英文摘要	In the present study, the combined effects of seawater acidification and sulfamethoxazole (SMX) exposure on the antioxidant responses of Trochus niloticus were investigated using a fully factorial experiment. The topshells were exposed to three SMX concentrations(0 ng/L, 100 ng/L and 1 000 ng/L) at two pH levels(8.1 and 7.6) for 28 days. For individuals in each treatment, the enzymatic activities of superoxidase dismutase(SOD), catalase(CAT) and glutathione-S-transferase(GST), glutathione(GSH) contents and lipid peroxidation(LPO) levels were measured. It was found that all antioxidant enzyme activities and GSH contents were increased significantly in topshells under independent exposure of seawater acidification and SMX. Under the combination of seawater acidification and SMX exposure, antioxidant enzyme activities(SOD, CAT and GST) and GSH content were inhibited in gills of the topshells, while significant increase of lipid peroxidation levels was observed in the combined treatments. These results indicated that severe oxidative stress could be caused by short-term exposure to seawater acidification and SMX in T. niloticus, which indicated reduced fitness and viability caused by these two environmental stressors.
