Concentrations of benzene, toluene, C2-benzenes and styrene were determined in olives and the oils produced thereof, as well as at various intermediate steps during production. Concentrations were compared to those found in samples of air taken from the olive grove and the olive mills. In an exposition experiment in the laboratory, olives absorbed aromatic compounds, approaching saturation corresponding to the partition coefficient between air and oil. However, concentrations in olives delivered to the mills were 4-10 times higher than expected from the analysis of the air in the olive grove. In the olive mills, concentrations were increased further by a factor of up to 2 because of uptake from air which contained high concentrations of aromatics. Styrene concentrations strongly increased during storage of crushed olives at ambient temperature, which confirms the hypothesis that styrene is a product of metabolism.
测定了橄榄及其所产橄榄油中苯、甲苯、C2 - 苯类化合物和苯乙烯的浓度，以及生产过程中各个中间步骤的这些物质浓度。将这些浓度与从橄榄园和橄榄油厂采集的空气样本中的浓度进行了比较。在实验室的暴露实验中，橄榄吸收芳香族化合物，接近与空气和油之间分配系数相对应的饱和状态。然而，送到橄榄油厂的橄榄中的浓度比根据橄榄园空气分析预期的浓度高4至10倍。在橄榄油厂，由于从含有高浓度芳香族化合物的空气中吸收，浓度进一步增加了高达2倍。在室温下储存压榨后的橄榄期间，苯乙烯浓度大幅增加，这证实了苯乙烯是代谢产物的假设。
