| Abstract | In Japan, organophosphate and polybrominated flame retardants areused in building materials and electric appliances to protect them from firehazards. In this study, to identify the emission sources of these flame retardantsto indoor air, the migration rates (flux) of organophosphate and polybrominatedflame retardants from building materials and electrical appliances to solidextraction disks that were placed in contact with the interior surfaces weremeasured. In addition to the migration test, indoor air and outdoor air con-centrations of these flame retardants were investigated. With regard to buildingmaterials in a newly built house, triethylphosphate (TEP) and tributylphosphate(TBP) were detected in the wall and ceiling coverings, and tris(2-butoxyeth-yl)phosphate (TBEP) was detected in the wooden flooring cleaned with a floorpolish agent. With regard to electrical appliances, triphenylphosphate (TPHP)was predominantly detected in computer monitors and tris(2-chloroethyl)phosphate (TCEP) in television (TV) sets, with the highest median levels. Amongthe polybrominated compounds, only 2,2¢,4,4¢-tetrabromodiphenyl ether (BDE-47) was detected from a few old TV sets manufactured before 1995. In an indoorand outdoor air survey, nine organophosphates and nine polybrominated flameretardants were detected from indoor air. In outdoor air, only four organo-phosphate flame retardants were detected. The maximum level of indoor or-ganophosphate compounds was 1260 ng/m3with tris(2-chloro-1-methylethyl)phosphate (TCPP), and that of polybrominated compounds was 29.5 ng/m3withhexabromocyclododecane (HBCD). Tetrabromobisphenol A (TBBPA) was notdetected in this study, although it has the largest demand among flame retard-ants in Japan. The results of the migration test and the indoor air survey revealedthat in indoor air, organophosphate compounds were more predominant thanpolybrominated compounds in Tokyo. |
