Dioxin Emissions in Candidate Countries Improving the knowledgeon dioxin emissions in CCs: A measurements strategyUlrich QuassIUTA e.V., Duisburg, Germany
Dioxin Emissions in Candidate Countries Emission measurements within the project... • WHY (Purpose of measurements) • WHICH (selection of sources) • WHAT (methodology) • WHO (sampling teams, laboratories) • WHEN (time schedule)
Dioxin Emissions in Candidate Countries WHY? Check compliance with limit values Evaluate and improve emission factors P Check potentially relevant sources P First results for unknown source types P Rise awareness P Capacity building in CCs
Dioxin Emissions in Candidate Countries WHICH? Excluded source types: • Waste incinerators • Diffuse non-industrial sources dom. burning, vehicular emissions re-volatilsation of PCDD/F fires
Dioxin Emissions in Candidate Countries WHICH? Probably irrelevant sources, unless specific indications: • Gas/oil power plants • Coal power plants with DeSO2/DeNOx • Blast oxygen furnaces • Primary non-ferrous metal production • Dry cement kilns without supplemental fuels
Dioxin Emissions in Candidate Countries Limit for waste incineration: 0.1 ng I-TEQ/m³ European Pollutants Emission Register (EPER):1 g I-TEQ/year WHICH? Relevance Criteria: A. Stack gas concentration (ng I-TEQ/m³) B. Annual emission (g I-TEQ/year)
Dioxin Emissions in Candidate Countries Limit for waste incineration: 0.1 ng I-TEQ/m³ European Pollutants Emission Register (EPER):1 g I-TEQ/year WHICH? Relevance Criteria (amended): A. Stack gas concentration (ng I-TEQ/m³) B. Annual emission (g I-TEQ/year) C. Stack height (for low flow/ high concentration sources)
Dioxin Emissions in Candidate Countries EN 1948, 1-3 Campaign duration 4-5 days expensive analysis high measurement costs WHAT? Waste incineration Directive: sampling time typ. 6 hours (8 h max) analysis with HRGC/HRMS
Dioxin Emissions in Candidate Countries Cost minimisation by...
Dioxin Emissions in Candidate Countries ...methodological simplification Stack sampling:2-day campaigns, max. three 2(3)-hour samples Analysis: 1st sample extract split into two fractions: • HRGC/HRMS (exact I-TEQ- determination) • simpler GC/MS (order of magnitude) 2nd/3rd sample: • „Simple“ analysis or • analysis only in case of discrepancies
Dioxin Emissions in Candidate Countries WHO? A. Sampling Needed: experienced teams (proof required) 1. preference: companies/institutes from CCs 2. preference: co-operative activities CC/EU 15 3. preference: companies/institutes from EU 15
Dioxin Emissions in Candidate Countries WHO? B. Analysis Favourable: CC based institutes Needs: • experienced laboratories (proof required) • good co-operation with sampling team • QC analysis by independent lab (e.g. TNO, IUTA or other)
Dioxin Emissions in Candidate Countries WHEN? Mar- July 03: proposals of sources (CC institutions) • Not yet measured, operator´s permit available • Likely to be relevant July-Aug 03: priority list/preliminary work plan/call for tenders (TNO/IUTA/DG ENV/JRC)
Dioxin Emissions in Candidate Countries WHEN? Sept 03: decision on work plan/commitments Sept-Nov 03: First phase of measurements Mar – Sept 04: Second phase of measurements Oct 31st, 04:deadline for measurement reports
