Epileptic power supply in Sub-Saharan countries of Africa has warranted the use of power generators as an alternative source of power supply. Exhaust emission from these generators is associated with Polycyclic Aromatic Hydrocarbon (PAHs). Hence, this study focused on the determination of levels of PAHs in the emission of different brands of power generators used in Nigeria. Exhaust emissions of different power generators were sampled using a filter-sorbent sampling system with polyurethane foam (PUF) as an adsorbent material. Analysis of PAHs was carried out using a Gas Chromatograph coupled to a mass selective detector (GC- MS) operated on Electron Ionization (EI) mode. The results showed the ∑ PAHs range 14.91-26.0 Bap was the most abundant of all the compounds with a concentration of 2.6 with a range of 2.08-3.07 . The Incremental Life Cancer Risk (ILCR) values of all the generator's emission sampled are higher than 10 for both children and adult which indicate a high potential cancer risk from inhalation of emission from these generators while Hazard Quotient (HQ) values from all the power generating set in this study are all above 1 which indicated high associated non-carcinogenic. The study revealed the levels of PAHs associated with the emission of power generators in Nigeria.
非洲撒哈拉以南国家的癫痫供电情况使得使用发电机作为替代电源成为必要。这些发电机的废气排放与多环芳烃（PAHs）有关。因此，本研究聚焦于测定尼日利亚使用的不同品牌发电机排放物中的多环芳烃水平。使用以聚氨酯泡沫（PUF）作为吸附材料的滤器 - 吸附剂采样系统对不同发电机的废气排放进行采样。使用与在电子电离（EI）模式下运行的质量选择检测器联用的气相色谱仪（GC - MS）对多环芳烃进行分析。结果表明，∑多环芳烃范围为14.91 - 26.0，苯并[a]芘是所有化合物中含量最高的，浓度为2.6，范围为2.08 - 3.07。所有采样发电机排放物的增量生命癌症风险（ILCR）值对于儿童和成人都高于10，这表明吸入这些发电机排放物存在很高的潜在癌症风险，而本研究中所有发电机组的危害商（HQ）值均高于1，表明存在高度相关的非致癌性。该研究揭示了尼日利亚发电机排放物中多环芳烃的水平。
