摘要
2005—2006年在江苏省范围内采集了181个集约化养殖场畜禽排泄物样品,用高效液相色谱对其中的四环素类抗生素残留进行了检测。结果显示,土霉素(OTC)、金霉素(CTC)、美他环素(MC)、多西环素(DC)在排泄物样品中的检出率分别为16.6%、38.1%、18.8%、17.1%,残留量中位数分别在2.11、11.96、3.07、4.63mg·kg-1,均以金霉素最高;在不同动物的排泄物中,牛排泄物中金霉素的残留量比猪的要高,美他环素在鸡排泄物中的残留量较高;从区域上看,各区域之间药物残留量差异不显著。
181 samples of animal manure were collected from intensive farm in Jiangsu province from 2005 to 2006, the residues of oxytetra- cycline (OTC), chlortetracycline (CTC), methacycline (MC) and doxycycline (DC) were determined by HPLC. The results reveal that percent ages of detection are 16.6%, 38.1%, 18.8% and 17.1%, the average residues are 2.11, 11.96, 3.07 and 4.63 mg·kg^-1 for OTC , CTC, MC and DC respectively. CTC has the highest pollution load. In different kinds of animal manure, the residues of CTC in dairies are higher than in pigs, while the residues of MC were higher in chooks. The residues have no obvious difference among different areas.
