【摘要】：為評估太湖貢湖灣水域抗生素污染程度與生態(tài)風(fēng)險,利用高效液相色譜-串聯(lián)質(zhì)譜檢測分析了4類抗生素(四環(huán)素類、喹諾酮類、磺胺類、大環(huán)內(nèi)酯類)在貢湖灣表層水的污染特征.結(jié)果表明,16種目標(biāo)抗生素中,有13種在貢湖灣水體中檢出,質(zhì)量濃度范圍為0.005~4.720μg·L-1,其中土霉素(oxytetracycline,OTC)檢出濃度最高.抗生素在南北兩湖灣的檢出水平也互有高低,其中四環(huán)素類抗生素北部灣要高于南部灣,而喹諾酮類和磺胺類抗生素的檢出量南部灣要高于北部灣.采用風(fēng)險商值法進(jìn)行風(fēng)險評估,初步評估結(jié)果為貢湖灣水域中檢出的抗生素中,處于高風(fēng)險的有5種:四環(huán)素類土霉素(OTC)及喹諾酮類諾氟沙星(norfloxacin,NOR)、氧氟沙星(ofloxacin,OFL)、環(huán)丙沙星(ciprofloxacin,CIP)和恩諾沙星(enrofloxacin,ENR),占檢出種類38.5%;中風(fēng)險有4種:四環(huán)素(tetracycline,TC)、金霉素(chlortetracycline,CTC)、羅紅霉素(roxithromycin,ROX)和磺胺甲基異VA唑(sulfamethoxazole,SMX),占檢出種類30.8%;其余4種磺胺甲基嘧啶(sulfamerazine,SMR)、磺胺甲氧噠嗪(sulfamethoxypyridazine,SMP)、磺胺喹VA啉(sulfaquinoxaline,SQX)和甲氧芐氨嘧啶(trimethoprim,TMP)為低風(fēng)險.評估結(jié)果表明貢湖水域抗生素存在一定生態(tài)風(fēng)險,其中四環(huán)素類和喹諾酮類尤為突出,應(yīng)引起足夠的注意,并采取相應(yīng)防范措施.
[Abstract]:In order to assess the extent of antibiotic contamination and ecological risk in the waters of Gonghu Bay, Taihu Lake, four kinds of antibiotics (tetracycline, quinolones, sulfanilamide) were analyzed by high performance liquid chromatography-tandem mass spectrometry (HPLC / MS). The pollution characteristics of macrolides in the surface water of Gonghu Bay. The results showed that 13 of the 16 target antibiotics were detected in the waters of Gonghu Bay. The concentration range was 0.005 ~ 4.720 渭 g / L ~ (-1), and oxytetracycline OTCwas the highest. The detection level of antibiotics was higher in the Beibu Bay than in the Southern Bay, and the detection of quinolones and sulfanilamides in the Southern Bay was higher than that in the Beibu Bay. Risk quotient method was used to evaluate the risk. The preliminary results were among the antibiotics detected in the waters of Gonghu Bay. Five species are at high risk: tetracycline oxytetracycline (OTC) and quinolone norfloxacinine (NORO), ofloxacinOFLL, ciprofloxinCIPs and enrofloxacinen enrofloxin ENRRN (38.5 per cent of the tested species); and four types of risk: tetracycline, chlortetracycline, CTCX, roxithromycin (roxithromycin) The other four sulfamerazine SMRs, sulfamoxypyridazineine SMPP, sulfamoxaline sulfaquinoxaline SQXX and trimethoprimidine trimethoprimium (TMPP) were found to be at low risk in addition to sulfamethoxypyridazoleine sulfamethoxypyridazine (SMPP), sulfaquinoxaline (SQX) and trimethoprimium (TMPP) for the other four sulfamethoxazolium sulfamethoxypyridazine (SMPP) and sulfamethoxaline (SMPX). The results showed that antibiotics in the waters of Gonghu Lake had some ecological risks, especially tetracyclines and quinolones, which should be paid enough attention to, and the corresponding preventive measures should be taken.
