| Abstract | Atmospheric and aquatic emission load of hexabromocyclododecane (HBCD) for the period 1986-2030 were estimated by substance flow analysis. Through the investigation of quantitative HBCD life cycle, estimated HBCD stock in the use phase shows a continuous increase, indicating that emissions from the materials containing HBCD will be potentially long-term sources of pollutants leaching or volatizing to the environment. In Japan, 571 kg/year and 41 kg/year of HBCD was calculated to emit to the atmospheric and aquatic environment in 2000, respectively. This corresponds to 0.03 % of the consumed HBCD quantity in Japan. These environmental emissions of HBCD were increasing rapidly until 2011. On the other hand, decreasing trend for HBCD were estimated between 2012 and 2030 and the emissions were simulated to be as high as 225 kg/year in 2030. This is due to the scenario that the use of HBCD for textiles would be stopped. The largest component of the emissions is simulated to be into the atmosphere from the consumer product because the stock in the use phase has been growing over the whole period. The source profile of environmental emission would shift from upstream to downstream of product chain. The present study gives an insight to obtain basic information for long term measures toward strategic chemical management considering their life cycle. |
