江苏省畜禽养殖场水环境中四环类抗生素污染研究

Pollution of Tetracyclines from Livestock and Poultry Farms in Aquatic Environment in Jiangsu Province,China

2009年在江苏省范围内采集27个规模化养殖场排水口和周围环境水体样品53个,用高效液相色谱-三重四极杆质谱对其中的土霉素(OTC)、金霉素(CTC)、四环素(TC)和强力霉素(DOX)等四环素类抗生素污染进行了检测。结果显示,土霉素、金霉素、四环素和强力霉素在水体样品中的检出率分别为60.4%、60.4%、34.0%和17.0%,污染量分别在0.07～72.91、0.10～10.34、0.08～3.67μg·L-1和0.11～39.54μg·L-1之间,检出率以土霉素和四环素最高;猪养殖场中土霉素、四环素和强力霉素的污染量比牛和鸡场的要高,牛场中金霉素和强力霉素的污染量明显低于鸡场;从区域上看,苏南地区受到的污染明显高于苏北。

Total 53 samples of outlets and surrounding water environment were collected from animal farms in Jiangsu Province in 2009,the pollution of oxytetracycline（OTC）,tetracycline（TC）,chlortetracycline（CTC）and doxycycline（DOX）were determined by LC-MS.Results revealed that the incidence of detection were 60.4%,60.4%,34.0% and 17.0%,the polluting amount was 0.07～72.91,0.10～10.34,0.08～3.67 μg·L-1 and 0.11～39.54 μg·L-1 for OTC,CTC,TC and DOX respectively.OTC and TC had the highest incidence of detection.Among the different animal farms,the pollution amount of OTC,TC and DOX in the pig farms was higher than in dairy and chook farms,while the pollution amount of CTC and DOX in dairy farms was obviously less than chook farms.The pollution of the southern areas of Jiangsu was obviously higher than the north of Jiangsu.
