Methods of reducing the amount of pediculocide residues on bed linens to safe levels

: The means for reducing the residue of organophosphorous and pyrethrin pediculicides on the fabric to safety levels have been developed due to the use of gas and liquid chromatography. The proposed procedures include linen washing after its pediculicidal treatment. Optimal conditions for the removal of the above substances from the fabric have been set forth. Actual quantity of pediculicides on the fabric after its treatment has been identified.
