Abstract
In this paper, the occurrence and removal of eight fluoroquinolone antibiotics were investigated at a sewage treatment plant (STP) in Shanghai, China. The most frequently detected fluoroquinolone antibiotics in the present study were norfloxacin, ciprofloxacin and lomefloxacin. The concentrations of these compounds in water samples at the STP ranged from 103 to 1786 ng L
-1
, 14 to 1406 ng L
-1
and 21 to 2246 ng L
-1
, respectively. The other fluoroquinolone antibiotics were detected only in a few samples from the STP. FQs in aquatic phase could not be eliminated completely from the STP, with the removal efficiencies from 70% to 100%. The concentrations of FQs in water detected in summer were higher than in other seasons, due to the more desorption from sludge to aquatic phase under higher temperature.
本文对上海某污水处理厂8种氟喹诺酮类抗生素的发生及去除情况进行了调查。本研究中检出最多的氟喹诺酮类抗生素为诺氟沙星、环丙沙星和洛美沙星。这些化合物在STP水样中的浓度分别为103 ~ 1786 ng L -1、14 ~ 1406 ng L -1和21 ~ 2246 ng L -1。其他氟喹诺酮类抗生素仅在STP的少数样品中检测到。STP不能完全去除水中的FQs，去除率在70% ~ 100%之间。夏季水体中FQs浓度高于其他季节，这是由于温度越高，污泥向水相的解吸越多。
