摘 要: 利用LevelⅢ环境多介质逸度模型模拟稳态、定量输入条件下上海市环境介质中16种多环芳烃(polycyclic aromatic hydrocarbons, PAHs)富集、迁移归趋过程及规律特征。结果表明:理化性质是决定PAHs多介质环境迁移归趋的主要因子,随着PAHs分子量的增加,其在土壤和沉积物中的浓度和富集量递增,而在大气中PAHs的浓度和含量越来越低,同时各相间迁移通量、平流降解损失、停留时间等也呈规律性的递增和递减变化。
关 键 词: 环境学;多环芳烃;逸度模型;多介质迁移;归趋模拟

Abstract: The LevelⅢ multimedia environmental fugacity model was used to simulate the enrichment, migration and fate process of sixteen polycyclic aromatic hydrocarbons (PAHs) in Shanghai environmental media under the condition of steady-state and fixed amount input. The results showed that migration and fate process were majorly dictated by the inherent physicochemical properties of PAHs, with the PAHs molecular weight increasing, the concentration and accumulation of PAHs in soils and sediments increased, while the PAHs concentration and content in atmosphere was getting lower and lower. At the same time, the migration flux, advection degradation loss, retention time also showed the regularity of the increment and decrement change.
Key words: environmentology; polycyclic aromatic hydrocarbons; fugacity model; multimedia migration; fate simulation
