Abstract
Polychlorinated dibenzothiophenes (PCDBTs), polychlorinated thianthrenes (PCTAs) and polychlorinated diphenylsulphides (PCDPSs) which are sulphur analogues for polychlorinated dibenzofurans (PCDFs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated diphenyl ethers (PCDEs), were analyzed by HRGC/HRMS in different samples from a metal reclamation plant. The samples were gas phase samples from an aluminium smelter and a car shredder and ash and slag from processes where different temperatures (300–850 °C) were used. Tri-, tetra-and pentaCDBTs were most abundant sulphur chloroaromatics at amounts comparable to PCDDs and PCDFs in emissions and wastes. Small amounts of tri- and tetraCTAs were identified in car shredder samples. Occurence of PCDPSs remained uncertain due to interferences even in GC/HRMS analyses.
