摘　　要：金属硫化物在土壤中的存在及其迁移转化过程对环境质量、生态安全和人类健康构成了潜在威胁。这些化合物主要来源于自然过程(如岩石风化、地质活动和微生物作用)及人为活动(包括矿产开采、工业生产和农业活动),其在土壤中的迁移转化受多重因素影响,如土壤的物理化学属性、气候条件及微生物活动,这些因素共同决定了金属硫化物的生物可利用性和毒性。未来研究应深入探索金属硫化物的微观交互机制及环境变化下的长期效应,并通过跨学科研究为土壤中金属硫化物污染提供有效解决策略。The presence and transformation process of metal sulfides in soil pose potential threats to environmental quality,ecological safety,and human health.These compounds primarily originate from natural processes such as rock weathering,geological activities,and microbial actions,and human activities including mining,industrial production,and agricultural practices.Their behavior and transformation in soil are influenced by multiple factors,such as the physicochemical proper-ties of the soil,climatic conditions,and microbial activities,which together determine the bioavailability and toxicity of metal sulfides.Microbial influences on the formation and decomposition of metal sulfides,along with abiotic factors such as climate change,soil pH,and redox conditions,significantly affect their migration and transformation rates.Future research should delve deeper into the micro-interactions of metal sulfides in soil and the long-term effects under environmental changes,while interdisciplinary achievements will provide effective strategies for addressing pollution issues related to metal sulfides in soil.
