Concentration, composition and sources of polycyclic aromatic hydrocarbons (PAHs) in kitchen depositions from different sampling categories such as restaurants, university mess and houses were investigated, and associated human exposure risk through dietary intake, inhalation and dermal contact was determined. The PAHs in the samples were extracted by supramolecular solvent based microextraction (SUPRAS) method and the concentrations were determined by high pressure liquid chromatography (HPLC) with fluorescence detection. The mean of Σ16PAHs concentration was found to be the highest (386.09 ± 413.17 mg kg) for restaurants followed by mess (80.91 ± 92.81 mg kg) and houses (24.65 ± 10.52 mg kg). Traffic sources were found to be predominant contributors of PAHs in restaurants while cooking activities were the sources for mess and houses. Three- and five-ring PAHs were prominent in restaurants and mess samples while two- and three-ring PAHs contributed the most in houses samples. Non-cancer risk (hazard index) from exposure to these PAHs was found to be within safe limits i.e. 2.70E-09 to 7.46E-08. Estimated lifetime cancer risk was found to range from 2.46E-06 to 7.81E-04 from exposure to these PAHs and indicates significant risk due to exceeding the guideline value of 10.
研究了不同采样类别（如餐厅、大学食堂和住宅）的厨房沉积中多环芳烃（PAHs）的浓度、组成和来源，并通过饮食摄入、吸入和皮肤接触确定了相关的人体暴露风险。样品中的 PAHs 采用基于超分子溶剂的微萃取（SUPRAS）方法提取，浓度采用高压液相色谱（HPLC）-荧光检测法测定。Σ16PAHs 浓度的平均值发现，餐厅最高（386.09±413.17mg/kg），其次是食堂（80.91±92.81mg/kg）和住宅（24.65±10.52mg/kg）。交通源被发现是餐厅 PAHs 的主要来源，而烹饪活动是食堂和住宅的来源。三环和五环 PAHs 在餐厅和食堂样品中较为突出，而二环和三环 PAHs 在住宅样品中贡献最大。接触这些 PAHs 产生的非癌症风险（危害指数）在安全范围内，即 2.70E-09 至 7.46E-08。接触这些 PAHs 的终生癌症风险估计范围为 2.46E-06 至 7.81E-04，表明由于超过 10 的指导值，存在显著风险。
