| 摘 要： | 为摸清我国主产烟区的烟田灌溉水中的重金属含量情况,从全国五大烟区的13个主要植烟省的种烟县市采集了151个灌溉水样,其中河渠水样111个,降雨水样14个,水库水样5个,地下水样21个,测定分析了其重金属Hg、As、Cd、Cr、Cu、Pb的含量。结果表明:我国主要烟区灌溉水中重金属含量Hg含量为0(未检出,下同)~0.61μg/L,平均为0.17μg/L;As含量为0~8.16μg/L,平均为0.98μg/L;Cd含量为0~0.58μg/L,平均为0.03μg/L;Cr含量为0~7.29μg/L,平均为0.46μg/L;Cu含量为0~7.50μg/L,平均为1.54μg/L;Pb含量为0~10.13μg/L,平均为2.60μg/L。均低于相应的国家限量标准。水库水样综合质量指数最高,为0.20,北方烟区灌溉水样综合质量指数最高,为0.18。综合来看,我国烟区灌溉水环境质量目前均处于清洁水平。

| Abstract: | In order to understand the backgrounds of heavy metal contents in tobacco irrigation water in China, 151 irrigation water samples included 111, 14,5 and 21 were river and canal water, rain water, reservoir water and groundwater ones were collected from 26 tobacco-planting regions in 13 provinces, and the contents of heavy metals of Hg, As and Cd, Cr, Cu and Pb were measured. The results showed that the content of Hg was 0-0.61 u g/L with an average of 0.17 u g/L; the content of As was 0-8.16 u g/L with an average of 0.98 u g/L; the content of Cd was ND-0.58 u g/L with an average of 0.03 u g/L; the content of Cr was 0-7.29 u g/Lwith an average of 0.46 u g/L; the content of Cu was 0-7.50 u g/L with an average of 1.54 u g/L and the content of Pb was 0-10.13 u g/L with an average of 2.60 u g/L, which were all lower than the corresponding national limitations; The comprehensive water quality index of reservoir was the highest, which was about 0.20; The comprehensive quality index of irrigation water of north China was the highest, which is 0.18. In summary, the environment quality of tobacco irrigation water in China now was at the clean level. |
