Survey of Dioxin Emission from PCP-treated Wood
5 Results
5.1 PCP screening of pallet board samples
Table 5.1 shows the analysed concentrations of pentachlorophenol in the pallet board samples. All samples have only been
single-determined. The results show that 6 out of 10 samples contained pentachlorophenol. Sample number 2 from Portugal
had the highest concentration of pentachlorophenol, and the dioxin concentration in this sample was therefore afterwards
measured (see result in next section).
Table 5.1 shows that out of the 6 samples with a detected pentachlorophenol concentration, two of the samples came from
Spain; two came from France and two from Portugal. This means that both analysed samples from Portugal and 2 out of the
three samples from France were positive.
It should be noted that the concentration of PCP registered in the samples represents an average of the concentration over the
entire thickness of the individual samples.

5.2 Dioxin analysis of pallet board sample
Pallet board sample number 2 was analysed for dioxin, but as table 5.2 shows the dioxin concentration in the pallet board
sample is low. It is noted that only one analysis has been made, and the result may thus be regarded as an indication of the
dioxin level in these items rather than solid documentation.
As for PCP the concentration of dioxin registered in the sample represents an average of the concentration over the entire
thickness of the sample.

5.3 Construction-wood samples
The five samples of construction wood have been analysed for dioxin by single determination. The pentachlorophenol
concentration in the samples has not been analysed.
Table 5.3 shows the concentration of the different isomers measured and the total concentration of the dioxin isomers given in
ng I-TEQ/kg and in ng WHO-TEQ/kg.
The concentration of dioxin registered in the samples represents an average of the concentration over the entire thickness of the
individual samples.
