ABSTRACT
Objective To study the distribution of polycyclic aromatic hydrocarbons (PAHs)on different diameter atmospheric particulates in winter and summer respectively. Methods Atmospheric particulates in the atmosphere of Hengyang urban districts were collected using DFJ-1 model five-stage classification air sampler in the winter and summer. The contents of PAHs on different diameter atmosphere particulates were detected by GC-MS. Results The PAHs were found on different diameter atmosphere particles. The PAHs contents in the atmosphere in the winter and summer were 161.42?140.72 ng/m3. 52.3% and 63.3% PAHs distributed in the fine partioulates with dicameter ≤2.0 ?m in the summer and winter. Conclusion The PAHs contents in the atmosphere during winter were higher than that during summer,and the PAHs were mainly distributed in the fine particulates with diameter≤2.0 ?m. The distribution characteristics of different kinds of PAHs on different diameter atmospheric particulates were not unanimous. The distribution of PAHs in winter changed significantly.
