有毒有害化学品多元复合体系的多介质环境行为研究

Combining with the field estimation, laboratory simulation, and mathematical modeling.methods, the systematic research on the multi-media and multi-interfacial environmental behavior of.complex-pollution system consisted of insecticide aldicarb or herbicides acetochlor and butachlor with.surfactant, humic substance, inorganic nitrogen etc which performs in the eco-system including soil,.groundwater, crop and microorganism has been conducted. The distribution of main pollutants in this.eco-system has been demonstrated, and a series of phenomena involved of solution enhancement,.leaching, adsorption/desorption, biodegradation, hydrolysis, photolysis, intake and digestion by crop,.influence upon groundwater, and ecotoxicological effects and so on multiple non-homogeneous.physicochemical and microbiological reaction mechanisms have been detailed studied; some complex.effects between pollutants each other, pollutants with natural substance were clarified; The multi-media.dynamic models which could be describe the movement of pollutants performed in the open.eco-system have also established. The preliminary theoretical foundation provided here might.consulted for to hinder and remediate the soil pollution..The research’s result shown that: some new phenomena and certain rule have been discovered; main.portion of content have not seen in the published international and domestic literature.

通过研究典型有毒有害化学品－氨基甲酸酯杀虫剂和酰胺除草剂、表机活性剂及天然存在物质组成的复合体系在开放型陆生土壤环境多介质多界面中的分布、界面传输、重要非均相物理化学及微生物反应机理，建立动态多介质模型，为阻断和修复污染奠定理论基础；阐述多介质多界面系统的特性，并首次研究复合体系多介质问题，丰富多介质理论和建模方法学。.
