测定了珠江三角洲130个表层沉积物中总有机碳(TOC)和10类卤系阻燃剂(HFRs)的含量,并探讨了TOC与HFRs之间的关系。结果表明:珠三角表层沉积物TOC范围为0.16%~5.76%,平均值为1.25%,呈现明显的空间变化。在工业化程度较高的东莞和广州,沉积物中HFRs与TOC有显著的相关性,而西江和珠江口沉积物中HFRs与TOC的相关性较差,可能与珠江三角洲水动力过程、电子垃圾拆解活动和HFRs不同的来源有关。 |

Total organic carbon(TOC)and halogenated flame retardants(HFRs)in 130surface sediments from the Pearl River Delta(PRD)were determined,and their correlations were discussed.Results suggest that concentrations of TOC in sediments significantly vary,with the range and mean value of 0.16%-5.76%and 2.10%,respectively.Correlations between HFRs and TOC are significant positive in sediments from highly industrialized areas,such as Dongguan and Guangzhou,but not in sediments from low industrialized areas,such as the Xijiang River and the estuary.Those results could ascribe to the complicated hydrodynamic processes in PRD,waste dismantling activities and the different sources of HFRs. |
