Substance flow analysis of brominated flame retardants and related compounds in waste TV sets in Japan

Investigation of PBDEs in Landfill Leachates from Across Canada

“…The Cape Dorset (CD-2) sample was also collected in a ponded area where the leachate may have been more concentrated. The Whitehorse (WEP) sample was collected from a depth of approximately 25 m. That location is known to contain old leachate (20 years or more), so that high PBDE concentrations are not surprising, given the heavy incorporation of PBDEs as a flame retardant in electronic and other products in the 1980s (Tasaki, et al 2004;ENVIRON 2003). The volume of leachate in the Iqaluit landfill was much greater than at either Hall Beach or Cape Dorset.…”

Level and congener profiles of polybrominated dibenzo-p-dioxins and dibenzofurans in the atmosphere of Beijing, China

“…PBDD/Fs, which are PCDD/F analogs with all chlorine atoms substituted by bromine (WHO, 1994), have received less concern than PCDD/Fs, and data about their environmental level are very scarce. Up to now, PBDD/Fs have been identified and determined in several matrices including: ambient air in Kyoto (Hayakawa et al, 2004), Osaka (Ohta et al, 2002;Watanabe et al, 1995), Shanghai (Li et al, 2008) and at different locations in Taiwan (Wang et al, 2008), at electronic waste dismantling areas in China (Li et al, 2007), in plastics from waste TV sets (Tasaki et al, 2004), as a constituent of flue gases (Wang and Chang-Chien, 2007;Schüler and Jager, 2004), fly ash (Weber and Kuch, 2003;Hagberg et al, 2005;Sovocool et al, 1989;Schwind et al, 1988), sediments (Watanabe et al, 1995;Choi et al, 2003a,b;Hagberg et al, 2005), diet samples (Nomura et al, 2007), shellfish (Fernandes et al, 2008), fish (Ashizuka et al, 2008), adipose tissue (Choi et al, 2003a,b), human milk (Ohta et al, 2002), and blood from people with occupational exposure (Zober et al, 1992). Concerns about PBDD/Fs have increased because brominated flame retardants (BFRs) are extensively used in a variety of materials and are miscible with most plastics.…”

Análisis de la Potencialidad de Ocurrencia de Vertederos Ilegales en la Isla de La Palma, España.

“…A semejanza de otros trabajos (Biotto et al, 2009.;Silvestri y Omri, 2016;Alexakis y Sarris, 2013;Tasaki et al, 2006;Tasaki, 2004;Doak et al, 2017) se ha partido de una serie de variables espacializadas de diferente tipología: variables socioeconómicas como la renta per-capita, población, indicadores económicos, industriales y de la actividad turística; de gestión como tipo de residuo, grado de acceso, accesibilidad, seguridad y control; y por último las características del terreno como la elevación y la pendiente. A partir de este conjunto inicial de variables se obtuvo un subconjunto de variables derivadas mediante la aplicación de diferentes procedimientos de análisis SIG (Demesouka et al, 2014;Kontos et al, 2005;Şener et al, 2010;Şener y Karag, 2011;Uyan, 2014;Akbari y Rajabi, 2017).…”
