地下水中有机质对碘迁移转化的影响
|
Abstract:
地下水中有机质的存在对碘的迁移和转化过程有着重要影响。碘在环境中是一种重要的微量元素，广泛存在于水体、土壤和生物体中，其迁移行为和转化机制直接影响生态系统的平衡及人类健康。本文根据过往研究，探讨了碘在环境中的分布与形态以及碘在地下水中的迁移转化机制，总结了地下水中有机质在碘的物理化学行为中所起的作用，分析了有机质种类、浓度、结构特征等因素对碘迁移和转化的影响。同时，本文综述了有机质与碘的相互作用机制及其对地下水中碘污染的潜在影响，为评估地下水中碘的环境风险及制定相关治理措施提供理论依据。
The existence of organic matter in groundwater plays an important role in the migration and transformation of iodine. Iodine is an important trace element in the environment, widely existing in water, soil and organisms, and its migration behavior and transformation mechanism directly affect the balance of ecosystem and human health. Based on previous studies, this paper discussed the distribution and form of iodine in the environment and the migration and transformation mechanism of iodine in groundwater, summarized the role of organic matter in the physical and chemical behavior of iodine in groundwater, and analyzed the influence of organic matter types, concentrations, structural characteristics and other factors on the migration and transformation of iodine. At the same time, the interaction mechanism of organic matter and iodine and its potential impact on iodine pollution in groundwater were reviewed, which provided a theoretical basis for assessing the environmental risk of iodine in groundwater and formulating relevant control measures.
