| 摘 要： | 应用Ⅲ级多介质逸度环境模型研究了研究区3种有机氯农药p,p-’DDT、p,p-’DDE、p,p-’DDD的多介质行为。模型的计算结果表明:在研究区大气、水和沉积物中p,p-’DDT的浓度分别为0.019 8g/m3、0.016 8ng/L0、.313ng/g;p,p-’DDE的浓度分别为0.019 9g/m30、.001 65ng/L、0.124ng/g;p,p-’DDD的浓度分别为0.001 98g/m3、0.004 68ng/L、0.083 2ng/g。沉积物中的有机氯农药的含量占环境中有机氯农药总滞留量的99%以上,是有机氯农药的最主要的汇。然后计算了3种有机氯农药在环境中的相间迁移通量,其中水-沉积物迁移和沉积物-水迁移是最重要的迁移过程。

| Abstract: | This paper examines the multimedia environmental behavior of three kinds of organochlorine pesticides, p,p'-DDT、p,p'-DDE、p,p'-DDD in a bay of Hainan, China. A fugacity level Ⅲ multimedia environmental model is used. The model results indicate that the concetrations of p,p'-DDT in air, water and sediment are 0.019 8g/m~3,0.016 8ng/L,0.313ng/g, respectively; p,p'-DDE is 0.019 9g/m~3,0.0016 5ng/L and 0.124ng/g, respectively; p,p'-DDD is 0.0019 8g/m~3, 0.004 68ng/L, 0.083 2ng/g, respectively. Sediments are the most important sinks, which accumulate to more than 99% of the total organochlorien pesticides. The transfer mass of p, p' -DDT, p,p' -DDE, p,p' -DDD are also calculated. The results show that transfer processes on interfaces of the water-sediment and sediment-water are the primary routes for organochlorine pesticides. |
