摘要

为了研究河南烟区土壤和烤烟中As,Zn,Cr,Pb,Cu,Ni和Cd 7种重金属的状况,考察了河南4个主要烟区土壤及其所产烤烟中的重金属含量。采用内梅罗指数法对土壤污染水平进行评价,结果表明,河南91%烟区中的重金属状况属于安全等级,只有9%烟区的重金属情况属于尚清洁等级。采用富集倍数法考察了烤烟对各金属的富集情况,结果显示,烤烟对于As,Pb,Cr和Ni属于无富集植物,对于Zn和Cu属于轻微富集植物,只有对于Cd属于中度富集植物。比较4个烟区烤烟发现,许昌烟区和平顶山烟区烤烟富集系数整体较低,但Cd富集系数偏高;而三门峡烟区和洛阳烟区烤烟的富集系数整体偏高。进一步考察烤烟中各金属含量与所种植的土壤中重金属的相关性,结果表明,烤烟中的重金属含量与土壤中该重金属含量呈显著正相关,说明土壤中重金属元素是烤烟中重金属元素的重要来源。
        In order to study the pollution status of seven heavy metals( As,Zn,Cr,Pb,Cu Ni and Cd) in soil and flue-cured tobacco in Henan province,the contents of heavy metals in soils and tobacco of four major tobacco-planting areas in Henan province were investigated. The Nemerow index method was used to evaluate the level of soil pollution. The results showed that 91% of the Henan tobacco area belonged to safety level,while only 9% of the sampling sites belonged to clean level.Based on analysis of the enrichment of heavy metals in tobacco studied by bioconcentration factor( BCF) method,the results indicated that tobacco belonged to non-enrichment plants for As,Pb,Cr and Ni, slightly enrichment plants for Zn and Cu, and moderately enrichment plants for Cd.Comparing in the four tobacco areas. It was also found that the BCF of flue-cured tobacco in Xuchang and Pingdingshan was lower,but the BCF of Cd was higher,while the BCF of flue-cured tobacco in Sanmenxia and Luoyang was high. Furthermore,the correlation relation between the contents of metals in flue-cured tobacco and the contents of heavy metals in soils showed that revealed that the content of heavy metals has a positive correlation in the tobacco and soil,which suggested the metal elements in soils were important sources for the flue-cured tobacco.
