Abstract

Indoor air (gas and particle phase) and dust samples were collected from 10 houses, 44 apartments, 10 day care centers, 10 offices, 17 new cars and two car dealership halls from Stockholm, Sweden, and analyzed for polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD). Median ΣPBDE concentrations in air were 330, 58, 4000, 14000 and 510 pg/m(3) in houses, apartments, day care centers, offices and cars, respectively. Median ΣPBDE concentrations in dust were 510, 1400, 1200, 1200 and 1400 ng/g in houses, apartments, day care centers, offices and cars, respectively. HBCD was detected in most dust samples (median range, 45-340 ng/g) but only in a few air samples (median range, <1.6-2.0 pg/m(3)). For all microenvironments, the brominated flame retardant (BFR) found in highest concentration in air was ΣDecaBDE, primarily BDE-209, followed by ΣPentaBDE, and in dust, ΣDecaBDE, followed by HBCD (offices, day care centers, cars) or ΣPentaBDE (houses, apartments). Positive correlations were found between matched air and dust samples for ΣPentaBDE, but not for ΣDecaBDE.

摘要

室内空气(气体和颗粒相)和灰尘样本取自瑞典斯德哥尔摩的 10 所房屋、44 间公寓、10 家日托中心、10 间办公室、17 辆新车和两个汽车经销厅,用于分析多溴二苯醚(PBDEs)和六溴环十二烷(HBCD)。空气中ΣPBDE 的浓度中位数分别为 330、58、4000、14000 和 510 pg/m3 在房屋、公寓、日托中心、办公室和汽车中。灰尘中ΣPBDE 的浓度中位数分别为 510、1400、1200、1200 和 1400 ng/g 在房屋、公寓、日托中心、办公室和汽车中。HBCD 存在于大多数灰尘样本中(中位数范围为 45-340 ng/g),但仅存在于少数空气样本中(中位数范围为 <1.6-2.0 pg/m3)。对于所有微环境,空气中浓度最高的溴化阻燃剂(BFR)是ΣDecaBDE,主要是 BDE-209,其次是ΣPentaBDE,而在灰尘中,ΣDecaBDE 紧随其后是 HBCD(办公室、日托中心、汽车)或ΣPentaBDE(房屋、公寓)。在匹配的空气和灰尘样本中发现了ΣPentaBDE 之间的正相关关系,但不是ΣDecaBDE。
