Effects of Dusting Drop and Acid Rain Pollution to Distribution Characteristics of Heavy Metals in Celery

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.
