Although there have been growing concerns on the influence of polybrominated dibenzo-p-dioxins and furans, PBDD/DFs, related substances of polychlorinated dibenzo-p-dioxins and furans (PCDD/DFs) on the environment and human health, little is known about the emission pathways of these compounds. The Law Concerning Special Measures against Dioxins of Japan requires the government to promote "the research and study of PBDD/DFs with regard to the extent of their effects on human health, the process of generation, and others". It also states the necessity of the governmental measures based on the survey results. Since 2002, the Ministry of the Environment of Japan (MOEJ) has conducted a series of field studies to survey the emissions of PBDD/DFs and related compounds from several industrial processes involving brominated flame retardant (BFRs). It is important for the global community to share the knowledge on PBDD/DFs sources and their estimated emission, in order to consider the way to reduce the total emission of PBDD/DFs. Here we report the survey results on the current status of PBDD/DFs emissions in Japan.
