“…Many studies investigated PCB concentrations in the settled dust around the world. For example, PCBs values ranged from 11 to 1900 ng g −1 in northern Vietnam [ 87 ], while higher concentrations of total PCBs (199–43,540 ng g −1 ) were detected in dwellings and churches in Illinois, US [ 94 ].…”

“…Nevertheless, it can be used for the short time prediction, and can show the trend of waste flow. The number shows that in the near future, if Viet Nam does not have proper management system, the informal sector can hold a very large flow of materials, and cause much more hazardous impact to environment as denoted by previous research [11,12].…”

“…The rest (11 %) that cannot be reused or recycled is disposed without control at the dismantling site. Considering that the dismantling process in craft villages such as in Te Lo commune is common in Viet Nam, a large number of environmental issues has been founded by the research group of Ehime University [11,12], especially problems regarding hazardous matters including heavy metals and POPs. With the increase of the number of ELV in the future, Viet Nam will have to face against the formation of a series of private dismantling sites if a proper infrastructure for the ELV management system is not prepared.…”

“…Production of iPCBs may occur during a variety of chemical manufacturing processes that involve carbon, chlorine, and high heat. They have been reported in pigments and dyes used in paints, inks, textiles, paper, cosmetics, leather, and in silicone as well as in vinyl chloride and TiO 2 (titanium dioxide) nanoparticles. The most studied process leading to inadvertent PCB (iPCBs) contamination is the production of the diarylide yellow pigment, with the resulting generation of PCB-11. Other iPCBs found abundant in pigments and consumer products include, but are not limited to, PCB-5, PCB-8, PCB-12, PCB-13, PCB-15, PCB-28, PCB-35, PCB-36, PCB-40, PCB-52, PCB-56, PCB-77, PCB-206, PCB-207, PCB-208, and PCB-209, which are also detected in legacy PCB sources in the environment. ,, Recent studies by Washington State’s Department of Ecology have identified a broad distribution of iPCBs in over 200 pigmented consumer products at concentrations up to parts per million . These iPCBs contaminate not only products but also waste streams, air, water, sediment, and biota. , ,, The relative toxicities of common inadvertent iPCBs congeners are not clear. In 2014, EPA nominated 3,3′-dichlorobiphenyl (PCB-11) for evaluation by the National Toxicology Program (NTP) based in part on its ubiquity in the environment .…”
