Polycyclic aromatic hydrocarbons (PAHs) are semi-volatile anthropogenic contaminants that can damage soil fertility and threaten the environment due to their hazardous effects on various ecological parameters. The experimental objective was divided into two parts because PAHs are always present in mixtures. The toxicity of anthracene, phenanthrene, pyrene, and fluoranthene was examined and investigated the potential of three phytoremediator plants species viz , , and for remediation and translocation of individual PAH. PAHs were shown to have inhibitory or stimulating effects on growth, antioxidant properties, and impact on the structure of plant cells. The result showed that significantly enhances the removal rate of PAHs in the soil. The dissipation rate reached 96.2% in planted soil, followed by and . Among the plant species, exhibited the highest root and shoot concentrations (314.37 and 169.55 mg kg), while the lowest concentration was 187.56 and 76.60 mg kg in . SEM-EDX and fluorescence micrographs confirmed that pyrene altered plant tissue's ultrastructure and cell viability and was found to be the most toxic and resistant. was proven to be the most effective plant for the mitigation of PAHs.
多环芳烃（PAHs）是半挥发性人为污染物，由于它们对各种生态参数具有有害影响，会损害土壤肥力并威胁环境。由于PAHs总是以混合物形式存在，实验目标分为两部分。研究了蒽、菲、芘和荧蒽的毒性，并研究了三种植物修复植物物种，即[此处原文未给出具体植物名称]对单个PAH的修复和转运潜力。PAHs对植物生长、抗氧化特性以及植物细胞结构均显示出抑制或刺激作用。结果表明，[此处原文未给出具体植物名称]显著提高了土壤中PAHs的去除率。在种植[此处原文未给出具体植物名称]的土壤中，消散率达到96.2%，其次是[此处原文未给出具体植物名称]和[此处原文未给出具体植物名称]。在植物物种中，[此处原文未给出具体植物名称]的根和地上部分浓度最高（分别为314.37和169.55 mg/kg），而[此处原文未给出具体植物名称]中的浓度最低，分别为187.56和76.60 mg/kg。扫描电子显微镜-能谱仪（SEM-EDX）和荧光显微镜照片证实，芘改变了植物组织的超微结构和细胞活力，并且被发现是毒性最强且最具抗性的。[此处原文未给出具体植物名称]被证明是减轻PAHs最有效的植物。
