贵州山地特色农产品中铅与砷含量及污染评价

Lead and Arsenic Contents and Pollution Evaluation of Agricultural Products with Mountain Characteristics in Guizhou Province

  • 摘要: 为了解贵州山地特色农产品中铅与砷的污染状况,测定了贵州省主要种植基地的220个茶叶、350个薏苡仁、60个竹荪、150个辣椒、50个马铃薯及200个猕猴桃样品中铅与砷的含量,并对其进行了污染评价及风险分析。结果表明,茶叶、薏苡仁、竹荪、辣椒及马铃薯中铅的含量范围依次为:0.18~2.6、0.041~0.21、0.043~1.2、ND~0.093、ND~0.045 mg·kg-1;砷的含量范围依次为:ND~0.053、ND~0.044、0.068~1.1、ND~0.042、ND~0.041 mg·kg-1;贵州主要山地特色农产品中铅与砷的综合污染程度表现为:竹荪 > 辣椒 > 薏苡仁 > 茶叶 > 马铃薯 > 猕猴桃,其中茶叶、薏苡仁、辣椒、马铃薯及猕猴桃均属于清洁水平,安全等级,只有竹荪属于尚清洁水平,警戒等级,存在一定的健康风险;不同农产品对重金属的富集程度有较大差异,竹荪较其它农产品更易富集重金属。

     

    Abstract: In order to investigate the pollution status of lead and arsenic in the agriculture products with mountain characteristics in Guizhou province,the content of lead and arsenic were detected in 220 samples of teas,350 samples of coix seeds,60 samples of bamboo funguses,150 samples of peppers,50 samples of potatoes and 200 samples of kiwifruits from the planting base in Guizhou province,and the pollution evaluation and risk analysis were conducted. The results showed that the contents of lead in tea,coix seed,bamboo fungus,pepper and potato were 0.18~2.6,0.041~0.21,0.043~1.2,ND~0.093,ND~0.045 mg·kg-1.The contents of arsenic were ND~0.053,ND~0.044,0.068~1.1,ND~0.042,ND~0.041 mg·kg-1.The comprehensive pollution degree of lead and arsenic in the agriculture products with mountain characteristics in Guizhou province was shown as:Bamboo fungus > pepper > coix > seed > tea > potato > kiwifruit. Among them,tea,coix seed,pepper,potato and kiwifruit all belonged to the level of cleanliness and safety,only the bamboo fungus belonged to the level of cleanliness and alert,and there were some health risks. The content of heavy metals in different agriculture products were different,the content of heavy metals in the bamboo fungus were higher than others.
