| 摘 要： | 建立了估算苯并 (a)芘在天津污灌区气、水、土壤及沉积物相间的迁移通量和浓度分布的逸度模型框架 ,利用通量资料作为模型输入 ,利用实测浓度数据验证了模型的可靠性 .结果表明 ,模型对大气、地表水、土壤和沉积物中浓度的估算大体吻合 ,沉积物和土壤是苯并 (a)芘的主要环境归宿 ,而大气中的平衡浓度相对较低 ,水体及土壤中的苯并 (a)芘可能通过作物和鱼体富集而进入生态系统 .

| Abstract: | A level of fugacity model was applied for elucidating the fate and among-phase transfer flux of benzo(a)pyrene in wastewater irrigated area in Tianjin. The results revealed that estimated concentrations of benzo(a)pyrene in air, soil, and sediment compartments were in good agreement with observed values. Soil and sediment are the primary sinks of benzo(a)pyrene in the area. There is no suitable data available for validation of calculated concentration in water. More data related to sediment are necessary for a better modeling. |
