| The contents of 16 polycyclic aromatic hydrocarbons（PAHs）,18 polychlorinated biphenyls（PCBs）and 21 organochlorine pesticides（OCPs）in different parts of 135 Camellia oleifera samples and corresponding soil from 45 sample points in China were analyzed by GC-MS/MS to clarify the pollution distribution characteristics of persistent organic pollutants(POPs) in Camellia oleifera,also the correlations among the main POPs in Camellia oleifera seed kernel and Camellia oleifera forest soil were analyzed respectively. The results showed that the PAHs pollution of different parts of Camellia oleifera fruit and Camellia oleifera forest soil were mainly PAHs with low ring such as Nap, Acy, Ace,Fl and etc.; PCBs pollution was very light,the contents were all less than 1 μg/kg; OCPs pollution were mainly Dieldrin, Toxaphene, α-BHC, Endosulfan, Endrin and Aldrin. There was a strong positive correlation between Fl and Phe in Camellia oleifera seed kernel (R2=0.90).Flu and Phe, Chr and BaA, BbF, Bkf, BaP and BaA, PCB138 and InP, PCB180 and BghiP, p,p′-DDE and o,p′-DDT, p,p′-DDD had strong correlation (R2=0.81-0.98) in the Camellia oleifera forest soil. |
