Evaluation of Heavy Metal Pollutants From Plateau Mines in Wetland Surface Deposits

The Liupanshui Minghu Wetland is a typical artificial urban wetland in plateau mining region. It important to identify the sources and potential ecological risks of heavy metal contaminants its surface sediments monitor downstream water quality prevent pollution. In this study, we measured concentrations six toxic metals (Pb, Zn, Cr, Cu, Ni, Cd) collected from Wetland. Further, geological accumulation indices their risk indices, pollution levels, associated hazards were evaluated. average levels Pb, Cd superficial 197, 222, 79.0, 59.1, 68.6, 4.67 mg/kg, respectively. With exception remaining greater than background Statistical analysis indicated strong correlation between Cu ( p < 0.01). by these elements can be attributed human activities such as transportation, industrial activity, agricultural production. Ni activities, coal mining, natural phenomena, weathering mountains rocks. low minimal contamination. Pb moderately enriched, contamination ranged moderate high. Shiyuan region (S) was highest among three regions park. followed Longtoutan (L) region, lowest Erdaoba (E) Among metals, main contributor This study also strives provide theoretical basis data support for prevention control wetlands Alpine areas.
