Contamination and Emission Inventory of PCDD/PCDF: Insights from the 2nd Dioxin Workshop

The 2nd Dioxin Workshop in Bratislava (February 2-3, 2004) explored the lifecycle of PCDD/PCDF, emphasizing their water insolubility and tendency to adsorb to solids. Experts presented methodologies for gathering contamination data, including bibliographical searches and inquiries with national environmental organizations. Significant barriers were identified in data accessibility, both public and administrative. The workshop concluded with a focus on estimating emissions using activity rates and coefficients, highlighting collaboration with various international and national databases for more effective inventory practices.

Presentation Transcript

  1. PCDD/PCDF are virtually insoluble in water • PCDD/PCDF are then adsorbed to the solids present in water • Life cycle of PCDD/ PCDF: 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  2. The main ways for contamination (UNEP Toolkit 2003) 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  3. The inventory methodology:  Gathering of measured data --> Bibliographical search on international data banks --> Inquiry at national organizations (environmental protection agency, ministry of environment …) --> Query at IOW partners in some CC for the relevant information sources 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  4. Results:  No public data available or  If any data, not easily accessible for example, even with local partners, administrative barriers exist 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  5.  Gathering of estimated data using this equation Activity rate X Emission coefficient  Sources for activity rates: Eurostat and CEPMEIP (Co-ordinated European Programme on Particulate Matter Emission Inventories, Projections)  Sources for default coefficients: UNEP Toolkit, Dioxins inventory in Europe (DG ENV), national inventories (Ireland, New Zealand …) 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  6. Results: used default coefficient emission (to be completed) 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  7. Example of data gathered for two industrial branches 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  8. 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  9. ROMANIA 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  10. POLAND 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  11. CZECH REPUBLIC 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  12. SLOVAK REPUBLIC 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004

  13. Further work: 1 - Finalization of estimated emission gathering in water and land 2 - Validation of these results by national experts 2nd Dioxin workshop, Bratislava, February 2 - 3, 2004
