Abstract:

Atrazine, as a herbicide, can cause pollution to soil, groundwater, rivers and lakes while increase crop yield. Although atrazine is less toxic, it affects crop yield and constrains the development of sustainable agriculture in China because it is soluble in water, difficult to degrade and has more residues. This paper summarized the hazards to local flora and fauna caused by excessive atrazine residues, the threat to the ecological environment, and the impact on human health. The adsorption mechanism and residual causes of atrazine were reported, the effects on plants and animals were described. The existing atrazine degradation methods were compared and analyzed, and the future trends of atrazine degradation research were discussed. To solve the problems of long cycle of bioremediation technology, constructive suggestions were put forward in combination with different degradation methods. By combining physical repair technology, bioremediation technology and chemical repair technology, we aim to find out the repair technology that can degrade atrazine residues best and be conducive to the sustainable development.

Key words: herbicide, atrazine, degradation, residue, bioremediation, adsorption characteristics
