Research on the Risk Analysis of Edible Forest Product Quality Safety Factors in Sichuan Areas

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.
