冶炼等冶金工艺可产生有机杂质，如有机氯化物化学品、多氯二苯并对二恶英和多氯二苯并呋喃。摘要本研究旨在探讨台湾地区134位作业工人血清中PCDD/F浓度与电弧炉、二次炼铜厂与二次炼铝厂周围空气中PCDD/F浓度之关系。结果表明，人工流产工人血清PCDD/F水平最高（21. 9 pgWHO-TEQ/g lipid），铜冶炼厂工人次之（21. 5 pgWHO-TEQ/g lipid），电炉厂工人最低（18. 8 pgWHO-TEQ/g lipid）。这仍然高于生活在城市垃圾焚烧厂5公里范围内的居民的水平（14. 0 pgWHO-TEQ/g脂质）。环境样品中，铜冶炼厂环境空气中PCDD/F含量最高（12.4pgWHO-TEQ/Nm 3），铝冶炼厂较低（7. 2 pgWHO-TEQ/Nm 3），电弧炉行业最低（1. 8 pgWHO-TEQ/Nm 3）。在铜冶炼厂采集的血清和空气样本中，同源物的分布情况是一致的，但在酸性硫酸盐和电弧炉中则不然。在二次铜冶炼厂，空气中的PCDD/Fs水平可能直接与工人体内积累的PCDD/Fs有关，因为PCDD/Fs排放的同系物模式非常稳定。
Metallurgical processes, such as smelting, can generate organic impurities such as organic chloride chemicals, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs). The objective of this study was to elucidate the serum PCDD/F levels of 134 workers and ambient air levels around electric arc furnaces (EAF), secondary copper smelters and secondary aluminum smelters (ALSs) in Taiwan. The highest serum PCDD/F levels were found in the ALSs workers (21.9pgWHO-TEQ/g lipid), with lower levels in copper smelter workers (21.5pgWHO-TEQ/g lipid), and the lowest in the EAF plant workers (18.8pgWHO-TEQ/g lipid). This was still higher than the levels for residents living within 5km of municipal waste incinerators (14.0pgWHO-TEQ/g lipid). For ambient samples, the highest ambient air PCDD/F level was in the copper smelters (12.4pgWHO-TEQ/Nm3), with lower levels in ALSs (7.2pgWHO-TEQ/Nm3), and the lowest in the EAF industry (1.8pgWHO-TEQ/Nm3). The congener profiles were consistent in serum and in air samples collected in the copper smelters, but not for ALSs and EAF. In secondary copper smelters, the air PCDD/Fs levels might be directly linked to the PCDD/Fs accumulated in the workers due to the exceedingly stable congener pattern of the PCDD/F emission.
