Abstract:

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.

Key words: atrazine, degradation products, soil, adsorption, degradation, leaching
