  1. Services to support the update of the EMEP EEA Emission Inventory GuidebookReviewing the POPs Sections of the GuidebookPOPs emissions workshop, May 16 2012Bern, SwitzerlandOle-Kenneth NielsenDepartment of Environmental ScienceAarhus University

  2. Outline • POP aspects of the GB project • Issues identified • Fuel combustion • Fugitive emissions • Industrial processes • Agriculture • Waste

  3. POP aspects of the GB project • Included in task 2 (Review of consistency) • Identification of: • Missing EFs • Inconsistencies • General lack of information on HCB and PCBs • Better coverage for PAHs and PCDD/F

  4. Fuel combustion (1) • Review of 1A1 is not completed • Some comments received during the TFEIP meeting, e.g. the PCDD/F EF for natural gas • General lacking EFs of PCBs and to some degree HCB • “Problem” with many different references across pollutants • An attempt will be made to increase the completeness • The GB chapter 1A2 in general only contains EFs of NOx, SO2 and CO • More comments on cement production later

  5. Fuel combustion (2) • Small combustion • Review underway • Received background paper to the current chapter yesterday – might lead to changes in the conclusions regarding consistency

  6. Fugitive emissions • For catalytic cracking regeneration a PCDD/F EF is proposed to be included • For fluid coking units a PCDD/F EF is proposed to be included • Inclusion of PAH EFs for flaring in refineries

  7. Industrial processes (1) • Metal production (iron and steel & aluminium) • Huge differences between PCDD/F and PAHs EFs for different technologies in iron and steel have to be further investigated • The HCB EF for secondary aluminium production is identified as an outlier and needs further investigation • A number of the EFs for PCBs and PCDD/F attributed to Theloke et al. (2008), however, the study only includes heavy metals • Other metal production • The EFs for PCBs shows significant inconsistences with a factor 1000 difference, this has to be further investigated

  8. Industrial processes (2) • Update of the PCDD/F EF for cement production to follow the latest BREF document • Proposal to update HCB and PCBs EFs for cement production based on reports by SINTEF and VDZ • Some information available in the previous GB has not been implemented in the current GB • If time allows this will be addressed

  9. Agriculture • Implementation of speciated PAH data from the current reference • Currently only total PAH EF is available (Incorrect!) • New information regarding the EF for PCDD/F has been received through the TFEIP and will be evaluated

  10. Waste (1) • Proposal to simplify the EF tables for clinical waste incineration • Proposal to implement US EPA EFs for PAH, also to include HCB and PCBs based on US data • New EFs proposed for municipal waste incineration based on Danish measurements • For cremation it is proposed to update and complete the EFs by using US data • Restructuring of small scale waste burning, this will mean EFs for the different PAHs will be implemented

  11. Waste (2) • Correction of unit error to all EFs for accidental fires in the GB • Correction of units and implementation of speciated PAH EFs for tobacco smoking (3D3)

  12. Future • It should be prioritised to improve the information on POPs in the GB • Identification of missing sources • Improve completeness of the available EFs • Better understanding of uncertainties • Long way to go…
