摘　　要：为了解我国金银花主产区花和土壤重金属污染情况以及暴露风险,本试验对我国三大主产区(山东平邑、河南封丘、河北巨鹿)的金银花和土壤进行取样调查,测定了金银花和土壤中Pb、Cr、Ni、Cu、Zn、As、Hg、Cd、Mn元素含量,分析了这9种元素在金银花及其生长土壤中的分布和相关性,并对土壤重金属的污染情况进行了地质累计指数、潜在生态风险和健康风险评价。结果表明,土壤中Cd和Cu元素的含量大多高于当地土壤背景值,而其他元素的含量大多低于当地土壤背景值;各元素含量均未超出农用地土壤污染风险管制值。金银花对土壤中不同元素的富集能力不同,不同产地金银花对相同元素的富集能力也存在差异。金银花对土壤中各元素富集系数的趋势为As<Mn<Pb<Cr<Ni<Zn<Hg<Cu<Cd。除Cd元素外,其他8种元素Pb、Cr、Ni、Cu、Zn、As、Hg和Mn均未对金银花主产区土壤造成污染。金银花主产区土壤重金属的生态风险总体处于低风险水平,金银花土壤中重金属经口摄入、皮肤接触和呼吸途径进入人体的风险较低。本研究为金银花产业健康发展提供了一定的科学依据。To understand the pollution situation and exposure risk of heavy metal to honeysuckle(Lonicera japonica Thunb)and soil from main producing area,the honeysuckle and soil sample were colected from the three main producing areas(Fengqiu county in Henan province,Pingyi county in Shandong province,and Julu county in Hebei province).The contents of 9 elements Pb,Cr,Ni,Cu,Zn,As,Hg,Cd,and Mn in honeysuckle and soil were determined.The distribution and correlation of 9 elements between honeysuckle and its growing soil were analyzed,and the heavy metal pollution of soil ware evaluated by geological accumulation index,potential ecological risk,and health risk assessment.The results indicated that the contents of Cd and Cu in soil were higher than the local soil background,and the contents of other elements were lower than the local soil background.The content of each element did not exceed the risk control value of soil pollution in agricultural land.The enrichment ability of honeysuckle to different elements in soil was different,and the enrichment ability of honeysuckle from different producing areas to the same element was also different.The trend of honeysuckle on the enrichment coefficient of each element in soil was As<Mn<Pb<Cr<Ni<Zn<Hg<Cu<Cd.With the exception of Cd,the other 8 elements Pb,Cr,As,Hg,Ni,Mn,Cu,and Zn did not pollute the soil in the main producing areas of honeysuckle.The ecological risk of heavy metals in the soil from the main honeysuckle producing area was generally at a low risk level.The health risk of heavy metals from honeysuckle soil entering human body through oral ingestion,skin contact,and inhalation was low.This study provides a research basis for the healthy development of the honeysuckle industry.
