The dissipation and persistence of two cereals herbicides, chlorotoluron and flufenacet,
were studied in a field experiment including three replicated plots of unamended soil (S) …

Effective prediction of pesticide fate using mathematical models requires good process
descriptions in the models and good choice of parameter values by the user. This paper …

The influence of fly ash on the adsorption and desorption of four selected chlorophenols and
two herbicides has been studied in mixtures with a sandy clay loam (SCL) soil. Fly ash and …

Metribuzin degradation rate was determined in three soils by laboratory experiments under
controlled conditions. Degradation in all soils closely approximates first order kinetics …

SUMMARY A study on simazine and hexazinone persistence in soil was performed under
field and laboratory conditions. The laboratory assay showed an increase of the degradation …

Many pesticide fate and transport models, including the GLEAMS model, overestimate
pesticide degradation during its later stages of residence in soil. Except for runoff events …

Laboratory and field experiments were carried out on a loam soil and a sandy loam soil to
study the persistence of metolachlor, atrazine and deethylatrazine in soil under Spanish …

In the following review, papers considering fate and transport processes in groundwater
systems are discussed first. The fate and transport process papers are divided among …

Tu (1994) investigated the effects of 14 insecticides on mi crobial activities related to soil
fertility. The insecticides did not inhibit the ammonification and sulfur oxidation of the agricul …

Se ha estudiado el comportamiento ambiental en los herbicidas terbutilazina, terbacil,
molinato y tiobencarb. Los resultados obtenidos indican que la terbutilazina y el terbacil se …
