Abstract：Quinolone antibiotics in vegetables from Dongguan vegetable farms were determined using ultra high performance liquid chromatography-tandem mass spectrometry and the health risk of their exposure to human body by diet pathway was assessed. The results showed that quinolone antibiotics in the vegetable samples were frequently detected. Norfloxacin and ciprofloxacin were main compounds,followed by enrofolxacin, and the three antibiotics were detected in more than 80% of the samples.The highest content of individual compounds was more than 100μg/kg (D.W.) and average contents was around 20μg/kg (D.W.). The composition and concentration of quinolone antibiotics in various farms of vegetables and different kinds of vegetables varied greatly, with the order of leafy vegetable (49.87μg/kg) >rhizome vegetable (44.81μg/kg)> melon-fruit vegetable (11.21μg/kg). The intake dose of quinolone antibiotics via the consumption of vegetable from Dongguan farms was lower than acceptable daily intake (ADI), suggesting a lower health risk.
