A preliminary report on the investigation of the comparative toxicity of combustion products of high impact polystyrene with and without decabromodiphenyloxide/antimony trioxide as a flame retardant using 2,3,7,8-tetrabromodibenzo-p-dioxin and 2,3,7,8-tetrabromodibenzofuran as positive controls

Abstract This program was designed to address the issue of the formation and toxicity of brominated dioxins and/or furans when formed as part of the soot and char in real fire environments. Results are reported from analytical and comparative animal toxicity studies conducted on soot and char samples generated by combustion conditions designed to simulate real fires for high impact polystyrene with and without decabromodiphenyloxide/antimony trioxide as the flame retardant. Additionally, results are reported for the same types of toxicity studies conducted on pure samples of 2,3,7,8-tetrabromodibenzo-p-dioxin and 2,3,7,8-tetrabromodibenzofuran.
