The disappearance and transfer behavior of polychlorinated biphenyl (PCBs) (the mains of penta PCBs) at higher concentrations (400 mg/kg) bestrewed into semi field soil systems were studied under near field conditions (semi dry climate in North China).
利用构建的土壤半野外试验系统 ,在接近野外 (半干旱气候 )条件下 ,研究高含量 ( 4 0 0mg/kg)高氯代PCBs(以五氯代为主 )在系统中的迁移与消失规律 。
