Heavy metal pollution and risk assessment of farmland soil in eco-tourism resort

In order to understand the heavy metal pollution and risk status of eco-tourism resort, the geological accumulation index method, potential ecological hazard index method, and health risk assessment model were used to evaluate the soil heavy metal pollution degree, ecological risk, and health risk of ecotourism resorts in China. Except for Ni, the other seven heavy metals in the study area were polluted to varying degrees, and the main heavy metal pollutant Cr increased significantly in the region, mainly concentrated in the areas where human life is relatively concentrated. The risk index of Cd was the highest, ranging from 11.50 to 356.5. The average value of non-carcinogenic health risk index of heavy metals in children and adults was 1.53 and 0.233, respectively, and the maximum value was 6.34 and 1.04, respectively. The results showed that the soil pollution in the study area was serious and the ecological risk level was very strong, which constituted non-carcinogenic risk to children and adults.
