- The highest concentrations were found in the upstream areas due to pollution from agriculture and livestock, while downstream pollution correlated with urban activities and economic growth.
- Risk assessments indicated varying ecological dangers, with specific antibiotics like ofloxacin and enrofloxacin posing high risks to both ecology and human health.
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.
