“…Diesel had only a negligible (3.1%) inhibiting effect on the growth rate of M. sativa, while M. albus in diesel-contaminated soil grew up to 39.9% slower than those in control soil. High L. corniculatus and M. lupulina tolerance to diesel were also confirmed by Pawluśkiewicz et al (2020) [58], though T. repens showed higher sensitivity. Good M. sativa tolerance to diesel was found in the study by Hawrot-Paw et al (2015) [59], where 19 plant species' responses to diesel were analysed.…”

This study aims to assess the impact of HydroBreak PLUS biosurfactant on the phytoremediation of diesel-contaminated soil by three legume plant species: Medicago sativa, Lotus corniculatus, and Melilotus albus. Legumes were grown in soil contaminated with diesel (4.0 g kg−1, 6.0 g kg−1) for 90 days, and the changes in soil diesel and nutrient concentrations, plant growth, and physiological parameters were measured. Diesel negatively affected the biomass production of all legumes, though the reduction in growth rate was observed only in L. corniculatus and M. albus. L. corniculatus had the highest diesel removal rate of 93%, M. albus had the lowest of 87.9%, and unplanted treatments had significantly lower diesel removal rates (up to 66.5%). The biosurfactant mitigated diesel-induced reduction in plant shoot and root weight and an increase in L. corniculatus root biomass (24.2%) were observed at 4.0 g kg−1 diesel treatment. The use of biosurfactant accelerated diesel removal from the soil, though the effect was diesel soil concentration and plant species-dependent. In unplanted treatments, the diesel removal rates increased by 16.4% and 6.9% in the treatments with 4 and 6 mg kg−1, respectively. The effect of biosurfactants on diesel removal by plants was less pronounced and reached 4.6% and 3.2% in the treatments with 4 and 6 mg kg−1, respectively. The study revealed that the phytoremediation efficiency could not be directly linked to plant physiological parameters as only M. sativa changes in plant growth corresponded well with photosystem II performance. Implementation of legumes and biosurfactants has a positive effect on soil quality by its enrichment with inorganic P and soluble phenols, while no enrichment in NO3− and NH4+ was observed.

“…This response could be related to the fact that Juncus species subjected to salt in the grown solution trend to reduce their growth in order to activate some defense mechanisms [ 29 ]. Pawluśkiewicz et al [ 19 ] found that diesel induces a defense mechanism in which plants extend their cells in order to increase the radicle surface and develop new root hairs due to oil causing clogging of the vascular cells, used for water intake. A reduction in growth induced by the higher NaCl concentration tested could lead to an inhibition of the root development.…”

“…However, plants are very sensitive and respond rapidly to diesel presence [ 18 ]. Therefore, it is important to identify plants capable of growing in diesel-contaminated soils [ 19 ]. Juncus species have been proposed as a bio-tool for wetland restoration projects around the world [ 20 , 21 ] due to their ability to cope with heavy metals [ 22 , 23 , 24 ] and petroleum-derived substances such as diesel [ 25 ].…”

Soil contamination with petroleum-derived substances such as diesel fuel has become a major environmental threat. Phytoremediation is one of the most studied ecofriendly low-cost solutions nowadays and halophytes species has been proved to have potential as bio-tools for this purpose. The extent to which salinity influences diesel tolerance in halophytes requires investigation. A greenhouse experiment was designed to assess the effect of NaCl supply (0 and 85 mM NaCl) on the growth and photosynthetic physiology of Juncus acutus plants exposed to 0, 1 and 2.5% diesel fuel. Relative growth rate, water content and chlorophyll a derived parameters were measured in plants exposed to the different NaCl and diesel fuel combinations. Our results indicated that NaCl supplementation worsened the effects of diesel toxicity on growth, as diesel fuel at 2.5% reduced relative growth rate by 25% in the absence of NaCl but 80% in plants treated with NaCl. Nevertheless, this species grown at 0 mM NaCl showed a high tolerance to diesel fuel soil presence in RGR but also in chlorophyll fluorescence parameters that did not significantly decrease at 1% diesel fuel concentration in absence of NaCl. Therefore, this study remarked on the importance of knowing the tolerance threshold to abiotic factors in order to determine the bioremediation capacity of a species for a specific soil or area. In addition, it showed that NaCl presence even in halophytes does not always have a positive effect on plant physiology and it depends on the pollutant nature.

“…Because of their low density, higher viscosity and lower emulsifying ability, PHs are easily absorbed on the surface of the ground, increasing the soil water repellency (SWR) (Neil & Si, 2018). This contributes to the reduction of soil wettability and free capillary flow, limiting the access of plants to rainwater (Kraemer et al, 2019; Li et al, 2019; Pawluśkiewicz et al, 2020; Wei et al, 2019). SWR, along with reduced water sorptivity ( S w ) and hydraulic conductivity, can lead to increased surface runoff and erosion (Hewelke, 2019; Wang et al, 2000).…”

Influence of contamination with diesel oil on water sorptivity and hydrophobicity of sandy loam soil

et al. 2023

This paper shows the changes in water sorptivity (S w ) and hydrophobicity following soil contamination with petroleum hydrocarbons (PHs) under different soil moistures.Laboratory experiments were carried out to verify that contamination with PHs reduces S w , thus affecting the infiltrability, which in practice influences the field water capacity and the availability of water for plants. Soil water repellency (SWR) was estimated by the repellency index (R) and water drop penetration time (WDPT).The increase in PHs contamination contributed to SWR and caused a significant decrease in S w . With the decrease in moisture, the water sorptivity of the soil increased, reaching its maximum at 0.12-0.15 cm 3 cm À3 , which was the threshold value in the case of the analysed soil, and then decreased drastically. The R index and the WDPT revealed a similar trend, inversely related to the level of soil contamination with PHs. The increase in SWR and the accompanying decrease in S w made the soil less resistant to drought. The total amount of water available to plants in the control soil was 19.04%, whereas contamination with PHs equal to 100 g kg À1 caused a decrease to 6.36%. The almost threefold decrease in the total amount of water has a fundamental influence on increasing the risk of soil drought. The results obtained indicated that the interrelationship presented between the level of contamination with PHs, water sorptivity, SWR and soil moisture are the keys to predicting the environmental effects of contamination with PHs. The obtained results indicate that the undertaken remediation measures aimed at restoring the hydrological function of the soil system should be preceded by an assessment of soil hydrophobicity.
