Abstract：
We measured PAHs concentrations to understand the potential short and long-term health risks to workers. In the anode cooking area, the lowest and highest concentrations of PAHs were found for DahA (dibenzo[a,h]anthracene) at 0.373 ± 0.326 µg/m3 and Chry (chrysene) at 1.923 ± 1.258 µg/m3, respectively. In the anode-making area, these concentrations were higher, with DahA at 0.435 ± 0.221 µg/m3 and Chry peaking at 3.841 ± 1.702 µg/m3. Risk assessment based on these concentrations indicates a hierarchical order of individual PAHs risks in the anode cooking area, led by BaP (benzo[a]pyrene), followed by other specific PAHs compounds. The total hazard quotient (THQ) for PAH exposure in both anode-making and cooking areas significantly exceeds the threshold for considered cancer risk, emphasizing the considerable danger to workers. This study underscores the urgent need to mitigate exposure to PAHs in industrial settings to protect worker health from the carcinogenic risks of such hazardous compounds.
摘要：
我们测量了PAHs浓度，以了解工人潜在的短期和长期健康风险。在阳极烹饪区，在DahA中发现了最低和最高的PAHs浓度(二苯并[a，h]蒽）分别为0.373±0.326µg/m3，Chry（chrysene）分别为1.923±1.258µg/m3。在阳极制造区，这些浓度更高，DahA为0.435±0.221µg/m3，Chry的峰值为3.841±1.702µg/m3。基于这些浓度的风险评估表明阳极烹饪区域中单个PAHs风险的分层顺序，由BaP（苯并[a]芘）领导，其次是其他特定的PAHs化合物。在阳极制造和烹饪区域中，PAH暴露的总风险商（THQ）大大超过了考虑癌症风险的阈值。强调对工人的巨大危险。这项研究强调了迫切需要减少工业环境中PAHs的暴露，以保护工人健康免受此类有害化合物的致癌风险。
