根据近年农药环境毒理学的研究结果 ,介绍了在不同条件下农药在环境中降解的四个数学模型。其中得到广泛应用的是指数模型C=Coe- Kt;当前后期农药降解速度不同时可用 C=Ae-αt+Be-βt双室模型表达 ;用一级吸收模型 C=A( e-αt-e-β t)可以表达具有吸收和降解双过程的农药动态变化 ,多次施药时可用模型 ( Cn) t=C01 -e- n KL1 -e- KL e- kt表达
According to the results of the research on environmental toxicology of pesticides in recent years, four mathematical models of the degradation of pesticides in the environment under different conditions are introduced. Among them, the exponential model C = Coe-Kt is widely used; when the degradation rates of the late pesticides are different, C = Ae-αt + Be-βt can be expressed in two- -β t) can express the dynamic changes of pesticides with dual processes of absorption and degradation. The model can be expressed in multiple models (Cn) t = C01 -e-n KL1 -e-KL e-kt
