Popis: Government regulators of agricultural pesticides use multidisciplinary computer models with which they make product licencing decisions. Hydrology engineering and chemistry components are integrated into the multidisciplinary models. Although the scientific quality of the hydrology components is reasonably good, the scientific quality of the chemistry component does not match this good quality. These models often use chemically meaningless parameters and assumptions that are not supported by experiments. During the past 25 years chemical kinetics and mechanisms based on experiments and stoichiometry have been published for most agricultural pesticides in soil and water. Thus, the chemistry components should now be replaced with those that use the kinetics and mechanisms currently available. They should next be continuously upgraded as the chemical mechanisms research evolves.
