摘要： 在温室条件下模拟酸雨、降尘对芹菜进行不同的受试处理，并对茎、叶中重金属元素的含量进行了测试。结果表明，对于芹菜茎，酸雨使Zn，Cu，Ni，Pb含量增加，Fe的含量减少，Mn，Cd含量几乎不受影响；降尘使Zn，Mn，Ni，Fe，Cd含量增加，使Cu，Pb含量减少；酸雨和降尘联合作用使7种元素含量都增加。对于芹菜叶，酸雨使Cu，Zn，Mn含量增加，Fe的含量减少，Pb，Ni，Cd的含量对不同pH有增有减；降尘使Zn，Mn，Cd，Fe的含量增加，使Cu，Pb，Ni含量减少；联合作用使叶的Zn，Cu，Mn，Cd，Fe含量增加，Pb，Ni含量减少。7种元素在茎、叶中的聚类分析表明，茎中Cu-Ni协同作用显著，Fe-Cu拮抗作用显著；叶中Cu-Pb协同作用显著，Fe-Mn拮抗作用显著。

Abstract: In this article,acid rain and dusting were simulated in greenhouse condition and celery was treated in various ways.The contents of heavy metals in stems and leaves were determined.The results showed that as to the celery stems,acid rain raised the contents of Cu,Zn,Ni,Pb,and reduced the content of Fe,but the contents of Mn,Cd were hardly changed.Dusting raised the contents of Zn,Mn,Ni,Fe,Cd and reduced the contents of Pb,Cu.Acid rain combined with dust raise the contents of seven elements.As to the celery leaves,acid rain raised the contents of Zn,Cu,Mn and reduced the contents of Fe and the contents of Pb,Ni,Cd changed with the different pH.Dusting raised the contents of Zn,Mn,Cd,Fe and reduced the contents of Cu,Pb,Ni.The combined effects raised the contents of Zn,Cu,Mn,Cd,Fe and reduced the contents of Pb,Ni.The category analysis to the contents of heavy metals in stems and leaves showed that to the stems syn-action between Cu and Ni,and the anti-action between Fe and Cu were obvious.To the leaves,the syn-action between Cu and Pb,and the anti-action between Fe and Mn were obvious.
