抚州市烟叶及其产区环境质量安全状况分析

摘要

To research the safety status of tobacco leaves and environmental security in Fuzhou City,sulfur dioxide,nitrogen oxides,total suspended particular,fluoride,Pb in the atmosphere,the heavy metal and pesticide residues content of tobacco growing areas,irrigation water and cured tobacco leaves were used as samples for analysis.The results showed quality of ambient air,tobacco growing areas and irrigation water agreed with the standards for pollution-free food production.The heavy metal content in cured tobacco leaves and tobacco growing areas had no close relationship.The heavy metal content in tobacco leaves was mainly from the course of tobacco production.The contents of Cr,Cu,Ni and Pb in tobacco growing areas were significantly increased in the course of tobacco production.There were residual butralin,residual pendimethalin,residual propamocarb hydrochloride and residual diphenamide pesticides in cured tobacco leaves,so it should be controlled strictly during production.%为研究抚州烟区烟叶及其产区环境质量安全状况，对产区大气中二氧化硫、氮氧化物、总悬浮物颗粒物、氟化物、铅，植烟土壤、灌溉水、产后烟叶中的重金属、农残等有害物质进行取样分析。结果表明，抚州烟区环境空气、植烟土壤、灌溉水质量符合无公害农产品生产的产地环境条件；产后烟叶中重金属含量与植烟土壤中的重金属含量相关性不强，烟叶中的重金属主要来源于烟叶生产过程；烟叶生产能显著提高植烟土壤中铬、铜、镍、铅的含量；产后烟叶中仲丁灵、二甲戊灵、霜霉威、双苯酰草胺有一定残留，在生产中应加强管控。
