The aim of this study was to investigate the pollution status of heavy metals in snails and evaluate their safety, to provide a reference for scientific evaluation of snails safety. The contents of Pb, As, Hg, Cd, Cr in snails were determined by ICP-MS, and the results were analyzed by correlation analysis, cluster analysis, principal component analysis and orthogonal partial least-squares discrimination analysis. The safety of snails was evaluated by single factor pollution index and Nemerow comprehensive pollution index. The results showed that the average contents of Pb, As, Hg, Cd, Cr in snails were 0.18, 0.03, 0.01, 0.01, 0.20 mg/kg respectively. Significant positive correlations were found between Pb and As, while the others were not. Cluster analysis, principal component analysis and orthogonal partial least-squares discrimination analysis all could separate snail production areas and screen out characteristic elements. The single factor pollution index of heavy metal elements in each producing area ranged from 0 to 0.50, and the Nemerow comprehensive pollution index ranged from 0.15 to 0.37. The evaluation grades were all safety grades. The snails were less polluted by heavy metals and had a high safety level, which suggested that the relevant departments should continue to strengthen the monitoring of heavy metals in snails to ensure their safety. The pollution of heavy metals in the snail was investigated and its safety was evaluated in order to provide a reference for the scientific evaluation of the edible safety of the snail.
