本文采用化学热氧化法测定了25个东海内陆架表层沉积物中黑碳的含量,探讨了沉积物中黑碳与总有机碳、粒度以及持久性有机污染物之间的关系.结果表明,东海内陆架表层沉积物中黑碳的含量范围为0.21~0.88 mg.g-1.沉积物中黑碳和总有机碳之间没有显著的相关性,表明两者具有不同的来源.区域内沉积物在粒度上有明显的空间分异,黑碳的空间差异则较小,表明黑碳的沉积过程受颗粒物分选过程的影响较小.沉积物中多环芳烃和滴滴涕的含量与黑碳无显著的相关性,可能与东海内陆架环境中强烈的水动力过程和持久性有机污染物来源的复杂性有关. |

Concentrations of black carbon(BC) were determined in the surface sediments from the inner continental shelf of the East China Sea(ECS).For comparison,the total organic carbon(TOC) contents,grain size distribution,concentrations of PAHs and DDTs in the sediments were also measured.Total concentration of BC ranged from 0.21 mg·g-1 to 0.88 mg·g-1,with the highest level in the depositional center of Yangtze-derived fine particles.Correlation was found to be insignificant between BC and TOC in the surface sediments,suggesting that they possibly came from different sources.The sediment particles showed significant spatial variations,whereas no significant spatial difference was found in BC content,indicating that the deposition process of BC was not controlled by particle size separation.In addition,a poor correlation between BC and PAHs or DDTs was reported in the estuarine-coastal sediments,probably due to the complicated hydrodynamic process and the heterogeneous sources of PAHs and DDTs. |
