| 中文摘要: |
| 遵义市植烟土壤中存在重金属污染，而烟草重金属主要来源于土壤、施肥、大气沉降及降雨或灌溉等途径。因此，本文针对可能会引起遵义市烟草重金属污染的来源，包括施肥和灌溉2种途径进行调查研究。集中采集了遵义市余庆县、凤冈县、湄潭县、务川县、仁怀县、遵义县、桐梓县及道真县8个县市主要种植烟区的572个灌溉水样和21个有机肥肥料样品，通过进一步分析及测定样品中重金属As、Cd、Cr和Pb含量，并与国家相应标准进行了对比。结果表明：灌溉水中重金属As、Cd、Cr、Pb的含量分别为国家限量标准《农田灌溉水质标准（GB 5084—2005）》的0~71%、0~2.9%、0~6.6%和0~8.5%。肥料中重金属As、Cd、Cr、Pb的含量分别为国家限量标准《中华人民共和国农业行业标准（NY 525—2012） -有机肥料》的3.87%～64.1%、2.33%～74.7%、6.53%～38.1%和10.9%～59.2%。调查结果表明，目前遵义主要植烟区灌溉水和肥料中重金属含量均不超标，属于安全级别，因此排除了该区域烟草重金属来源于施肥及灌溉两种途径的可能性。 |
| 英文摘要: |
| In order to examine the exogenous situation of heavy metals in tobacco growing areas of Zunyi City, irrigation water samples(n=572) and organic fertilizer samples(n=21) were collected from the main tobacco growing areas. The concentration of As, Cd, Cr and Pb were investigated and compared with the national standards. The results showed that the concentration of As, Cd, Cr and Pb in the irrigation water were 0~71%, 0~2.9%, 0~6.6% and 0~8.5% of the national standard respectively. The concentration of As, Cd, Cr and Pb in fertilizers were 3.87%~64.1%, 2.33%~74.7%, 6.53%~38.1% and 10.9%~59.2% of the national standard respectively. The concentration of heavy metals in irrigation water and organic fertilizer in the main tobacco growing areas of Zunyi City is at the safe level. |
