| Abstract: | In this paper,degradation pathways of pesticides,mainly for herbicides,and affected factors in aquatic systems was expounded.Firstly,mechanism of degradation for the pesticides in aqua is described.Generally,neutral bridge in carbonyl groups in pesticide molecular is attacked by OH-to form analogs with non-biological activity,releasing CO2.Affected factors for the degradation of the pesticides in aquatic media include: pH value,temperature and clay content in the aquatic system.We took both sulfuron-herbicides and imidacloprid insecticide as typical examples to describe pesticide degradation pathways on aquatic system. |
