以东海陆架水体中溶解态多环芳烃(PAHs)含量为基础,引入颗粒相-水相间的物质吸附系数(K_(oc))计算悬浮颗粒物中PAHs有机碳归一化含量,结合陆架沉积物有机碳的年埋藏通量,估算东海陆架沉积物中PAHs沉积通量。结果显示:水体中溶解态的15种PAHs总含量为(701 ± 392) ng/L,变化范围为412~1 032 ng/L,PAHs组成以3环为主。计算得到的悬浮颗粒物中15种PAHs有机碳归一化含量为.20~28 μg/g,对应的PAHs沉积通量为150~210 t/a。估算结果与实测沉积物中PAHs含量和沉积通量结果基本吻合,表明实验室模拟实验获取的化合物K_∝值适用于东海颗粒相一水相间的分配模型,证实悬浮颗粒物有机碳含量在控制PAHs两相分布过程中起着重要作用。同时,该方法为海洋沉积物中PAHs沉积通量的估算提供一种新途径。 |

Eleven surface seawater samples collected over the East China Sea (ECS) were analyzed for polycyclic aromatic hydrocarbons (PAHs) in dissolved phase. An estimation of particulate-phase PAH fluxes was performed by using the organic carbon adsorption coefficient (K_(oc)) from an experimental data and total organic carbon burial flux in the ECS. The measured concentrations of total 15 dissolved-phase PAHs in the water samples ranged from 412 to 1 032 ng/L, with the average value of (701 ± 392) ng/L, which were predominated by the three ring PAHs. It is estimated that the concentrations of 15 PAHs in particulate phase were from 20 to 28 μg/g and the total deposition flux of the ECS was from 150 to 210 t/a. The estimated results are consistent with measured concentrations and fluxes of PAHs in the sediments, suggesting feasibility of Koc values-based method for rapid estimation of deposition fluxes of PAHs in this area. The design and implementation of the method is a new quantitative way attempt to estimate PAH fluxes in marine sediment. |
