Survey of Dioxin Emission from PCP-treated Wood


Dioxin has been analysed in PCP-preserved construction wood from Danish family houses from 1960-1072. All samples contained dioxin. Levels of 84-1097 ng I-TEQ/kg wood wer observed. PCP and dioxin in single-use pallets imported with goods from South Europe has also been determined. PCP was registered in 6 out of 10 samples. The sample with the highest level of PCP contained 4,6 ng I-TEQ/kg wood. The emission of dioxin to air in Denmark from PCP-preserved wood is re-estimated at 0,23 - 9,9 g I-TEQ/year.
