An analytical method for the biomonitoring of arsenic, benzene and polycyclic aromatic hydrocarbons (PAHs) in human urine was developed using liquid chromatography tandem mass spectrometry (LC-MS/MS). The urinary metabolites of monomethylarsonic acid (MMAA), dimethylarsonic acid (DMAA), s-phenylmercapturic acid (S-PMA), and
