阿特拉津的主要降解产物在土壤中转化与运移的研究进展

 阿特拉津是中国华北和东北地区玉米地常用的除草剂，它在土壤环境中的主要降解产物脱乙基阿特拉津和脱异丙基阿特拉津具有与其母体化合物类似的毒性，且极性高、易在土壤中运移。对阿特拉津的主要降解产物在土壤环境中的运移与转化规律开展定量研究，已受到环境科学和土壤科学领域的关注，但系统深入的研究尚不充分。本文较详细地介绍了阿特拉津的主要降解产物在土壤中的吸附、降解和淋溶方面的国内外研究进展，为国内的科研工作者开展与此相关的研究工作提供参考。

The Transformation and Transport of Main Degradation Products of Atrazine in Soils-A Review

Atrazine is an herbicide commonly used on summer maize in North and Northeast China, and deethylatrazine (DEA) and deisopropylatrazine (DIA), its two main metabolisms in soils, have similar toxicity with the parent compound, and have high polarity and mobility. In this review, the research progresses of the adsorption, degradation and leaching behaviors of the main metabolisms of atrazine in soils were summarized and analyzed in detail. It is shown that more recently, attention has been focused on the study of the transformation and transport of the two metabolisms of atrazine in soils, however, a systematic and quantitative study of the environmental fate of DEA and DIA in soils have not been carried out. This review will provide some references to the researchers on their studies.
