A 3D hydrodynamic and contaminant fate model was implemented for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in Thau lagoon. The hydrodynamic model was tested against temperature and salinity measurements, while the contaminant fate model was assessed against available data collected at different stations inside the lagoon. The model results allow an assessment of the spatial and temporal variability of the distribution of contaminants in the lagoon, the seasonality of loads and the role of atmospheric deposition for the input of PCDD/Fs. The outcome suggests that air is an important source of PCDD/Fs for this ecosystem, therefore the monitoring of air pollution is very appropriate for assessing the inputs of these contaminants. These results call for the development of integrated environmental protection policies.
一个用于多氯二苯并对二恶英和多氯二苯并呋喃(PCDD/Fs)的三维水动力和污染物归宿模型在索恩泻湖得到了实现。水动力模型经过了温度和盐度测量的检验,而污染物归宿模型则是根据在泻湖内不同站点收集的现有数据进行了评估。模型结果允许对污染物在泻湖内的分布的时空可变性、负荷的季节性以及大气沉积对 PCDD/Fs 输入的作用进行评估。结果表明,空气是该生态系统中 PCDD/Fs 的一个重要来源,因此对空气污染的监测非常适合评估这些污染物的输入。这些结果呼吁制定综合的环境保护政策。
