[Correlation of polycyclic aromatic hydrocarbons (PAHs) in PM10- phoenix tree leaves-soil system of a coking & chemical factory in Shanghai].
In order to study the distributions characteristics, sources and relationship of PAHs in PM10- phoenix tree leaves-soil system of a coking & chemical factory in Shanghai, the samples of PM10, phoenix tree leaves and soil around the factory were collected for a year. The concentration of PAHs were analyzed according to the USEPA method 8 000 series. The results showed that the average concentration of PAHs in PM10, phoenix tree leaves and soil were 101.11 ng/m3, 79.45 ng/g and 121.53 microg/g, respectively. Particulate phase (PM10) contained mainly carcinogenic and mutagenic PAHs, among which BaA, BghiP, Flu and BaP were found at significant concentrations. In phoenix tree leaves, Nap,Chy, BaP and BghiP presented a higher level of concentration. In soil, 3 and 4-ring PAHs presented a higher level. PAHs concentrations of phoenix tree leaves were very lower in May. Only Ace (0.16 ng/g) and Pyr (0.63 ng/g) were detected. In July and August the concentrations (39.19 ng/g and 150.94 ng/g, respectively) were uplifted significantly. It could be concluded PAHs was from petroleum and coal-fired compound source. There were very strong positive relationships of 16 PAHs level among phoenix tree leaves, soil and PM10 (p < 0.01).
