Pentachlorophenol exposure through indoor use of wood preservatives in the Federal Republic of Germany
AbstractUntil 1977, wood preservative formulations containing pentachlorophenol (PCP) and lindane were freely used for domestic purposes in the Federal Republic of Germany. In 90% of the 217 households examined, such formulations were applied, and the quantity used per house varied from 25 to 1000 g for lindane and 50 g to 10 kg for PCP (commercial grade). The median concentration of PCP in urine was 29 μ/L for the group exposed to wood preservatives, as compared to 10 μg/L in the nonexposed group. Indoor air samples from 104 examined households showed a median level of 5 μg PCP/m3. Dust samples collected using vacuum cleaners in households where wood preservatives had been applied showed a median value of 13 μg PCP/g, as compared to only 0.008 μg PCP/g in samples from the control group. PCP concentration in indoor dust samples corresponded well with urinary PCP levels. In 250 persons who showed a relatively high exposure, additional clinical investigations were made, and in spite of elevated urinary PCP levels, no abnormalities were detected. In some cases, the exposure to PCP was followed up for a longer period, and even seven years after the wood treatment, higher urinary PCP levels recorded provided evidence of a continued exposure to wood preservatives. Now, due to the efforts of the German Federal Health Office, the use and production of PCP has been banned in the country since August 1987.
