摘要利用超声提取-固相萃取-高效液相色谱串联质谱法分析了青藏高原腹地申扎镇周边水土环境中磺胺类（SAs）、喹诺酮类（QNs）、大环内酯类（MLs）、四环素类（TCs）、β-内酰胺类（β-Ls）和氯霉素类（CPs）共6类34种抗生素的赋存特征.结果表明，申扎镇水体、沉积物和土壤中分别检出5、12和10种抗生素，浓度范围分别为0.01~11.27ng/L、0.96~56.38ng/g和0.01~41.04ng/g.水体中的主要抗生素为阿莫西林和磺胺氯哒嗪，土壤和沉积物中均以罗红霉素和诺氟沙星为主.牦牛粪便中检出8种抗生素，浓度范围为0.01~1.03ng/g.城镇和牧区抗生素的赋存特征具有显著差异，浓度水平呈城镇>牧区.生活污水排放和动物排泄分别是城镇和牧区抗生素的主要来源.与国内其它地区相比，申扎镇抗生素的赋存水平均较低，但申扎镇平均海拔>4700m，生态较脆弱，应该关注抗生素等新型污染物对高原生态环境的负面影响.

Abstract：The residues of 34 antibiotics including sulfonamides (SAs), quinolones (QNs), macrolides (MLs), tetracyclines (TCs), β-lactams (β-Ls) and chloramphenicols (CPs) were analyzed by ultrasonic extraction-SPE-HPLC-MS/MS in Shenzha Town of Tibet, located in the hinterland of the Qinghai-Tibet Plateau. The results showed that 5, 12 and 10 antibiotics were detected in water, sediments and soils of Shenzha Town, with the concentration ranges of 0.01~11.27ng/L、0.96~56.38ng/g and 0.01~41.04ng/g, respectively. In water, the dominant antibiotics were amoxicillin and sulfachloropyridazine, and in soils and sediments, roxithromycin and norfloxacin were dominant, 8 antibiotics were detected in yak feces at a concentration of 0.01~1.03ng/g. Between urban and pastoral areas, the significant differences were observed in the antibiotics distribution characteristics. The concentrations of selected antibiotics: urban areas > pastoral areas. In the urban areas, sewage discharges were the main sources of antibiotics while in pastoral areas, animal excretions were the essential source. The levels of antibiotics residues in Shenzha Town were lower than those residues in other regions in China. Because of the average altitudes of Shenzha town on the plateau environment are more than 4700m, the ecosystem is very fragile, and should pay more attention to the negative impacts of these antibiotics as new pollutants.

Key words： Tibet Shenzha Town antibiotics distribution characteristics
