The extraction and processing of ores from lead-zinc mines, coupled with the disposal of tailings, often result in severe environmental contamination that poses significant ecological and public health risks, demanding urgent attention and action. In this study, field investigations and analyses were performed to evaluate the state of heavy metal pollution and microbial diversity in the soil around Qixia Mountain lead-zinc mine in Nanjing, China. The effect of plant-/microorganism-induced mineralization on the remediation of the contaminated soil was studied pot experiments. Results indicated serious soil pollution around the mine, and dominant bacterial species () in different soil environments exhibited high resistance to heavy metals. Pot experiments showed that amaranth-/-induced mineralization can significantly reduce the heavy metal pollution levels (Nemerow pollution index decreased from 4.5 to about 1.0) in soil. This study reveals the profound impacts of mining activities on soil ecology and human health, providing a theoretical basis for the prevention and control of soil pollution in farmlands surrounding lead-zinc mines.
铅锌矿的矿石开采与加工，再加上尾矿的处置，常常导致严重的环境污染，带来重大的生态和公共健康风险，亟需关注和采取行动。在本研究中，开展了实地调查与分析，以评估中国南京栖霞山铅锌矿周边土壤中的重金属污染状况和微生物多样性。通过盆栽试验研究了植物/微生物诱导矿化对污染土壤修复的影响。结果表明矿区周边土壤污染严重，不同土壤环境中的优势细菌物种对重金属表现出高抗性。盆栽试验表明，苋菜/微生物诱导矿化可显著降低土壤中的重金属污染水平（内梅罗污染指数从4.5降至约1.0）。本研究揭示了采矿活动对土壤生态和人类健康的深远影响，为铅锌矿周边农田土壤污染的防治提供了理论依据。
