The study investigated the effects of Jatropha curcas (JC) and Vetiveria zizanioides (VZ) on hydrocarbon concentration levels in mine spoils. A 2 × 2 × 3 factorial arrangement of treatments in a completely randomized design with 3 replications was adopted. With compost amendments, JC caused 78.8 and 82.2% and VZ caused 51.1 and 39.7% decline in soil TPH and TOG concentrations, respectively after 16 weeks. Compost amendments significantly reduced TOG and TPH concentrations compared to the other treatments in both JC and VZ (p < 0.0001). However, the effect of species on TOG and TPH concentrations were marginally significant (p = 0.081 and p < 0.006, respectively). Growth in height, collar diameter and number of leaves in JC were significantly higher in the compost amendment compared to the fertilizer and control treatments (p < 0.0001). Number of leaves (p = 0.009) and collar diameter growth (p = 0.010) were significantly lower in contaminated soils compared to non-contaminated soils. Furthermore, only the number of tillers in Vetiver was significantly influenced by the soil amendments (p = 0.003) and the soil hydrocarbon levels (p = 0.048). It is concluded that phytoremediation particularly with JC is an alternate means to reducing soil hydrocarbon concentration levels. However, soils must be amended with compost for effective remediation and rapid, vigorous, early growth of plants.

加纳锰业有限公司用两种植物对植物进行的石油烃污染土壤的植物修复:麻疯树和香根草

该研究调查了麻疯树(JC)和香根草(VZ)对矿渣中碳氢化合物浓度的影响。在完全随机的设计中采用2×2×3的阶乘安排处理,重复3次。经过堆肥修正,在16周后,JC导致土壤TPH和TOG浓度分别下降78.8和82.2%,VZ导致土壤TPH和TOG浓度下降51.1和39.7%。与JC和VZ中的其他处理相比,堆肥改良剂显着降低了TOG和TPH浓度(p  <0.0001)。但是,物种对TOG和TPH浓度的影响略有显着性(p  = 0.081和p 分别<0.006)。与肥料和对照处理相比,堆肥改良中JC的高度,衣领直径和叶片数增长显着更高(p  <0.0001)。 与未污染的土壤相比,被污染的土壤的叶片数(p  = 0.009)和领径增长(p = 0.010)显着降低。此外,土壤改良剂(p  = 0.003)和土壤碳氢化合物含量(p = 0.048)。结论是,特别是用JC进行植物修复是降低土壤碳氢化合物浓度水平的另一种方法。但是,必须使用堆肥对土壤进行改良,以有效修复植物并使其快速,有力地早期生长。
