摘要
为探讨河北省张北地区土壤和莜麦中重金属元素含量及健康风险,选择17个适宜采样点进行表层土壤和莜麦籽实样品的采集,通过单因子污染指数法、综合污染指数法和富集系数分别对土壤质量和重金属元素从土壤向莜麦迁移能力进行研究。结果表明:研究区土壤和莜麦中重金属含量远低于国家标准,品质安全健康;区内重金属元素在土壤-莜麦系统中富集能力为Zn>Cu>Ni>Cd>As>Pb>Cr=Hg, Ni、Cu和Zn的富集系数远高于Cr、As、Cd、Hg、Pb, Cd迁移能力很弱,As、Pb几乎不发生迁移,Cr、Hg不发生迁移。
To explore the content and health risks of heavy metal elements in soil and naked oats in Zhangbei area of Hebei Province,17 suitable sampling points were selected to collect surface soil and naked oats seed samples,and the single pollution index method,comprehensive pollution index and bioconcentration factors were used to study soil quality and migration ability of heavy metals from soil to naked oats in Zhangbei area of Hebei Province.The results showed that the content of heavy metals in the soil and naked oats in the study area was far lower than the national standard,the quality was safe and healthy.The enrichment ability of heavy metal elements in the soil-naked oats system in the area was Zn>Cu>Ni>Cd>As>Pb>Cr=Hg.The enrichment coefficients of Ni,Cu and Zn were much higher than those of Cr,As,Cd,Hg and Pb,and the migration ability of Cd was very weak.As and Pb hardly migrate,Cr and Hg do not migrate.
