通过析因试验研究了7种杂酚油相关化合物（菲、芴、对甲酚、五氯酚、咔唑、二苯并噻吩和二苯并呋喃）在地下水中好氧生物降解过程中的相互作用。分别以菲、对甲酚和咔唑为第一、第二和第三次实验的响应变量，以其他化合物为影响因素，在简单批处理体系中进行了三个独立的实验。一般来说，疏水和难溶性越强的化合物受底物相互作用的影响越大。对甲酚的矿化不受底物相互作用的影响。对甲酚对菲的矿化有抑制作用，而其他化合物对咔唑的矿化无抑制作用，其他化合物的存在严重影响咔唑的矿化。对甲酚为主要抑制剂。菲抑制了咔唑的生物降解，但抑制程度较轻，而芴则增强了咔唑的矿化。五氯酚和二苯并呋喃使滞后时间增加，但对咔唑矿化无影响。
The interactions among seven creosote-related compounds (phenanthrene, fluorene, p-cresol, pentachlorophenol, carbazole, dibenzothiophene, and dibenzofuran) during their aerobic biodegradation in groundwater were studied in factorial experiments. Three separate experiments were conducted in simple batch systems with phenanthrene, p-cresol, and carbazole as the response variable for the first, second, and third experiments, respectively, and other compounds as factors. In general, the more hydrophobic and recalcitrant compounds were more affected by substrate interaction. Mineralization of p-cresol was not affected by substrate interaction. In contrast, p-cresol inhibited mineralization of phenanthrene, but other compounds did not Mineralization of carbazole was severely affected by the presence of other compounds. p-Cresol was the main inhibitor. Phenanthrene inhibited biodegradation, butto a lesser extent, whereas fluorene enhanced mineralization of carbazole. Pentachlorophenol and dibenzofuran caused an increase in the lag time but did not affect mineralization of carbazole afterward.
