Study on Heavy Metal Enrichment of Cherries and Soils in Cherry Growing Region
摘要
Abstract
To study the enrichment of heavy metals in cherry growing area and its relationship with soil heavy metal content in arid cherry growing area in Northwest China,the enrichment condition of heavy metals in soil and cherry was evaluated using Nemerow index and enrichment index.The results showed that with the "soil environment quality standard" as the evaluation criteria it was found that the soil of cherry growing area was not seriously polluted by heavy metals.From the view of the spatial distribution pattern of heavy metals in the soil,the heavy metal pollution in the northeast soil was more serious than that in the southwest;the contents of Cd,Cu,Pb,Zn,Cr in various parts (leaf,peel and pulp) of cherry were different,the contents of Pb,Cr and Cd in the leaf and peel were higher than the standard;the content of Pb and Cd exceeded the standard in the pulp.In addition,the accumulation of heavy metals in different parts of cherry had a big difference,and the overall trend was leaf ＞ peel ＞ pulp.While the abilities that different heavy metals were absorbed by the same organ were different,and the enrichment abilities of heavy metals were also different.The enrichment abilities of heavy metal elements in the leaf was in the order of Cd ＞ Cu ＞ Pb ＞Zn ＞ Cr;the enrichment ability of the heavy metal elements in the peel area were Cd ＞ Cu ＞ Zn ＞ Pb ＞ Cr;the enrichment ability of the heavy metal elements in the pulp was in order of Cd ＞ Cu ＞ Pb =Zn ＞ Cr.In conclusion,the enrichment index of Cd in leaf,peel and pulp of cherries was the largest,which indicated a strong potential ecological risk.关键词
