Pollution generated from landfill solid wastes constitute one of the major threat to the environment. The landfill leachate contains various toxic pollutants, making it the most dangerous issue of the landfills. Monitoring the xenobiotic organic concentrations in landfill leachate is an important step to evaluate the environmental impacts. This work aims to characterize the seasonal variation of 55 xenobiotic organic compounds including polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), phthalic acid esters (PAEs) and bisphenols (BPs) in the leachate from municipal solid waste landfill of Tripoli, Lebanon. And also, the quantity of the pollutant's flux to the Abou Ali River and the Mediterranean Sea nearby has been estimated. The organic pollutants were extracted by using the solid-phase extraction and quantified by using GC-MS/MS. The results showed high level of PAEs, BPs, PCBs, and PAHs in the leachate samples. The fluxes of pollutants to the Abou Ali River and Mediterranean Sea have been detected at 0.23 kg, 0.01 kg, 116.85 kg, 15.93 kg, and 7.58 kg for ΣPAHs, ΣPCBs, ΣPAEs, ΣBPs, and 4-NP respectively.
垃圾填埋场产生的污染是对环境的主要威胁之一。垃圾渗滤液含有各种有毒污染物，是垃圾填埋场最危险的问题。监测垃圾渗滤液中外来有机污染物的浓度是评估环境影响的重要步骤。本工作旨在描述黎巴嫩的黎波里市垃圾填埋场渗滤液中 55 种异源有机化合物（包括多环芳烃（PAHs）、多氯联苯（PCBs）、邻苯二甲酸酯（PAEs）和双酚（BPs））的季节性变化，并估计污染物通量到附近的阿卜阿里河和地中海。采用固相萃取法提取有机污染物，并用 GC-MS/MS 定量。结果表明，渗滤液样品中 PAEs、BPs、PCBs 和 PAHs 含量较高。检测到污染物向阿卜阿里河和地中海的通量分别为 ΣPAHs、ΣPCBs、ΣPAEs、ΣBPs 和 4-NP 的 0.23kg、0.01kg、116.85kg、15.93kg 和 7.58kg。
