Specific yields were determined for tars, benzo(a)pyrene, diberzo(ah)anthracene and benzo(ghi)perylene from the main PAH sources in aluminium production using Soderberg cells with anode pastes based on medium- (MP) and high- (HP) softening-point pitches. It was evaluated that the most significant source of carcinogens from the Soderberg cell is the open hole during the process stage of repositioning the current-carrying studs. This phase of the work contributes about 60-70% of the total carcinogenic PAH emissions to the atmosphere. It is shown that a replacement of MP with HP results in a decrease of the specific tar yields from all sources, but it does not reduce the specific yield of the carcinogenic PAHs and therefore the carcinogenic danger of this technology.
