摘要
根据“淮安市绿色食品基地调查以及相关研究”课题资料 ,分析了水稻中重金属含量与其土壤质量的关系。结果表明 ,重金属含量在水稻中的分布是 :根 >茎叶 >籽粒 ;水稻籽粒对重金属的吸收特点因其元素不同而差异较大 ,重金属元素被水稻糙米吸收的程度为 :砷 <镉 <汞 <铅 <锰 <铬 <铜 <锌 ;在糙米中检出的重金属铜和铬的含量与土壤中铜和铬的含量呈显著性相关关系 ,铅、锌、锰的含量与土壤中铅、锌。
Relationship of heavy metals contained in paddy rice and soil quality was researched base on related materials. The content of heavy metals in paddy rice was, roor>stem>seed. Adsorption of heavy metals in seed was different. For brown rice, it is As<Cd<Hg<Pb<Mn<Cr<Cu<Zn. The content of Cu and Cr traced from brown rice had significant correlation with the content of Cu and Cr in soil, and there had no significant correlation for Pb, Zn, Mn.
