Intensive 'motorization' accompanied by urbanization is a notable social change in developing and newly industrialized countries that generates a large burden of end-of-life vehicles (ELVs). ELVs are not only important materials for reuse and recovery but also contain hazardous chemicals such as heavy metals, polychlorinated biphenyls (PCBs) and brominated flame retardants. Primitive waste treatment including open burning results in environmental release of complex mixtures of dioxin-related compounds (DRCs) and polycyclic aromatic hydrocarbons (PAHs). In our previous study, we determined the concentrations of PCBs, polybrominated diphenyl ethers (PBDEs) and DRCs in dust samples from an ELV recycling site, Thuyen village, in northern Vietnam to evaluate their environmental release and human exposure (Takahashi et al. 2016). The results indicated significant emission of PCBs and DRCs in ELV recycling activities. In this study, we assessed the occurrence of 942 organic micropollutants in dust samples collected from ELV recycling workshops in Thuyen village in northern Vietnam and urban area of Hanoi city by using an Automated Identification and Quantitation System with a Database (AIQS-DB) for GC-MS.
