A study was carried out in order to investigate the indoor exposure to permethrin, in rooms containing wool textile floor coverings. In 80 private homes with wool rugs and wool wall-to-wall carpets, the concentration of permethrin was monitored in wool fibres, in house dust and on airborne particles. The concentrations of permethrin in wool fibres varied from < 1 to 245 mg permethrin/kg wool fibre. The permethrin concentrations in house dust ranged from < 1 to 659 mg/kg. Permethrin was found in very low concentrations on airborne particles. Independent on the permethrin concen trations in house dust, in most cases the concentrations varied between < 1 and 6 ng/m3. The observed statistical correlations indicate that the indoor air permethrin level may be caused by a small fraction of wool fibres which are suspended in the air.
