The effects of temperature and the amount of copper chloride on the types and yields of the toxic emissions from combustion of polyvinyl chloride were investigated. The results suggest that a large amount of polycyclic aromatic hydrocarbons (PAHs) are released from combustion of pure polyvinyl chloride, accompanied by a small amount of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs). Copper chloride can effectively enhance the formation of PCDD/Fs while possibly inhibit formation of PAHs. metal chlorides are possibly one of the main factors to enhance the PCDD/Fs formation from combustion of polyvinyl chloride.
