| 초록 | The time evolution of extractable remaining pesticides shows generally two time scales while they are decomposed. It could be interpreted as that initial pulse input ofpesticide begins to decompose as well as to change its state into that of bound-residueand once pulse input decays and bound-residue develops, bound-residue changes itsstate into the decomposable pesticide and finally decomposes. We suggest a kineticmodel that can qualitatively and quantitatively explain the decomposition of pesticideand the shift of its vulnerable state against microbe’s attack, soil catalytic activity, orother possible decomposition activity. At very low concentration of pesticide, ourmodel reduces to Hamaker and Goring’s model and the effect of model-inducednonlinearity diminishes. The kinetic rate constants of each pesticide in paddy and uplandsoil are statistically determined, using Kirkpatrick’s simulated annealing method tosearch the global minima. |
