Occurrence and human health risks of twenty-eight common antibiotics in wild freshwater products from the Xiangjiang River and comparison with the farmed samples from local markets

The occurrence of 28 common antibiotics in wild and farmed aquatic products from different species was comprehensively investigated in the present study. The results showed that a larger number of antibiotics could be detected quantitatively in wild samples, while the farmed samples had higher concentrations. Twenty, 17, and 14 target compounds were found in the muscles of wild molluscs, wild fish and farmed fish with total concentrations of 2.02–16.4 ng g–1, 0.51–11.9 ng g–1, and
