Decomposition of two types of electric wires considering the effect of the metal in the production of pollutants
چکیده انگلیسی

Combustion runs at 700 °C in a horizontal laboratory furnace were carried out on two different electric wires (PVC and halogen-free wire). Tests were performed in the presence and in the absence of the metal conductor of the wires. The analyses of the polycyclic aromatic hydrocarbons (PAHs), chlorobenzenes (CBzs), chlorophenols (CPhs), mono- to octa-chlorodibenzo-p-dioxin and dibenzofurans (PCDD/Fs), and dioxin-like PCBs are shown. Regarding semivolatile compounds, PAHs production decreases in the presence of metal, while a higher amount of chlorinated compounds are emitted. Respect to the PCDD/Fs, the PVC wire in the presence of metal presents the highest emission, with a much more emission of furans than dioxins. The maximum emission is with 2 or 3 chlorine atom PCDD/Fs. PCBs emission correlates with PCDD/F production and represents 3–4% of total toxicity, determined by using WHO2005 factors.


► Haloge-free and PVC wires are studied at different decomposition conditions.
► Runs are performed in the presence and in the absence of the metal conductor.
► Analysis of the pollutants emitted is done.
► Important differences were found at the different experimental conditions.
► Metal enhances chlorinated compounds emission while decreases aromatics.
