| 中文摘要 | Short chain chlorinated paraffins (SCCPs) were determined in a sedimentary core T06 from the Zhejiang-Fujian Mud Area of the East China Sea (ECS). The contents of SCCPs varied from 9.38 to 41.55 ng/g (dry weight, dw) with an average of 22.88 ng/g (dw), while the deposition flux ranged from 80.10 to 347.36 mu g/m(2).y. Both the contents and the deposition flux presented an increasing trend toward the core top, indicating enhanced inputs of SCCPs into the ECS in recent years. The lower carbon length (C-10) and lower chlorinated (Cl-5, Cl-6 and Cl-7) homologues were the most predominant congeners, demonstrating that they are from long-range atmospheric deposition or ocean current transportation. A significant positive relationship between the contents of TOC and SCCPs was found (R-2 = 0.597, p< 0.05). The contents of terrestrial organic matter indicator of C-27+C-29+C(31)n-alkanes also presented an increasing trend, similar to that of SCCPs. Correlation analysis also showed a significant but weaker linear relationship (R-2 = 0.363, p< 0.05) between SCCP contents and C-27+C-29+C(31)n-alkane contents. These correlations suggest that sedimentary SCCPs in core T06 are mainly from river inputs through Yangtze River, similar to those terrestrial organic matters preserved in the inner shelf of the ECS. |
