The Japanese Government introduced the Law on Recycling of End-of-Life Vehicles (ELV Recycling Law) in 2002. This law requires
manufacturers to retrieve chlorofluorocarbons (CFCs), airbags, and automobile shredder residue (ASR) from ELVs and to properly
recycle the remaining materials. This framework is compared with European ELV directives. Pilot-scale incineration plant testing
has revealed a greater formation of by-product persistent organic pollutants (POPs) during the primary combustion of ASR compared
to normal municipal solid waste. This may be attributed to the abundance of chlorine, Cu, and Fe in ASR, as Cu and Fe have
been found to catalyze the formation of POPs under certain conditions. However, most by-product POPs were destroyed by the
secondary combustion, and almost all were removed after flue gas treatment. The direct melting system is a shaft-type gasification
and melting technology that has proved effective in many municipal solid waste applications. This system can be applied to
ASR recycling for effective decomposition of brominated flame retardants and polybrominated dioxins. 相似文献

In this study, the development of a toxicity evaluation method for dioxins in human milk by enzyme-linked immunosorbent assay (ELISA) was reported. A total of 17 human milk samples were tested by ELISA and by gas chromatography/mass spectrometry (GC/MS) to assess whether the ELISA performed on samples obtained from primiparas could be considered as reliable enough for identifying a dioxins contamination in human milk. The concept of toxicity equivalent quantity (TEQ) screening was validated by comparing TEQ values for a set of human milk samples to the ELISA responses predicted for those samples. A fairly good correlation (r=0.920) between immunoassay and GC/MS was achieved for human milk. This ELISA should be useful for biological samples monitoring. 相似文献
