摘要
为探讨水产养殖中氟喹诺酮类药物残留对水生生物的毒性效应,研究了盐酸恩诺沙星对斜生栅藻(Scenedesmus obliquus)的急性毒性.结果表明,药物质量浓度为31.25,62.5,90,125,250μg/mL的各药物质量浓度组对斜生栅藻的生长均有抑制作用,并且随药物处理质量浓度的增大,藻细胞的生长逐渐降低,显示出明显的剂量效应关系.盐酸恩诺沙星对斜生栅藻的24,48,72,96h的EC50值分别为59.70,62.75,114.67,100.43μg/mL,叶绿素a和叶绿素b含量随着盐酸恩诺沙星处理质量浓度的增大呈现相同的变化趋势.
In order to study the toxic effects of fluoroquinolones residues on aquatic organisms, Scenedesmus obliquus was exposed to Enrofloxacin hydrochloride of five concentrations of 31.25, 62.5, 90, 125, and 250 μg/mL. The results showed that Enrofloxacin hydrochloride had inhibi- tion effects on the growth of S. obliquus and the inhibition increased correspondingly with the increase of concentrations. The EC50 values of 24, 48, 72 and 96 h of Enrofloxacin hydrochloride were 59.70, 62.75, 114.67 and 100.43 /,g/mL respectively. Enrofloxacin hydrochloride had the same effects on the contents of the chlorophyll-a and chlorophyll-b.
