& open questions

Federal Environment Agency


Annual Dioxin/ Furan emissions


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 PAH emissions


Which PAHs were measured ?

NFR Small combustion Iron and steel (VDI 3467)

Benzo(a)pyrene Benzo(a)pyrene Benzo(a)pyrene

Benzo(k)fluoranthene Benzo(k)fluoranthene Benzo(k)fluoranthene

Indeno(1,2,3-cd)pyrene Indeno(1,2,3-cd)pyrene Indeno(1,2,3-cd)pyrene

Benzo(b)fluoranthene Benzo(b)fluoranthene Benzo(b)fluoranthene

Benzo(j)fluoranthene Benzo(j)fluoranthene

Benzo(ghi)perylene

Anthracene

Benzo(a)anthracene Benzo(a)anthracene

Chrysene(+Trihenylene) Chrysene(+Trihenylene)

Dibenz(a,h)anthracene Dibenz(a,h)anthracene

Benzo(b)naphtol(2,1-d)thiophene


Annual HCB emissions


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)


Immission monitoring data (Hesse)


Seasonal immission trend (Erfurt)


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


Thank you very much for your attention!
