A rapid and sensitive assessment of the toxicity of oxygenated polycyclic aromatic hydrocarbons (OPAHs), widely distributed persistent organic pollutants in the environment, is crucial for human health. In this study, using high-performance liquid chromatography, the separation and detection of four purines, xanthine (X), guanine (G), adenine (A), and hypoxanthine (HX) in cells were performed. The aim was to evaluate the cytotoxicity of three OPAHs, namely 1,4-benzoquinone (1,4-BQ), 1,2-naphthoquinone (1,2-NQ) and 9,10-phenanthrenequinone (9,10-PQ), with higher environmental concentrations, from the perspective of purine nucleotide metabolism in human skin fibroblast cells (HFF-1)...
