In order to explore the status of soil heavy metal pollution and environmental quality in west Hunan, relevant areas of Phoenix County were selected as the study area. Using data from 440 soil samples collected in the study area from June to August 2022, the pH value of the soil and contents of eight heavy metal elements, namely, As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn, were analyzed. The PMF model was used for traceability analysis and geochemical evaluation of soil environmental quality.

- The study investigates the impact of soil parent materials on cadmium (Cd) levels in crops, particularly maize, in karst areas.
- The researchers found that soils from alluvial materials had less total Cd but higher bioavailability, leading to higher Cd concentrations in maize.
- Using advanced prediction models, they proposed improved strategies for the safe use of arable land, ensuring crop safety while considering soil properties and Cd levels.
Based on the grid distribution method, 1589 topsoil samples were collected from farmland on the south side of Dongting Lake from April to August 2020. The content, potential ecological risk, spatial distribution characteristics, and source analysis of heavy metals in the soil were studied. The concentrations and pH of As, Cd, Pb, Cu, Zn, Ni, Cr, and Hg in the soil were determined using ICP-MS, ICP-OES, HG-AFS, and ISE methods.
