[Determination of polychlorodibenzo-p-dioxins and furans in ambient air from a rural area in the North East of the Netherlands.]

Abstract

Abstract niet beschikbaarThis report describes the results of immission measurements for PCDD/F in a rural area in the North East of the Netherlands (Drenthe). Results of these measurements show that the average background concentration of polychlorodibenzo-p-dioxins (PCDDs) and furans (PCDFs) in ambient air were about 30 +- 15 fg TEQ/m3. This value is higher than the predicted concentration of 10-20 fg TEQ/m3 based on the results of the dispersion and deposition model (OPS-model). In addition, also tetra-and-pent- congenerprofiles and congener patterns are studied and compared with emissions patterns.HIMH HIGB VV
