我们调查了16个优先多环芳烃（PAHs）在各种烧烤和烟熏食品的浓度和配置文件，并估计科威特儿童，青少年和成年人的饮食暴露。结果表明，非致癌性多环芳烃的比例很高（60-100%），菲的平均浓度最高（54.9 μ g kg（-1），占多环芳烃总浓度的37.1%）。在遗传毒性多环芳烃（PAH 8）中，金（4.88 μ g kg-1，3.29%）和苯并[a]蒽（2.27 μ g kg-1，1.53%）的平均值最高。肉tikka含有最高的平均浓度的苯并[a]芘（BaP）（2.48 μ g kg（-1）），总遗传毒性多环芳烃（42.9 μ g kg（-1）），总多环芳烃（Sigma PAHs）（648 μ g kg（-1））和总苯并[a]芘当量（Sigma BaPeq）（6.02 μ g kg（-1））。在烤蔬菜（21.1微克/千克）、香菇（20.5微克/千克）和整只烤鸡（20.3微克/千克）样本中检测到高水平的遗传毒性多环芳烃。然而，肉类和鸡肉shawerma样本的PAH 8水平较低。肉tikka（437 ng/天，641 ng/天），整个烤鸡（160 ng/天，241 ng/天），烤蔬菜（120 ng/天，166 ng/天），肉汉堡（114 ng/天，92.7 ng/天）分别是儿童/青少年和成人人群中PAH 8每日摄入量的主要贡献者。儿童/青少年和成人的BaP（8.09 ng/天，9.20 ng/天）、PAH 8（84.2 ng/天，95.7 ng/天）、Sigma PAHs（974 ng/天，1108 ng/天）和Sigma BaPeq（14.8 ng/天，16.8 ng/天）的总平均膳食摄入量相当。科威特儿童/青少年和成人从动物源性食物中摄入Sigma BaPeq的癌症风险分别为2.63/10（7）和9.3/10（7）。(C)2011爱思唯尔有限公司保留所有权利。
We investigated the concentrations and profiles of 16 priority polycyclic aromatic hydrocarbons (PAHs) in various grilled and smoked foods and estimated the dietary exposure of Kuwaiti children, adolescent and adult populations. Results indicated that non-carcinogenic PAHs were present at high proportions (60-100%) with phenanthrene showing the highest mean concentration (54.9 mu g kg(-1), 37.1% of the total PAH concentrations). Among the genotoxic PAHs (PAH8), chrysene (4.88 mu g kg(-1), 3.29%) and benz[a] anthracene (2.27 mu g kg(-1), 1.53%) showed the highest mean values. Meat tikka contained the highest mean concentrations of benzo[a]pyrene (BaP) (2.48 mu g kg(-1)), total genotoxic PAHs (42.9 mu g kg(-1)), total PAHs (Sigma PAHs) (648 mu g kg(-1)) and total benzo[a]pyrene equivalents (Sigma BaPeq) (6.02 mu g kg(-1)). High levels of genotoxic PAHs were detected in grilled vegetables (21.1 mu g kg(-1)), shish tauk (20.5 mu g kg(-1)) and whole grilled chicken (20.3 mu g kg(-1)) samples. However, meat and chicken shawerma samples had low levels of PAH8. Meat tikka (437 ng/day, 641 ng/day), whole grilled chicken (160 ng/day, 241 ng/day), grilled vegetables (120 ng/day, 166 ng/day), meat burger (114 ng/day, 92.7 ng/day) were the major contributors to the daily intake of PAH8 in children/adolescent and adult populations, respectively. The total mean dietary intakes for children/adolescents and adults for BaP (8.09 ng/day, 9.20 ng/day), PAH8 (84.2 ng/day, 95.7 ng/day), Sigma PAHs (974 ng/day, 1108 ng/day) and Sigma BaPeq (14.8 ng/day, 16.8 ng/day) were comparable. Cancer risks for Kuwaiti children/adolescents and adults from dietary intake of Sigma BaPeq from the animal-origin foods were determined to be 2.63/10(7) and 9.3/10(7), respectively.
