Annual Dioxin/ Furan emissions

3 The German POPs inventory - Kristina Juhrich - Bern - May 16th 2012
Completeness
• Dioxin/ Furan emission inventory is nearly complete
• Measurement data are available for several years
• Data quality is satisfactory
But:• large uncertainties regarding the (illegal) waste wood consumption
in small combustion plants
• Breaks in time series due to incomplete measurement data
• Possible gap: 6.C.e Small scale waste burning

Annual HCB emissions
![Page 7: The German POPs inventory A short description Improvements Challenges & open questions](https://reader035.vdocuments.us/reader035/viewer/2022070406/5681406a550346895dabe57a/html5/thumbnails/7.jpg)
7 The German POPs inventory - Kristina Juhrich - Bern - May 16th 2012
Improvements and open questions
New: • HCB measurements from waste incineration plants and copper
production
Still missing:• Pesticide use: 1.4- 5.6 kg But no activity data from 1990 available
• Smoke munitions: 380 kg in 2010 / 1,500 kg in 2003 ?! But the values seem to be remarkable high and no activity data from 1990 are available
• Chemical industry ?• Steel industry ?• Cement production ?

Annual PCB emissions

challenges
Different PCB measurements: • Ballschmiter value (PCB 28, 52, 101, 138, 153, 180 )* 5 • WHO 2005 (77, 81, 126, 169, 105, 114, 118, 123, 156, 157, 167,
189) TEQ
Need to be checked:• PCB emissions from lead and zinc production (values and trend)
Still missing:• PCB emissions from electrical equipment (capacitors and
transformers)

Further steps
• Inform the experts about the importance of the POPs inventory
• Review the inventory to check the existing emission factors and to identify missing source categories
• Evaluation of monitoring data to get information of the expected trend, possible gaps and key sources
• Contact the industry for data
• Measurement projects depending on financial resources
• Information exchange with the informal network of POPs inventory compilers, which is established by Rob Whiting
