Leucanthemum vulgare lam. crude oil phytoremediation

Abstract

Sites with crude oil pollution have been successfully treated using phytoremediation, but expanding the range of plants that can be used and understanding how exposure impacts the plants are two areas of study that are important to continue. Leucanthemum vulgare has been shown to grow well under a variety of stressful conditions. To examine L. vulgare's ability to both survive crude oil exposure and to reduce crude oil concentrations in soil, plants were placed in soil containing 0, 2.5%, 5%, 7.5% or 10% w/w crude oil. Total Petroleum Hydrocarbons (TPH) concentration, peroxidase and catalase activity, proline and phenol content in roots and leaves were determined at the start of planting and every 2 months for six months. L. vulgare roots were successfully colonized with mycorrhizae under all conditions. Results showed positive correlation between antioxidant compound concentration and crude oil contamination. Also, a significant reduction occurred in TPH content of soil over time in planted pots as compared to controls. The lowest TPH content was recorded after 6 months under all treatments. Results showed L. vulgare could survive crude oil exposure and enhance reducing of crude oil from soil.

“…Similar findings were reported by Sivaram et al ( 2018 ), who compared C3 and C4 plants for the remediation of PAH-polluted soils and stated that the remediation of PAH-polluted soils not only depends on the physicochemical property of PAH but also depends on the nature of the plants and the biologically available concentration of PAH (Reid et al 2000 ; Sivaram et al 2018 ). Our results regarding PAH degradation are in agreement with the assumption of Noori et al ( 2018 ), who documented that the plant roots can facilitate the degradation of pollutants in the soil. They also suggested that PAH degradation could also be the result of plant enzymatic and biochemical activities, as well as the enhancement of microbial community activity in the rhizosphere.…”

“…Indeed, TPH are considered environmental stressors that can cover the plant root surface and prevent water and nutrient uptake. Moreover, they can enhance the production of reactive oxygen species (ROS), leading to the activation of oxidative stress in plants (Noori et al 2018 ).…”

“…Furthermore, as plants like other organisms produce ROS in response to abiotic and biotic stresses [55], environmental contamination arising from PH reduce the availability of essential nutrients (like nitrogen and oxygen) required for plant growth [19,56], including water [57] owing to the surface covering of the plant roots by the hydrophobic contaminant, thereby enhancing the production of ROS and hence, oxidative stress in plants [55,58].…”

Результаты показали, что L. vulgare может выживать в условиях загрязнения нефтепродуктами и способствовать уменьшению их содержания в субстрате [40]. В Иркутской области T. inodorum распространен в западной и южной частях Среднесибирского плоскогорья и на Южном побережье озера Байкал.…”
