Continuous sampling of emission into air of dioxins has been one of the targets of Directive 2010/75/EU Of The European Parliament And Of The Council on industrial emissions (Integrated Pollution Prevention and Control, IED Directive) since year 2010. The present research was aimed at verifying the applicability of a long-term sampling system at the sinter plant of a large steel works in Taranto, Southern Italy, and to perform its validation compared to the standard reference method.Automated long-term samplings of 15 and 30 d were performed in parallel with manual short-term sampling, the latter with a frequency of two per week. Concentrations range was 0.05–0.20 ng I-TEQ/N m3 thus ensuring good coverage around the level of interest of 0.1 ng I-TEQ/N m3, as a typical Emission Limit Value for combustion plants. In addition the long-term device was used for short-time sampling in parallel with manual sampling showing an external variability between ± 0.05 ng I-TEQ/N m3 thus proving to be acceptable.As a result of the successful validation trial the long term emission sampling was enforced as Emission Limit Value official control technique.
