多氯联苯在紫花苜蓿体内的积累、分布及形态

The accumulation,distribution and chemical speciation of PCBs by different parts of alfalfa from soil were investigated.The results indicated that the total PCBs concentrations in the different parts of alfalfa can be arranged as root nodules>roots>shoots,however,the amounts of total PCBs accumulated in the different parts of alfalfa were in the order of roots>shoots>root nodules,and the difference reached significant level,alfalfa roots were the main enrichment parts of PCBs in plant.A chemical sequential ...
