文摘

Fine organic particulate matter emitted from an industrial-scale boiler burning no. 2 distillate fuel oil has beencharacterized on a molecular basis using GC/MS techniques.Most of the identified compound mass consists ofn-alkanoicacids (42.0-51.5%), aromatic acids (5.8-22.6%), andn-alkanes (6.7-25.0%). Polycyclic aromatichydrocarbons(PAH) and oxygenated PAH (oxy-PAH) together comprise3.1-8.6% of the identifiable mass and together withchlorinatedcompounds (5.8-16.4%) show the largest variations inemission rates between the two experiments reported here.An increase in chlorinated compound emissions betweentests is accompanied by a similar increase in elementalcarbon (i.e., soot) and PAH emissions, which may followtheresults of laboratory experiments that suggest that thepresence of chlorinated compounds can enhance both sootand PAH formation. Differences between the hopanesdistribution in the boiler exhaust versus that found inbothvehicle exhaust and in the southern California atmospheresuggest that the oil-fired boiler exhaust is at most aminorcontributor to the atmospheric aerosol, which isconsistentwith inferences drawn from local emissioninventories.
