Popis:	(...) Oxamyl was found not to adsorb on PE and PVC, and etridiazole, not on PVC. A substantial amount of etridiazole was adsorbed by PE. Equilibrium is reached after 4 h. Equilibrium concentrations after adsorption and desorption could be described quantitatively by Freundlich's adsorption isotherm. The results obtained can be used to adjust the effective dosage of the fungicide. They may also contribute to assessment of environmental risks when plastic materials containing residual amounts of fungicide are discarded
