Regional Background Value Investigation and Health Risk Evaluation of PAHs in Shandong Province Atmospheric Particles
Polycycllc aromatic hydrocarbons (PAHs) were determined in total suspended particles(TSP) sampled from 7 different typical cities in Shandong province, China. The sum of sixteen EPA priority PAHs concentrations ranged from 56.22 to 612.93 ng per cubic meter in heating season and from 7.18 to 127.79 ng per cubic meter in nonheating season in Shandong region. The levels of PAHs concentration background in Shandong province Changdao was also higher than others. All the PAH species were detected in nonheating season but DahA and BghiP were not detected in heating season in Changdao background. In spite of PAHs concentrations background in Changdao, the ratio of BaP to the sum of sixteen PAHs equivalent concentration in Changdao in heating season was the highest and the contribution proportion was up to 71.94 percent. The regression equations with very good correlationships were set up including concentrations of BaP, TSP and sum of sixteen PAHs in Shandong province in different seasons, the correlation coefficient square respectively 0.996 and 0.979, which were used to evaluate the PAHs health risk in atmospheric particles.
