  • 摘要: 以典型二噁英(PCDDs)和多氯联苯(PCBs)为研究对象,利用TaPL3模型模拟计算了稳态假设下北京地区4种PCDDs和7种PCBs通过大气和水体的长距离迁移潜力(LRTP)和总持久性(Pov),比较了不同氯取代数的特征迁移距离(CTD)和Pov的大小,分析讨论了二者之间的关系,并以PCB180为例对关键参数进行了灵敏度分析.结果表明,4种PCDDs和7种PCBs在北京地区通过大气的CTDair范围分别为714—874 km和1771—8517 km,Povair范围分别为1422—5169 d和1210—35687 d;通过水体的CTDwater范围分别为1232—1385km和643—4222 km,Povwater范围分别为4900—5618 d和1831—35922 d.对于PCDDs,CTD和Pov基本上随着氯取代数目的增加而增大;对于PCBs,Pov的变化规律与PCDDs类似,而通过大气和通过水体的CTD的变化规律不同.CTD和Pov没有表现出直接的关系.与国内外同类研究相比,北京地区的结果和国外接近,但高于兰州地区通过大气的CTDair,低于通过水体的CTDwater.
    Abstract: Long-range transport potential (LRTP) and overall persistence (Pov) of 4 PCDDs and 7 PCBs through air and water in Beijing were estimated using TaPL3 model. The characteristic travel distance (CTD) and Pov of PCDDs and PCBs with different numbers of substituted chloride were compared and the relationship between CTD and Pov was discussed. In addition, sensitivity analysis was performed on the selected key parameters using PCB180 as an example. The results indicated that the CTDair ranged from 714 km to 874 km for PCDDs and 1771 km to 8517 km for PCBs, respectively. The Povair ranged from 1422 d to 5169 d for PCDDs and 1210 d to 35687 d for PCBs, respectively. Similarly, the CTDwater are 1232—1385 km and 643—4222 km for PCDDs and PCBs, respectively; the Povwater are 4900—5618 d and 1831—35922 d for PCDDs and PCBs, respectively. The CTD and Pov increase with the number of substituted chloride of PCDDs. Pov of PCBs exhibits similar trend as PCDDs while the variation of CTDairand CTDwater differ. No direct relationship between CTD and Pov was found. Compared with other similar studies, the CTD and Pov in Beijing are comparable to those overseas, whereas the CTDair is higher and CTDwater is lower than those in Lanzhou.
