2010年冬季在黑龙江省4个城市采集了14份室内粉尘样本。对14种多溴联苯醚（PBDEs）进行了鉴定和定量。14种多溴二苯醚的浓度范围为240 ~ 9270 ng/g，中位数为2520 ng/g。BDE209为优势同系物，浓度范围为234 ~ 9190 ng/g，占总浓度的97.2%。BDE17、28、66、47组与BDE85、99、100组、BDE153与BDE154、BDE209与BDE183之间呈显著正相关（r >.8,p< 0.005），说明室内环境中BDE17、28、66、47组与BDE85、99、100组存在相似的来源和途径。主成分分析表明，多溴二苯醚的主要来源是商用五溴二苯醚和十溴二苯醚。人体暴露分析表明，1-5岁儿童对多溴二苯醚的暴露量最高。
Fourteen indoor dust samples were collected in 2010 winter from four cities in Heilongjiang Province, China. Fourteen polybrominated diphenyl ethers (PBDEs) were identified and quantified. Concentration of the total 14 PBDEs ranged from 240 to 9,270 ng/g, with the median of 2,520 ng/g. BDE209 was the dominant congener with concentrations ranged from 234 to 9,190 ng/g, accounting for 97.2 % of the total concentration. Positive correlations (r > 0.8,p< 0.005) were found between the group of BDE17, 28, 66, 47 and the group of BDE85, 99, 100, between BDE153 and BDE154, between BDE209 and BDE183, indicating the similar sources and/or pathways in indoor environment. Principal component analysis showed that the major sources of PBDEs were commercial Penta-BDEs and Deca-BDEs. Human exposure analysis showed that children of 1–5 years old had the highest exposure to PBDEs.
