摘要
Abstract
Humic substances,a mixture of organic macromolecules,are widely exist in aquatic systems,soil and sediment.It can react with organic pesticides in the environment,and play significant roles in altering many physical and biogeochemical processes of organic pesticides in the environment.As a result,the behaviors of migration and transformation,eco-toxicity and bioavailability of the organic pesticides are dramatically changed.In this paper,the adsorption mechanisms between humic substances and organic pesticides were summarized and discussed.It focused on the formation conditions,affecting factors,formation processes and characteristics of the ionic bond,covalent bond,hydrogen bond,van der waals,ligand exchange,hydrophobicity distribution,electron transfer and so on.Finally,some further research directions and emphasis on the interaction mechanisms between the humic substances and organic pesticides were proposed.关键词
