对2008年11月至12月期间在西班牙加泰罗尼亚随机购买的各种食品中16种多环芳烃(PAH)的浓度进行了检测。随后，根据年龄和性别对加泰罗尼亚普通人群的多环芳烃饮食摄入量进行了估计。目前的结果与2000年和2006年进行的先前研究的结果进行了比较。多环芳烃含量最高的是菲(18.18 mU g/kg)、萘(13.31 mU g/kg)和芘(8.46 mU g/kg)，最低的是二苯并[a，h]菲(0.89 mU g/kg)、并[1，2，3-c，d]芘(0.94 mU g/kg)和苯并[k]荧菲(1.00 mU g/kg)。在总致癌多环芳烃中，苯并[a]芘的贡献率为47.77%或48.22%，具体取决于所用的TEF值。按食品类别划分，目前在肉类及肉制品中检出的总多环芳烃含量最高(38.99微克/公斤)，其次是油脂(18.75微克/公斤)和乳制品(7.57微克/公斤)。对多环芳烃膳食摄入量贡献最大的是肉及肉制品组(4.75 mg/d)。标准成年男性(体重70公斤)的平均膳食摄入量估计为6.72微克/天，低于我们2000年(8.42微克/天)和2006年调查(12.04微克/天)的结果。就最近其他研究的结果而言，目前的多环芳烃浓度相对较低。(C)2010爱思唯尔有限公司。保留所有权利。
The concentrations of 16 polycyclic aromatic hydrocarbons (PAH) were determined in various foodstuffs randomly purchased in Catalonia (Spain) during November and December of 2008. Dietary intake of PAH was subsequently estimated according to age and sex for the general population of Catalonia. The current results were compared with those of previous studies performed in 2000 and 2006. The highest PAH levels corresponded to phenanthrene (18.18 mu g/kg), naphthalene (13.31 mu g/kg), and pyrene (8.46 mu g/kg), whereas the lowest concentrations were those of dibenzo[a,h]anthracene (0.89 mu g/kg), indeno[1,2,3-c,d]pyrene (0.94 mu g/kg), and benzo[k]fluoranthene (1.00 mu g/kg). With respect to the contribution of total carcinogenic PAH, benzo[a]pyrene contributed 47.77% or 48.22%, depending on the TEF value used. By food groups, the current highest levels of total PAH were detected in meat and meat products (38.99 mu g/kg), followed by oils and fats (18.75 mu g/kg), and dairy products (7.57 mu g/kg). The highest contribution to PAH dietary intake corresponded to the group of meat and meat products (4.75 mu g/day). The estimated mean dietary intake for a standard male adult (70-kg body weight) was 6.72 mu g/day, a lower value than those found in our 2000 (8.42 mu g/day), and 2006 surveys (12.04 mu g/day). With regard to the results of other recent studies, the current PAH concentrations were comparatively lower. (C) 2010 Elsevier Ltd. All rights reserved.
