| 利用固相萃取-高效液相质谱-串联质谱（HPLC-MS/MS）技术，调查了福建厦门市和莆田市畜禽养殖场的畜禽粪便、粪肥、作物土壤、沟渠底泥和人工湿地土壤共27份样品中8种抗生素的污染特征。结果表明：从样品类型来分析，除了大环内酯类在畜禽粪便中的平均检出浓度大于有机肥之外，样品中抗生素浓度顺序为有机肥>畜禽粪便>作物土壤、沟渠底泥和人工湿地；从抗生素种类来分析，喹诺酮类抗生素（QNs）的检出浓度最高，单个样品总含量∑QNs在粪肥中最高达到2 967.6 μg·kg-1，在作物土壤中最高达到579.0 μg·kg-1；值得注意的是，14份作物土壤样品中有50%样品的∑QNs超过生态毒性效应浓度（100 μg·kg-1）；磺胺类抗生素（SAs）和大环内酯类抗生素（MLs）的检出浓度相对较低，单个作物土壤样品∑SAs和∑MLs都低于100 μg·kg-1；从检出平均值和检出率来分析，磺胺类污染以磺胺二甲嘧啶（SM2）为主，大环内酯类以罗红霉素（ROX）为主，喹诺酮类检测浓度环丙沙星（CIP）最高，检出率恩诺沙星（ENR）最高。畜禽养殖基地的抗生素污染问题应该引起重视。 |
| 英文摘要: |
| Five kinds of samples, including animal feces, manures, arable soils, ditch sediments and surface soils of constructed wetlands, were collected from three livestock and poultry feedlots in Fujian Province. Eight antibiotics in these samples were investigated using liquid chromatography-electrospray ionization tandem mass spectrometry（HPLC-MS/MS）. The concentrations of all antibiotics in manure and animal feces were totally higher than those in other three kinds of samples. The concentration of quinolones（∑QNs） and sulfonamides（∑SAs） in manure were higher than those in animal feces, whereas the results for macrolides（∑MLs） were opposite. The concentrations of quinolones were observed higher than those of sulfonamides and macrolides in all the samples, with a range of |
