松花江流域萘的多介质环境迁移与归趋模拟

Simulation of multi-media transfer and fate of naphthalene in Songhua River

为研究多环芳烃(PAHs)——萘在松花江流域多介质中的迁移及归趋,利用Level Ⅲ多介质逸度模型模拟计算了稳态假设条件下萘在松花江环境相间的迁移和含量分布.结果表明:土壤是萘的最大储库,占总滞留量的40%;在大气、水、土壤、沉积物中,萘的含量分别为3.58×10-6μg·g-1、0.142μg·L-1、5.28×10-4μg·g-1、3.62×10-3μg·g-1.模型计算含量与同期实测含量吻合较好,验证了模型的可靠性.

Transfer and fate of naphthalene （PAHs） in multi-medium of Songhua River was studied. A level III fugacity model was applied to calculate the multi-interface transfer flux and concentration distribution of naphthalene in S^nghua River under steady-state assumptions. The results indicated that soil was the largest storage of naphthalene, accounting for 40% of the total amount of residual. In air, water, soil and sediment, the concentrations of naphthalene were 3.58 ~ 10-6 μg ~ g-1, 0. 142 μg L-l , 5.28 10-4 μg ＂ g-1 and 3, 62 ~ 10-3 μg g-1 respectively. The reliability of the model was verified by the coincidence of the calculated and the measured concentration in the same period.
