The purpose of this research was to evaluate the concentrations, sources and ecological risk assessment of sixteen polycyclic aromatic hydrocarbons (PAHs) present in water from the La Fe reservoir, Colombia in the months of October and November of 2017 and 2018. Concentrations of PAHs in water were measured with semipermeable membrane devices (SPMD) which allow obtaining the dissolved concentrations of the PAHs in the reservoir, emphasizing the reactivity and bioavailability in the environment. The PAHs analyses were carried out by means of gas chromatography, coupled with tandem mass spectrometry (GC/MS–MS) with triple quadrupole (QqQ). The environmental risk assessment using the estimation of risk quotient with deterministic and probabilistic method, the predictive no-effect concentration (PNEC) and environmental exposure concentration (EEC) in water indicate a negligibe risk for probabilistic method for all PAHs evaluated (RQ < 0.1).

本研究的目的是评估 2017 年 10 月和 11 月和 2018 年哥伦比亚 La Fe 水库水中存在的 16 种多环芳烃 (PAH) 的浓度、来源和生态风险评估。使用半透膜装置 (SPMD) 测量水，该装置允许获得水库中 PAH 的溶解浓度，强调环境中的反应性和生物利用度。PAHs 分析通过气相色谱法和串联质谱法 (GC/MS-MS) 与三重四极杆 (QqQ) 进行。使用确定性和概率方法估计风险商的环境风险评估，
