reproductive and dermal toxicities. Therefore in 1997 the Word Health Organisation (WHO) extended the concept of toxic equivalency (TEQs) 3 also to these group of “dioxinlike” PCBs.
At the moment a fraction of the produced PCBs is collected with the household waste and burned in incinerators. PCBs are evaporated during waste incineration and are partially destroyed during the incineration process, dependent on residence time/temperature. Catalytic dioxin destruction shall additionally reduce the emissions of PCBs. Anyway all PCBs left in the flue gas are emitted in the environment. Some publications present this as an additional source of PCBs 2,4,5,6. This work aims to investigate the congeners and homologous group distribution of PCBs in emission samples of municipal solid waste incinerators and to calculate the WHO-TEQPCB in relation to the WHO-TEQPCDD/F.
