“…Diesel oil decreases the biomass yield of plants, and its effects are exacerbated with an increase in soil pollution (Leewis et al 2013 ; Xi et al 2018 ; Xie et al 2018 ; Petrová et al 2017 ; Bamgbose and Anderson 2015 ; Villacís et al 2016 ). In our study, increasing doses of diesel oil reduced the biomass yield of European beech only.…”

Research into trees plays a very important role in evaluations of soil contamination with diesel oil. Trees are ideal for reclaiming contaminated soils because their large biomass renders them more resistant to higher concentrations of pollutants. In the literature, there is a general scarcity of long-term studies performed on trees, in particular European beeches. The aim of this study was to evaluate the responses of Scots pines and European beeches grown for 8 years on soil contaminated with diesel oil. Selected morphological and physiological parameters of trees were analyzed. The biomass yield of Scots pines was not significantly correlated with increasing concentrations of diesel oil, but it was more than 700% higher than in European beeches. Scots pines were taller and had a larger stem diameter than European beeches during the 8-year study. The diameter of trees grown on the most contaminated soil was reduced 1.5-fold in Scots pines and more than twofold in European beeches. The length of Scots pine needles from the most contaminated treatment decreased by 50% relative to control needles. The shortest needles were heaviest. The fluctuating asymmetry (FA) of needle length was highest in Scots pines grown on the most contaminated soil, whereas the reverse was noted in the FA of needle weight. Diesel oil decreased the concentrations of chlorophylls a and b , total chlorophyll, and carotenoids. The Fv/Fm ratio of needles and leaves was influenced by the tested concentrations of diesel oil. The results of the study indicate that the Scots pine better adapts (grows more rapidly and produces higher biomass) to long-term soil contamination with diesel oil than the European beech. In European beeches, growth inhibition and leaf discoloration (a decrease in chlorophyll content) were observed already after the first year of the experiment, which indicates that 1-year-old seedlings of European beech are robust bioindicators of soil contamination with diesel oil.

“…Mixed plants must be able to absorb specific pollutants, for example cadmium which is related to plant species, but zinc is associated with soil [11]. Similar results were obtained in remediation of soil contaminated with some heavy metals and oils [12][13][14]. In addition, each plant must be able to work synergistically, including with root bacteria [2,3].…”

In this article, a theoretical approach is focusing on the use of mixed plants to remediate polluted environmental media. Essential conditions should be performed, particularly in supporting plant growth, the safety factor for consumers and the use of amendments in improving the efficiency of phytoremediation. In general, it takes more than one type of the plant to be more effective in restoring a polluted environment. For this purpose, the selected plant species mus synergistically eliminate the types of pollutants present in the environmental media. Thus, the mixed plants process becomes very effective in removing many of the pollutants on site. In practice, mixed plants operations could be selected from one or a combination of simultaneous, sequential or alternating patterns, all of which must be adapted to polluted media conditions.

“…Moreover, the hydrophobic properties of petroleum compounds hinder the absorption of the water, nutrients, and oxygen required by plants (Fernández et al 2011;Hussain et al 2018b;Taheri et al 2018). Xi et al (2018) reported that residual soil diesel content increased, while the removal ratio decreased at higher initial diesel concentrations.…”

To assess the ability of tall fescue (Festuca arundinacea) and grass pea (Lathyrus sativus) plant species in phytoremediation by the utilization of freshwater and urban wastewater, greenhouse experiments were conducted in 2018 and 2019 with three diesel-contaminated soil levels of 0, 1.5, and 3% w/w (DC, D1.5, D3, respectively). The maximum of soil diesel removal of tall fescue was by freshwater (54% (2018); 46% (2019)) and in the grass, the pea was by wastewater (44% (2018); 41% (2019)). A significant difference was observed in the amount of diesel removal by the plants at two levels of contamination, but the type of irrigation water had no significant effect. The plant growth decreased significantly by diesel increased in all treatments except D1.5 of tall fescue-2018 that led to better growth compared to the DC treatment. Diesel concentration had significant effects on the plant parameters (dry weight, height, color, time of flowering, and podding), but the types of water had no similar impact. Phytoremediation was considered an effective method to reduce soil contamination, but treated wastewater could not significantly improve phytoremediation performance. The correlation coefficient indicated that the diesel removal rate was positively correlated with the plant height and shoot dry weight (p < 0.01).
