During the burning of the organic material (firewood) in the drying, combustion may occur incompletely, thus generating smoke contaminants such as polycyclic aromatic hydrocarbons (PAHs) in the furnaces. This study aimed to identify possible contamination by PAHs in soybean grains from storage units in municipalities in the Midwest region that have undergone drying in a direct-fired furnace with firewood as fuel. The soybean grains were collected in different municipalities of the Midwest region of Brazil, totaling 22 samples. A survey of possible contamination of soybean grains by PAHs was carried out using High-Performance Liquid Chromatography. The experiment was carried out in a completely randomized design with three replicates, and the data were subjected to analysis of variance, with means compared by Tukey test. The sum of the groups was: PAH4 - 1.45 μg kg for Edéia (2), PAH8 - 2.97 μg kg for Catalão (19) and PAHT - 5.06 μg kg for Edéia (2); for benzo(a)pyrene, the sum was below 2.0 μg kg, not exceeded by the value of 0.64 μg kg for Edéia (1). The values found of PAHs did not exceed the maximum limits established by the European Union, except for infant food.
在干燥过程中燃烧有机材料（木柴）时，燃烧可能不完全，从而在炉中产生多环芳烃（PAHs）等烟雾污染物。本研究旨在确定巴西中西部地区以木柴为燃料的直燃炉干燥后的储存单元中大豆籽粒PAHs的可能污染情况。大豆籽粒采自巴西中西部地区的不同城市，共22个样本。采用高效液相色谱法对大豆籽粒PAHs的可能污染情况进行了调查。实验采用完全随机设计，重复三次，数据进行方差分析，均值通过Tukey检验进行比较。各组的总和为：埃代亚（2）的PAH4为1.45 μg/kg，卡塔朗（19）的PAH8为2.97 μg/kg，埃代亚（2）的PAHT为5.06 μg/kg；对于苯并（a）芘，总和低于2.0 μg/kg，埃代亚（1）的0.64 μg/kg未超过该值。除婴儿食品外，所发现的PAHs值未超过欧盟规定的最大限量。
