| 英文摘要 | Cadmium (Cd) contamination is a severe problem in the Bohai Sea (China),especially in the estuarine and coastal environments with low salinity.In this study,adult oysters Crassostrea gigas were exposed to 4 doses of Cd (5,20,80 and 240 mug·L~(-1)) at either normal (31.4 psu) or low (15.7 psu) salinity for 7 days.The potential impact of low salinity on the toxicological effects of Cd was investigated by measuring the variations of Cd and essential elements and biomarkers.After exposure to Cd,Na and Mg contents in the gills were significantly increased,and a significant interaction between Cd and low salinity on the change of K contents was identified.The increases in enzymes related to oxidative stress and energy metabolism were observed after exposure to the combined Cd and low salinity.What is more,the Cd-induced toxicological effects were affected by low salinity,manifested by the significant interactive effects on the malondialdehyde (MDA) contents and isocitrate dehydrogenase (IDH) activities.Further integrated biomarker response (IBR) analysis showed that the adverse effect of Cd on oysters was exacerbated with the increase of exposure concentration.The combined effect of Cd and low salinity was much greater than that of single Cd exposure,indicating that low salinity aggravated the toxicological effects of Cd on oysters.Therefore,the impact of low salinity on the toxicity of environmental contaminants should be fully considered to comprehensively evaluate their environmental risks in the coastal zones. |
