摘要: The contamination and distribution of polychlorinated dibeinizo-p-dioxins dibenzofurans (PCDD/Fs) from two agricultural fields a heavily polluted lake area in China (Ya-Er Lake) are presented. vertical pattern total PCDD/Fs soil cores reveals that the maximum concentration was layer 20-30 cm. concentrations top at sites were similar (17.48 ng/kg Site 1 18.10 2), but (120.8 ng/kg) times higher than 2 (64.39 ng/kg). mud rice (0-50 cm) Sites 0-10 PCDD/F (203.1 2: (143.3 Significant correlations found between mind organic carbon content (R = 0.9743, P< 0,05 1; R 0.9821, 0.05 variables being highly correlated 0.9049, 0.05, 0.9916, 2). All correlation coefficients significant 95% level. Concentrations with carbon, indicating sorption to dominant mechanism. Using principal component analysis, homologue profiles soil, mud, plants (rice radish) compared. patterns not be those mud. This suggests atmospheric deposition may main source grain. However, mixed exposure involving uptake mechanisms is considered pollution radishes. (C) 2002 Elsevier Science (USA).
