在一段时间的2.5年，221种不同的食品的“市场篮子”的18岁的男性购买每3个月。总共收集了10个市场篮子。这些食品按常规方法制备，并组合成23个商品组。从每个商品组中制备匀浆，然后分析17种不同的多环芳烃。所有这些化合物都被检测到。最常见的多环芳烃是苯并[B]荧蒽、荧蒽和苯并[k]荧蒽，分别占59%、48%和46%。在“糖和糖果”商品组中，单一多环芳烃的最高浓度为36微克金/千克。根据总饮食样本中的浓度，计算了各种多环芳烃的每日可能摄入量。分析的总PAH组分的平均每日摄入量在5 μg/天（低估计值）和17 μg/天（高估计值）之间。致癌PAH部分的摄入量大约是这些量的一半。每日PAH摄入量的最大贡献来自糖和糖果，谷物，油，脂肪和坚果。
Over a period of 2.5 yr, 221 different food items of a ‘market basket’ of 18-yr-old males were purchased every 3 months. In total, 10 market baskets were collected. The foodstuffs were prepared by normal methods and combined into 23 commodity groups. Homogenates were prepared from each commodity group, followed by analysis for 17 different polycyclic aromatic hydrocarbons (PAHs). All these compounds were detected. The most frequently occurring PAHs were benzo[b]fluoranthene, fluoranthene and benzo[k]fluoranthene, in 59, 48 and 46% of the samples, respectively. The highest concentration of a single PAH was 36 μg chrysene/kg in the commodity group ‘sugar and sweets’. On the basis of concentrations found in the total diet samples the possible daily intakes of the various PAHs were calculated. The mean daily intake of the total PAH fraction analysed was between 5 μg/day (low estimate) and 17 μg/day (high estimate). The intake of the carcinogenic PAH fraction was roughly half these amounts. The largest contribution to the daily PAH intake came from sugar and sweets, cereals, oils, fats and nuts.
