| 摘 要： | 对上海市主城区8个家庭和8个办公室的室内降尘于2008年7~8月间用洁净玻璃板进行了定量采集,使用气相色谱-质谱联用仪在负化学电离(NCI)和选择离子扫描(SIM)条件下对室内降尘中BDE-17,-28,-71,-47,-66,-77,-100,-99,-85,-118,-154,-153,-138,-183,-190和BDE-209共16种PBDEs同系物进行了分析,目的是了解上海市室内环境中多溴二苯醚的沉降通量、组成及其影响因素.结果表明,上海家庭和办公室中颗粒态PBDEs的沉降通量分别为(10.9±8.2)和(14.2±11.9)ng.(m2.d)-1,同系物组成以十溴二苯醚(BDE-209)为主,占总量的88.2%~99.2%.办公室环境中颗粒物沉降量较低(3.1±2.0)mg.(m2.d)-1],但颗粒物中PBDEs含量(3 361.6±1 987.4)ng.g-1]明显高于家庭环境(1169.1±647.1)ng.g-1].上海室内降尘中PBDEs的含量与世界其他城市相比处于中等水平.PBDEs室内沉降通量与降尘通量、电器数量及使用时间相关,而与室内装修程度、家具数量的关系不明显.

| Abstract: | Indoor dry deposition of eight homes and offices in the urban area of Shanghai,China were sampled with clean glass plate during July to August of 2008 to study the indoor deposition flux and congener profiles of polybrominated diphenyl ethers(PBDEs).16 PBDEs congeners which including BDE-17,-28,-71,-47,-66,-77,-100,-99,-85,-118,-154,-153,-138,-183,-190 and BDE-209 were measured by GC-MS with negative chemical ionization(NCI) in selected ion monitoring(SIM) mode.The particulate deposition flux of PBDEs in ho... |
