Polycyclic aromatic hydrocarbons (PAHs) are a serious threat to the health of the environment. This study investigated the potential of for the uptake, accumulation, and biodegradation of phenanthrene and pyrene. plants were treated with 10 and 30 mg L concentrations of phenanthrene and pyrene for the experimental duration of ten days. Phenanthrene and pyrene concentrations were measured using the high-performance liquid chromatography (HPLC) technique. Identification of the intermediate by-products resulting from the biological degradation of PAHs was performed by gas chromatography-mass spectrometry (GC/MS). The quantities of phenanthrene and pyrene in the ten-day treatments with 10 and 30 mg L were 0.007 and 0.011 mg g FW, and 0.048 and 0.079 mg g FW, respectively. The growth parameters in the plants such as fresh weight, dry weight and RFN as well as the content of photosynthetic pigment of the plant decreased significantly compared to the control sample ( < 0.05). Ten compounds were identified from the plant tissue during the decomposition of pyrene and phenanthrene, and none of the PAHs were identified in the aquatic environment. Therefore, the use of for phytoremediation of water resources contaminated with PAHs is an effective and promising method.
多环芳烃（PAHs）对环境健康构成严重威胁。本研究探讨了 对菲和芘的吸收、积累和生物降解的潜力。在实验期间的十天内，用 10 和 30mg/L 的菲和芘浓度处理 植物。使用高效液相色谱（HPLC）技术测量菲和芘的浓度。通过气相色谱-质谱联用（GC/MS）技术鉴定了生物降解 PAHs 产生的中间副产物。在 10 和 30mg/L 浓度的十天处理中，菲和芘的含量分别为 0.007 和 0.011mg/gFW 和 0.048 和 0.079mg/gFW。与对照样品相比（ < 0.05），植物的生长参数（如鲜重、干重和 RFN）以及植物的光合色素含量显著下降。在菲和芘分解过程中从植物组织中鉴定出了 10 种化合物，而在水生环境中未鉴定出任何 PAHs。因此，利用 进行受多环芳烃污染的水资源的植物修复是一种有效且有前途的方法。
