Abstract

Ibuprofen as a non-steroidal anti-inflammatory drug can be detected in the aquatic environments all over the world. This study evaluated the effects of ibuprofen on the immune parameters of juvenile grass carp at the concentration in real environments which were determined by detecting its concentrations in the surface water of local rivers. The concentration of ibuprofen ranged from 13.2 to 95.5 ng/L with a mean value of 47.9 ng/L in the surface water of local rivers detected by solid-phase extraction followed by LC-MS/MS analysis. Accordingly, juvenile grass carp were exposed to 4.8, 48.0 and 480.0 ng/L of ibuprofen for 14 days. The serum lysozyme activity of these fish decreased, while the serum creatinine levels were not affected after the exposure. Moreover, the mRNA expression of interleukin 6 in the skin and interleukin 1 beta and tumor necrosis factor alpha in the gills was enhanced by this exposure. These results collectively suggest that ibuprofen at environmentally relevant concentration can affect the immune parameters of juvenile grass carp, providing an insight into the possibility of this contaminant to modify the immunostatus of fish.
