Abstract niet beschikbaar
This report describes the results of immission measurements for PCDD/F in an urban area in the South East of the Netherlands (Zuid-Limburg). Results of these measurements show that the average background concentration of polychlorodibenzo-p-dioxins (PCDDs) and furans (PCDFs) in ambient air were about 54 +- 19 fg TEQ/m3. This value is higher than the predicted concentration of 20-30 fg TEQ/m3 based on the results of the dispersion and deposition model (OPS-model).
