A total of 13 polycyclic aromatic hydrocarbons (PAHs) were surveyed in dry whole soybeans (Glycine max L.) sold for human consumption. The analysed samples were commercialised in vegetarian shops and food stores in Southern Brazil regions. The determination of PAHs levels was carried out by high performance liquid chromatography (HPLC)with fluorescence detection. PAHs were present in 89.7% of the samples. Chrysene (Chy) and 5 methyl chrysene (5MeChy) were the main PAHs detected (76.9% and 71.8%, respectively) followed by dibenzo(ai)pyrene (DaiP), however in a much less percentage of samples (23.1%). Apart from those PAHs, also benzo(a)antracene (BaA), benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF) and benzo(a)pyrene(BaP) were found. The ΣPAH levels in the positive samples ranged from 0.80 to 38.78 µg kg, with exception of one sample that reached 204.46 µg kg (ΣPAHs of six compounds). Despite the present contamination there are no maximum limits set for PAHs in soybeans.
对市售供人类食用的干大豆（Glycine max L.）中的13种多环芳烃（PAHs）进行了调查。分析的样品在巴西南部地区的素食商店和食品店中销售。采用高效液相色谱法（HPLC）结合荧光检测法测定PAHs含量。89.7%的样品中存在PAHs。检测到的主要PAHs是 Chrysene（Chy）和5-甲基 Chrysene（5MeChy）（分别为76.9%和71.8%），其次是二苯并（a，i）芘（DaiP），不过其在样品中的占比要低得多（23.1%）。除了这些PAHs，还发现了苯并（a）蒽（BaA）、苯并（b）荧蒽（BbF）、苯并（k）荧蒽（BkF）和苯并（a）芘（BaP）。阳性样品中的ΣPAH含量范围为0.80至38.78 μg/kg，有一个样品除外，其含量达到204.46 μg/kg（六种化合物的ΣPAHs）。尽管存在这种污染情况，但目前大豆中PAHs没有设定最大限量。
