Environmental and urine sampling was conducted in 15 log homes in Montana previously treated with wood preservatives containing pentachlorophenol (87865) (PCP). The Montana Department of Health had requested assistance in evaluating exposures to PCP among state residents in PCP treated log homes. Skin and wood surface wipe samples were taken along with air samples. Urine samples were collected from all available residents. No airborne PCP was detected (less than 7 micrograms/cubic m) in any of the homes. Wipe samples of wood surfaces contained up to 380 nanograms/square centimeter (ng/cm2) PCP. No PCP was detected in skin wipe samples. The 23 potentially exposed residents had urine PCP concentrations ranging up to 35 micrograms PCP/gram creatinine (microg PCP/g Cre) with a mean of 12 microg PCP/g Cre. Seventeen urine samples from a control group ranged up to 11 microg PCP/g Cre with a mean of 4 microg/g Cre. The author concludes that there is no known health hazard due to PCP exposure in any of the homes studied. For homes with existing indoor PCP treated surfaces, the application of varnish or polyurethane sealers is recommended by the author to keep vaporization of PCP to a minimum. PCP treated materials should be kept out of reach of small children, and treated wood products should never be burned.
