Pollution by Veterinary Antibiotics in Urban and Rural Groundwater of Jiaxing
Pollution status by ten commonly used veterinary antibiotics, including three tetracyclines, three quinolones, two macrolides and two sulfonamides, were investigated in both rural rivers and urban rivets in Jiaxing city, an important pig breeding base in the Yangtze River Delta region of China.Results revealed the total concentration of the ten antibiotics in urban rivers ranged from 20.1 ng/L.to 61.2 ng/L.The highest proportion was taken by tetracyclines, accounting for 95%, with an concentration up to 44.0 ng/L.Quinolones shared the second largest proportion, about 29%, with a total concentration was up to 21.6 ng/L.Concentrations of sulfonamides and macrolides were low, respectively below 2.7 ng/L.and 63 ng/L.Antibiotics concentrations in rural rivers were morn serious than in urban rivers.The highest total concentration of the ten antibiotics in rural rivers was up to 467 ng/L, 60% of which was shared by tetracyetines, with the highest concentration being of 253 ng/L.Sulfonamides shared 20% of the total concentration with the highest concentration of 165 ng/L.The highest concentration of macrolides and quinoiones was 14.6 ng/L and 14.5 ng/L,respectively.
