Abstract

In this study, the soil and walnut samples were taken in the main walnut producing area of Tianjin, and the content characteristics of heavy metals Cd, Hg, Pb, As, Cr, Zn and Cu in the soil were analyzed. Three methods were used to evaluate soil environmental quality in the study area, i.e., Nemerow index method, geo-accumulation index method and pollution load index.The safety of walnut samples was analyzed. The results show that the average values of Cd, Hg, Pb, As, Cr, Zn and Cu in the soil samples are 0.19×10^-6, 0.06×10^-6, 24.1×10^-6, 11.9×10^-6, 75.5×10^-6, 78.9×10^-6 and 30.6×10^-6, respectively. The average values of Cd, Hg, As and Cu exceed the background values of Tianjin, and 11.7% and 1.7% of the samples of Cd and Cu exceed the risk screening values. For the single evaluation results, Nemerow single index method shows that 10.0% of the samples of Cd have slight pollution, 1.7% of the samples have moderate pollution, and 1.7% of the samples of Cu have slight pollution. According to the method of Nemerow comprehensive index, the soil environmental quality of the study area is generally better, but according to the evaluation results of geo-accumulation index and pollution load index, it can be found that there is heavy metal accumulation caused by human factors in the study area, and the pollution points are evenly distributed in the study area. The average values of Cd, Hg, Pb, As and Cr in walnut samples are 0.003 ×10^-6, 0.004 ×10^-6, 0.044 ×10^-6, 0.043 ×10^-6 and 0.760 ×10^-6, respectively, which meet the requirements of food safety standards.
