合成革工业区绿化植物重金属污染现状分析

The situation snalysis of the heavy metal pollution of plant in synthetic leather industrial

以远郊绿化区植物为对照,分析合成革工业区绿化植物叶片中重金属元素(Mn、Cd和Cr)的含量。结果表明,同一种植物对不同类型污染物吸收净化能力不同,不同种植物对同一类型污染物的吸收净化能力也不同。合成革工业区植物叶片的重金属含量总体上高于远郊绿化植物区,Cr污染尤为突出。此外,工业区重金属污染较为严重,海桐和雪松对Mn富集能力强;构骨和香樟对Cd的富集能力强;栀子花和女贞对Cr的富集能力强。

In comparison with the exurb green plants,this paper analyzed the heavy metal element（Mn,Cd and Cr） content of green plant leaves in synthetic leather industrial area.The results showed that the purify ability to absorb different types of pollutants for the same kind of plants was not the same,and to absorb the same types of pollutants for different kind of plants was also not the same.The heavy metal content of plant leaves in Synthetic leather industrial zone was higher than that in the exurb green plant area,Cr pollution particularly outstanding.It suggested that the heavy metal pollution in synthetic leather industrial area was relatively serious and indicated that the enrichment ability to Mn of Pittosporum tobira and Cedrus deodara was strong,to Cd of Ilex cornuta and Cinnamomum camphora was strong,and to Cr of Gardenia jasminoides and Ligustrum was strong.
