摘要: 本研究根据调查区域内食用林产品资源分布特点,选取A、B、C等地,以特色食用林产品核桃、花椒和竹笋为研究对象,对其产品及各区域森林土壤进行抽样调查,分析该区域食用林产品质量安全因子的风险。结果表明,抽样核桃几乎无农药残留,抽样花椒虽有农药残留但无超标,抽样鲜竹笋存在局部区域性农药喷洒过量,有部分超标;不同地区3种食用林产品样品各重金属指标含量有一定差异,这与各自生长区森林土壤中重金属含量有关联性,属部分矿区地质性因素造成。Abstract: In this study,according to the characteristic distribution area of edible forest product resources. Three regions (A, B, and C) were selected, and the characteristic edible forest products including walnuts,zanthoxylums and bamboo shoots were taken as research targets to carry out a sampling investigation on the products and forest soil,so that analysis was made of the risk of edible forest product quality safety factors. The results showed that:there were almost no pesticide residues in the walnut samples; the pesticide residues existed in the zanthoxylum samples but were under the standard; and the bamboo shoot samples were excessively sprayed with pesticides regionally, which were partly beyond standard. The heavy metal index contents of the three edible forest product samples in different areas had certain differences, which were relative to the heavy metal contents of their forest soil as a result of geological factors of some mining areas.
