2017年哈尔滨市主要地产食用农产品铅镉污染调查分析

Research and Analysis of Lead and Cadmium Pollution in Major Local Edible Agricultural Products of Harbin in 2017

为监测哈尔滨市主要农产品铅和镉重金属污染的状况,探究污染的来源,为政府相关决策提供科学的理论依据。于2017年6月和9月在严格的质量控制下,按照统一的方法,共采集6大类471件地产食用农产品和淡水鱼样品,进行了重金属铅和镉2个指标的监测。结果表明:在获得的837个有效数据中,2件蔬菜镉含量超标,其余样品中铅和镉含量均低于国家限量标准。哈尔滨市农产品和淡水鱼受铅和镉重金属污染风险较少,有少量农产品受到镉重金属污染,污染可能来源于农产品生产过程的投入品,如肥料、农药、灌溉水等、城市垃圾和工业废水等。应加强对产地环境的综合治理。
