PAH characteristics and genotoxicity in the ambient air of a petrochemical industry complex
- National Cheng Kung Univ., Tainan (China)
Polycyclic aromatic hydrocarbons (PAHs) samples, at four sampling sites, in the ambient air of petrochemical plants were collected by several PS-1 samplers from October 1993 to July 1994 in a petrochemical complex area located in southern Taiwan. In addition, the genotoxicity of the PAH samples were investigated by the Ames Salmonella/microsomal assay system. The winter/summer ratios of total-PAH composition were 0.60, 1.39, 2.97, and 1.28 for sites A, B, C, and D, respectively. This result implied that wind direction is the most significant parameter affecting the total-PAH composition in these four sampling sites. Sampling sites B, C, and D were located on the downwind side of the petrochemical plant and gave higher total-PAH composition than those of sampling site A. Particle phase PAHs had higher mutagenicity than those in the gas phase.
