Investigation of Pcns and Sccps in Ambient Air and Stack Emission(2/3)

Project Details


Polychlorinated naphthalenes (PCNs) and short-chained chlorinated paraffins (SCCPs) have received much public concern due to their adverse effects on human health and the characteristics of POPs including bioaccumulation, persistence, and long-range transport. Data on concentrations and characteristics of these compounds in Taiwan are very limited and none research has been conducted to systematically evaluate the distribution of these compounds in environment and to investigate the emission strength from major sources. In this study, the concentrations and distribution of congeners of PCNs and SCCPs in ambient air of urban, rural and industrial areas in northern Taiwan will be investigated via sampling and analysis. Moreover, the partitioning of PCNs or SCCPs congeners between gaseous and particulate phases at two municipal waste incinerators (MWI) equipped with different air pollution control devices (APCDs) and an electric arc furnace (EAFs) in Taiwan will be evaluated via stack sampling and analysis. The stack gas will be sampled and analyzed at two existing MWIs to evaluate the removal efficiencies of these compounds achieved with the air pollution control devices (APCDs) adopted. The emission factors and the distribution of congeners in stack gas will be compared to those in ambient air to pinpoint the potential sources. Dominant congeners of these compounds in gaseous and solid phases of ambient and stack gas samples will also be determined. The results obtained from this research can provide good baseline data of PCNs and SCCPs in ambient air and emission characteristics from typical sources and relevant information can assist government to enact the policy for regulating PCNs and SCCPs.
