Levels and Distributions of Six Toxic PAHs in the Urban Air of Dalian, China During Heating Periods

Abstract:

^{Superscript text}^{Superscript text}The concentration of six potential carcinogenic compounds (3-Methylcholanthrene, Dibenz(a,h)acridine, Dibenz(a,i)acridine, Dibenzo(a,e)pyrene, Dibenzo(a,h)pyrene, Dibenzo(a,i)pyrene ) in the urban air of Dalian, China were monitored from November 2009 to March 2010 with active high-volume sampler. They were detected in gaseous phase and particulate phase, respectively. The total concentration of them was 563.2 pg m^-3, and they were mainly found in particulate phase with the concentration of 540.5 pg m^-3 while the concentration in the gas phase only was 22.7 pg m-3. The concentration of them changed apparently in different month.
