Abstract niet beschikbaar
This report describes the first results of the method development for the measurement of polychlorodibenzene-p-dioxins (PCDDs) and -furans (PCDFs) in the ambient air in the Netherlands with the aim to a better understand of occurrence and dispersion in relation to sources of these compounds. Results will be used for verification/validation of dispersion calculations by use of the dispersion and deposition model (OPS-model). The sampling strategy as well as the development of the analytical procedures for measuring PCDD/F in air will be discussed. Preliminary results indicate that with the present technique extreme low concentrations of PCDD/F can be measured with a reproducability of 20% in ambient air of 5 fg.TEQ.m-3 or higher. In an industrial/urban location in the Netherlands, background concentrations of 15 fg. TEQ.m-3 and immission concentrations of exceeding 80 fg.TEQ.m-3 have been measured.
