溶解性有机物的特征及对环境污染物的影响

摘要

溶解性有机物是由成分复杂的非均质混合物组成,在环境中分布广泛,具有较高的稳定性和生物难降解性,对有机物污染物和重金属在环境中的迁移转化、生物有效性和毒性等有重要影响,而且在水处理过程中可能转化成有毒副产物。本文综述了溶解性有机物的结构特征以及对环境污染物的影响。%Dissolved organic matter（DOM）,being ubiquitous in the environment,had various properties related to its origin,highly stable and microbially refractory properties.DOM not only played an important role in influencing microbial activity,degradation,transport and transformation,toxicity and bioavailability of trace metals and organic pollutants,but also can be potentially converted to toxic byproducts during treatment process.The structural characteristics of dissolved organic matter and the impact of environmental pollutants were reviewed.
