PHYTOREMEDIATION OF CONTAMINATED SOIL WITH ANTHRACENE USING SUNFLOWER (HELIANTHUS ANNUUS)
ISMAIL AL-HUNITY
Abstract
Anthracene is a polycyclic aromatic hydrocarbon (PAH) that is formed primarily by incomplete combustion of fossil fuels as a result of anthropogenic activities.These compounds are hazardous to both human health and the environment.A phytoremediation experiment in pots was carried out in this study to assess the ability of Sunflower (Helianthus annuus) to remediate anthracene-contaminated soil at various concentrations.After artificial contamination, the anthracene concentrations (mg/kg) in the soils were C1 (1.56mg/kg), C2 (160.56mg/kg), and C3 (320.56mg/kg).After 86 days of phytoremediation, anthracene levels were significantly higher in the cultivated contaminated soil (42.79%) than in the unplanted contaminated soil (20.76%) at C2 treatment.. However, the results showed that sunflowers significantly improved anthracene dissipation in the soil.The sunflower also accumulated the tested anthracene in its tissues.The levels of contaminants in the soils caused this buildup to rise.Additionally, compared to its underground portion, the sunflower's stalk and disc gathered more anthracene (root).The findings of this study showed that employing sunflowers in the phytoremediation procedure is an efficient way to clean up anthracene-contaminated soils.
