浩特市冬夏两季不同粒径空气颗粒物中酞酸酯（ＰＡＥ）进行采样分析，结果表明：不同粒径的酞酸酯含量范围为６８３—７４４ｎｇ／ｍ３（标），其中富集在空气动力学当量直径＜７０μｍ以内的占７２５％—９１２％，富集在≤１１μｍ以内的占１００％—４５５％．更多还原

【Abstract】 A report was given on the analysis for phthalic esters in different diameter air borne particles of Huhehaote urban atmosphere with five stage classification air samples in winter and summer.Results show that the concentration of PAE was 6.83—74.4ng/m 3 in different diameter airborne particles.About 72 5%—91.2% of PAE was concentrated in the aerodynamic diameter<7.0μm and about 10 0%—45 5% of PAE was concentrated in that with diameter <1.1μm.更多还原
