California’s updated furniture flammability standard, TB117-2013, can be met without the use of chemical flame retardants (FRs). FRs have been associated with neurological damage, reproductive toxicity, thyroid disease, and cancer. We collected dust from classrooms and other nonresidential spaces on four U.S. college campuses that met one of California’s two older FR-reliant standards (TB117, TB133) or the newer TB117-2013. We hypothesized that spaces with TB117-2013-compliant furniture would have lower levels of FRs in dust. We detected all 43 targeted FRs, and FRs were detected in each of the 86 samples. We prioritized 14 FRs for statistical analysis based on their prevalence in dust and use in furniture and textiles. Concentrations of three polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCDD), and tris(2-chloroethyl) phosphate (TCEP) were significantly lower in TB117-2013 spaces compared to spaces adhering to FR-reliant standards. Concentrations of BDE 209, decabromodiphenylethane (DBDPE), bis(2-ethylhexyl)-3,4,5,6-tetrabromophthalate (BEH-TEBP), hexabromobenzene (HBB), and tetrabromobisphenol A (TBBPA) were significantly lower in spaces meeting TB117-2013 compared to TB133 spaces. We report the highest dust levels of BDE 209, 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB), DBDPE, and TCEP in the U.S. Spaces adhering to the revised standard, TB117-2013, had lower dust concentrations of harmful FRs, suggesting less FR was used in the furnishings.

满足新家具易燃性标准TB117-2013的大学空间中阻燃剂浓度较低

无需使用化学阻燃剂(FR)即可满足加利福尼亚更新的家具易燃性标准TB117-2013。FR与神经系统损伤,生殖毒性,甲状腺疾病和癌症有关。我们从四个美国大学校园的教室和其他非居住区收集了灰尘,这些校园达到了加利福尼亚州两个较旧的FR相关标准之一(TB117,TB133)或较新的TB117-2013中的一个。我们假设配备TB117-2013家具的空间灰尘中的阻燃剂含量较低。我们检测了所有43个靶向FR,并且在86个样品中的每一个中均检测到FR。我们根据其在粉尘中的流行程度以及在家具和纺织品中的使用情况对14个FR进行了优先级统计分析。三种多溴二苯醚(PBDEs),六溴环十二烷(HBCDD),与遵守FR相关标准的空间相比,TB117-2013空间中的磷酸三(2-氯乙基)酯(TCEP)和磷酸三(2-氯乙基)酯(TCEP)明显更低。在满足TB117的空间中,BDE 209,十溴二苯乙烷(DBDPE),双(2-乙基己基)-3,4,5,6-四溴邻苯二甲酸酯(BEH-TEBP),六溴苯(HBB)和四溴双酚A(TBBPA)的浓度明显降低。 -2013年相比,TB133空间。我们报告,在遵循修订标准TB117-2013的美国太空中,BDE 209、2-乙基己基-2,3,4,5-四溴苯甲酸酯(EH-TBB),DBDPE和TCEP的最高粉尘水平较低有害FR浓度过高,表明家具中使用的FR较少。在满足TB117-2013要求的空间中,与TB133空间相比,满足TB117-2013要求的空间中的6-四溴邻苯二甲酸酯(BEH-TEBP),六溴苯(HBB)和四溴双酚A(TBBPA)明显更低。我们报告,在遵循修订标准TB117-2013的美国太空中,BDE 209、2-乙基己基-2,3,4,5-四溴苯甲酸酯(EH-TBB),DBDPE和TCEP的最高粉尘水平较低有害FR浓度过高,表明家具中使用的FR较少。在满足TB117-2013要求的空间中,与TB133空间相比,满足TB117-2013要求的空间中的6-四溴邻苯二甲酸酯(BEH-TEBP),六溴苯(HBB)和四溴双酚A(TBBPA)明显更低。我们报告,在遵循修订标准TB117-2013的美国太空中,BDE 209、2-乙基己基-2,3,4,5-四溴苯甲酸酯(EH-TBB),DBDPE和TCEP的最高粉尘水平较低有害FR浓度过高,表明家具中使用的FR较少。
