摘要：

采用固相萃取、液相色谱/串联质谱法(LC-MS/MS)分析香港维多利亚港(维港)与珠江广州河段水体中9种典型抗生素药物含量.结果表明,在维港海水中,只检出较低含量的氟喹诺酮和大环内酯类抗生素;无论是在枯季(3月)还是洪季(6月),珠江广州河段河水中各种抗生素(阿莫西林除外)均可检出,而且含量较高(分别在70489 ng.L-1和1369 ng.L-1之间),其含量水平明显高于美、欧等国河流中相应污染物的含量,其中红霉素、磺胺嘧啶等与国外污水处理厂所检出的含量水平相当.数据也表明,河水中抗生素含量水平受季节和水量变化的影响很大,枯季河水中抗生素含量明显高于洪季.与枯季相比,洪季河水中药物含量具有明显的日变化.
