摘要: 进入环境的活性X-3B红染料是一典型的持久性有机污染物(POPs).它从水分室向土壤分室再到作物分室的迁移,是一连续的生态过程.基于此,从理论上对活性X-3B红染料在水土壤两相、土壤作物两相以及水土壤作物整个连续体中的迁移进行了定量描述与探讨,并采用棕壤大豆、褐土小麦、红壤萝卜和水稻土水稻等系统给予了实验论证,表明活性X-3B红染料通过吸附机制从水分室到土壤分室的迁移符合Langmuir模型,通过作物根系吸收机制从土壤分室到作物分室的迁移可以用对数化的作物土壤积累因子(CSAF)模型予以定量描述.

Abstract: Reactive X-3B red dye entering into environment is a typical persistent organic pollutant(POPs).Transport of the dye from water to soil and from soil to crop compartment is a continuous ecological process.According to the cognitionm,the quantitative depiction of the process using mathematical models was theoetically discussed.Some of the mathematical models were also verified using burozem-soybean,cinnamon soil-wheat,krasnozem-radish,aquorizem-rice systems.In particular,transference of the dye from water compartment to soil compartment by way of adsorbent mechanisms was accorded with the Langmuir model,and movement of the dye from soil compartment to crop compartment on the basis of root-absorbing mechanisms could be expressed using logarithmic crop-soil accumulation factor(CSAF) models.

Key words: Reactive X-3B red dye, Transporting model, Water-soil-crop continuum, Pollution
