Publikováno v: Chemosphere. 162

Experiments investigated irreversibility in pesticide sorption to soil. Sorption behaviour under abiotic conditions was quantified for chlorotoluron, prometryn and hexaconazole in three soils over periods of up to 274 days. An isotope-exchange proced

Pesticide sorption behavior is a complex process. The importance of extremely slow retention and release has superseded the notion that sorption of pesticides to soil is an instantaneous and reversible process. A fraction of sorbed pesticide is also

Transport of ions in physically heterogeneous systems; convection and diffusion in a column filled with alginate gel beads, predicted by a two-region model

An experimental flow system was developed to simulate solute transport in heterogeneous porous media, in which physical nonequilibrium occurs. The system consists of a column filled with spherical alginate gel beads. The gel acts as a stagnant water

Acceptability of inversely-modelled parameters for non-equilibrium sorption of pesticides in soil

Simulation of the increase of sorption in time is one of the options in higher tiers of pesticide regulatory leaching assessments to obtain more realistic leaching estimates. Therefore, accurate estimates of non-equilibrium sorption parameters are re

This study investigates time-dependent sorption of pesticides in soil aggregates. We tested if the sorption kinetics of pesticides in soil aggregates can be described by modeling diffusion into aggregates for a range of soils and pesticides. Our hypo

Modeling transport of protons and calcium ions in an alginate gel bead system : The effects of physical non-equilibrium and non-linear competitive sorption

Solute transport in heterogeneous soil systems is determined by a combination of physical and chemical processes. Heterogeneity can cause physical nonequilibrium, which results in asymmetrical breakthrough curves with early initial breakthrough and t
