The dependence of bats in Britain on houses as roosts may result in them being exposed to pesticides used in remedial timber treatments. Pentachlorophenol (PCP) and permethrin are used as a fungicide and an insecticide for timber treatment, respectively. The present study investigated toxicity and distribution in body tissues of these two pesticides in pipistrelle bats. Four groups of nine to ten bats were kept in separate outdoor flight enclosures and were provided with roost boxes treated with either PCP only, permethrin, PCP/permethrin mixture or solvent only (control). At the start of the experiment, mean (+/-SE) PCP and permethrin concentrations on the surface of wooden blocks that had been treated in the same way as roost boxes were 69.32+/-6.76 mg g(-1) (n=6) and 3.3+/-1.6 mg g(-1) (n=3), respectively. All bats exposed to PCP and PCP/permethrin treated boxes died within 24 and 120 h, respectively; nine out of the ten controls survived the 32 day experimental period (P<0.001; both groups compared with control). Bats exposed to permethrin treated boxes survived as well as controls. Mean (+/-SE) carcass PCP concentration (excluding deposits on fur) of bats exposed to PCP and PCP/permethrin treated boxes was 13.11+/-2.52 microg g(-1)BW (n=20). PCP burdens on fur were positively correlated with total weight of PCP in the carcass (P<0.001). PCP was present in fat depots, liver, kidney and the remainder of the body which, despite containing low PCP concentrations, was the main PCP reservoir (66.4+/-5.0% of carcass PCP load; n=20). Total PCP in the carcass was significantly correlated with lipid weight (P<0.005). Permethrin was not detectable in body washes and tissues of bats exposed to PCP/permethrin mixture or permethrin.
