ated The results should allow to propose methods for the minimizing of the emissions of the pollutants Besides con- struction
and out-testing of suitable sampling system, the development of reproducible analyzing technique, allowing the detection of single nitro-PAH components at 
trace concen- tration level, had been an important pre-condition for routine monitoring 2. Working steps The project was divided into 
the following phases - Installation of suitable sampling system for nitro-PAH' at the furnace test facility of the institute, - 
testing of selective procedures for the enrichment of nitro-PAH' from the complex substance mixtures occurring in the combustion process, - optimization of sensitive trace analytical detection methods, - monitoring of the nitro-PAH emissions in dependence of combusrion-and fuel-parameters, - evaluation of the results with respect to possible measures for the reduction of emissions 3. Results Within the scope of the described research projectthe nitro-PAH emissions have been studied at four different domestic furnaces For that, the furnace test facility of the institute had to be extended by special sampling system for particlebound nitro-PAH' The samples obtained from the flue gas -filtration residue, aqueous condensate, rinsing liquid - were extracted and cleaned up by adsorption chromatography and semi-preparative HPLC Subsequent analysis of nitroPAH' in the picogram-range was carried out routinely by capillary gas chromato raphy with nitrogen-specific detection and additionally by means of reverse phase HPLC wit: post- chromatographic derivatization and fluorescence detection The shift-fire cast boiler, fueled with coke nuts of hard coal, emitted, besides larger amounts of 9--anthracene, --pyrene and 6--benz()pyrene also traces of --and 2--naphthaleneaswell as 2--fluoreneand 3- -fluoranthene Related to the fuel-feeding the mean total emission of all detected nitro PAH 1 compounds was 4 8 pc~ /kg Qual| Model Type | Helical gear boxes H2 |
