Here we show that combustion sources, including waste incinerators, metallurgical processes, power-heating systems and so on, are also important emitters of polybrominated diphenyl ethers (PBDEs) to the atmosphere. Geometric mean PBDE concentrations in the stack flue gases of the combustion sources ranged from 8.07 to 469 ng/Nm3. The sinter plants (24.7 mg/h), electric arc furnaces (EAFs) (11.3 mg/h) and power plants (50.8 mg/h) possessed the largest PBDE emission rates, which were several orders higher than those of the other reported sources. The occurrences of the PBDEs in the flue gases of the power plants and vehicles, as well as their PBDE concentrations statistically highly correlated with combustion-originated PCDD/Fs, revealing that PBDEs should be the products of combustion. The ranking of major PBDE emission sources in Taiwanese PBDE inventory for combustion sources was power plants (30.85 kg/year), vehicles (14.9 kg/year) and metallurgical processes (5.88 kg/year).
在这里，我们表明燃烧源，包括垃圾焚烧炉、冶金过程、供热供电系统等，也是大气中多溴二苯醚（PBDEs）的重要排放源。燃烧源烟道气中 PBDE 的几何平均浓度范围为 8.07 至 469ng/Nm3。烧结厂（24.7mg/h）、电弧炉（EAF）（11.3mg/h）和发电厂（50.8mg/h）拥有最大的 PBDE 排放率，比其他已报道的来源高出几个数量级。这些 PBDE 存在于电厂和车辆的烟道气中，且其 PBDE 浓度与燃烧源产生的 PCDD/Fs 呈高度统计相关，表明 PBDE 应该是燃烧的产物。在台湾的燃烧源 PBDE 清单中，主要 PBDE 排放源的排名为发电厂（30.85 千克/年）、车辆（14.9 千克/年）和冶金过程（5.88 千克/年）。
