Phthalic esters in atmospheric particulate of different diameter in Huhehaote urbanarea TONG Qing, ENG Shenying, RUAN Yuying, ZHAO Tianjiao, YANG ang, WANG Zhongen ( Inner Mongolia Monitoring for Environmental Protection, Huhehaote 010010) Abstract A report was given on theanalysisfor phthalicesters in different diameter air borne particles of Huhehaote urban atmosphere with five stage classification air samples inw inter and summer. Results show 3 that the concentration of PAE w as 6. 83 74. 4 ng/ m in different diameter airborne particles. About 725% 91. 2% of PAE was concentrated in the aerodynamic diameter 7. 0 m and about 100% 455% of PAE was concentrated in that w ith diameter 1. 1m.
