[Advances in researches of environmental behavior of sulfonylurea herbicides in soil].
In this article, the environmental behavior of sulfonylurea herbicides in soil, which included absorption and de-sorption, degradation, resistance, mobility, and inhibition on soil enzyme activity, was reviewed, and the influences of some soil factors, such as pH, soil type, water content, and organic matter on their environmental behavior were also discussed. Distributed Reactivity Model for Sorption was used to explain the hysteretic behavior of sulfonylurea in soil, and the biotic and abiotic degradation mechanisms were summarized. Some prospects on their ecological toxicity, adsorption strength, and degradation model were also discussed.
