MSC-E Technical Note 2/2002

ABSTRACT

The report considers dioxin/furan (PCDD/F) and polychlorinated biphenyls (PCB) atmospheric emission evaluation for NIS (within the geographical scope of EMEP) for main source categories. Basic years are 1990, 1995 and 1997.

Procedure applied was based on the UNECE EMEP methodology. Wide range of sources of information on production statistics, technological processes features and emission factors were used. When it was impossible to obtain an acceptable quantitative estimate of emission qualitative ranging of sources into 3 categories was done.

Maps of pollutants emission distribution over the 50x50 km² EMEP grid were prepared; for gridding information on the main point sources was collected.

Estimations have showed, that Russia and the Ukraine provide more than 90% of total dioxin/furan emission for domen. Among source categories sharp prevalence of production processes is evident. From this group greatest contribution makes sintering. Decreasing trend of emission is evident in all countries.

For PCBs emission estimation leakage from transformers and damaged capacitors were estimated as the main source of polychlorinated biphenyls (PCB) discharge into the environment. Emission calculation was based on material balance of PCBs production and application in the countries.

Expert estimates of polychlorinated biphenyls emissions in the Russian Federation from electrical equipment with 1°x1° degree spatial resolution based on AMAP PCB inventory [PCB in the Russian Federation…., 2000] were included in the report also.

The obtained estimates of POPs emissions with spatial distribution are intended for the transboundary air pollution modeling; they can be also used by experts of the NIS countries for preparation of national emission estimates.
