The effects of unprocessed olive mill wastewaters (OMW) on soil characteristics were investigated. Phenolic compounds levels in the treated soil were compared to those of a control soil profile. Results showed that OMW infiltration caused a modification of soil physicochemical characteristics. Phenolic compounds were detected at a depth of 1.2m four months after the last application of OMW. A moderate phytotoxic residual phenolic fraction (F) was extracted from the superficial soil layer 1 year after the OMW application. This residual F had a phytotoxic potential comparable to that of 25-fold diluted OMW.
研究了未处理的橄榄果渣废水（OMW）对土壤特性的影响。将处理后土壤中的酚类化合物水平与对照土壤剖面的酚类化合物水平进行了比较。结果表明，OMW渗入导致土壤理化特性发生改变。在最后一次施用OMW四个月后，在1.2米深处检测到酚类化合物。在施用OMW一年后，从表层土壤层中提取出了具有中等植物毒性的残留酚类组分（F）。这种残留F的植物毒性潜力与稀释25倍的OMW相当。
