The potential of phytoremediation of oil-based drill cuttings (OBDCs) contaminated soil was assessed by measuring the level of petroleum hydrocarbons reduction. The contamination experiment was simulated in a randomized complete block design by factorial of 6 × 3 × 2 × 2 for grass species ( and ), drill cuttings treatments (0%, 25%, and 50% OBDCs contamination), time (0 day of planting and 105 days of harvesting), and growth stage (young and mature). The parameters assessed were total petroleum hydrocarbons (TPHs) in soils, roots, and shoots; bioconcentration factor in roots and shoots; and translocation factor. The TPH reductions achieved in 25% treatment level were young (58.01%), mature , young and (44.24%), young (27.67%), mature (25.29%), mature (2.56%), mature (4.01%), and unplanted soils (2.10%). Thus young and mature are recommended for TPH reduction in 25% OBDCs contaminated soils. Young and mature can be used to achieve 25% - 27% TPH reduction.
通过测量石油烃减少水平来评估植物修复油基钻屑（OBDCs）污染土壤的潜力。污染实验采用随机完全区组设计，以6×3×2×2析因法进行，因素包括草种（和）、钻屑处理（0%、25%和50% OBDCs污染）、时间（种植后0天和收获时105天）以及生长阶段（幼龄和成熟）。评估的参数包括土壤、根和地上部分的总石油烃（TPHs）；根和地上部分的生物富集系数；以及转运系数。在25%处理水平下实现的TPH减少率分别为：幼龄（58.01%）、成熟、幼龄和（44.24%）、幼龄（27.67%）、成熟（25.29%）、成熟（2.56%）、成熟（4.01%）以及未种植土壤（2.10%）。因此，推荐幼龄和成熟用于减少25% OBDCs污染土壤中的TPH。幼龄和成熟可用于实现25% - 27%的TPH减少。
