| Abstract: | The main aim of this study is to analyze both domestic and imported marine products in Korea for 14 sulfonamide antimicrobials. Monitoring samples included flatfish, jacopever, sea bream, common eel, blue crab, shrimp, and abalone. In analyzing step, the residues of 14 sulfonamides (SAs) were determined by high-performance liquid chromatography (HPLC) with photodiode array detector. And in confirmatory step, ultra-performance liquid chromatography-tandem mass spectroscopy (UPLC-MS/MS) was used for unequivocal identification of target compounds.No sulfonamide antimicrobials were found in more than 99% of the samples analyzed in this study. The monitoring results revealed that sulfadiazine was detected in two samples (flatfish and jacopever) below the maximum residue limit (MRL), 100 ?/㎏ as the sum of 14 sulfonamides. Of samples, one common eel containing sulfamethoxazole above the legal residue limit was found, and the detected concentration was 5104 ?/㎏. |
