| Abstract: | To study the toxic effects of benzob]fluoranthene on the aquatic life,the activities of antioxidant enzymes(CAT,SOD,GPx) and MDA content in visceral masses of green-lipped mussel(Perna viridis) were measured during 15 days exposure to benzob]fluoranthene with the concentration of 2.0,10.0 and 50.0 μg·L-1.After benzob]fluoranthene exposure,the green-lipped mussels were then transferred to clean seawater to be cultivated for 10 days,and the above four parameters were also analyzed during this period.The results showed that,in 2.0 μg·L-1 treatment group the CAT activity was induced and then inhibited,and its activity reached the peak value after 4 days exposure,with induction rate being 81.9%;in 10.0 and 50.0 μg·L-1 treatment groups the SOD activities were first inhibited,then induced,and again inhibited,and after 2 days exposure the inhibition rates were 31.9% and 49.8%,respectively,while after 8 days exposure the induction rates were 24.9% and 62.3% respectively;in 10.0 and 50.0 μg·L-1 treatment groups GPx activities were inhibited,and then induced,and after 8 days exposure the inhibition rates were 30.6% and 40.6%,respectively,while after 15 days exposure the induction rates were 20.6% and 21.3%,respectively.After being transferred to the clean seawater,the activities of antioxidant enzymes in 2.0 and 10.0 μg·L-1 treatment groups gradually restored to the control levels,but the activities of SOD and GPx in 50.0 μg·L-1 treatment group were still below the control level after 10 days.In this study,it is found that in certain range of concentration and time,the damage to Perna viridis induced by benzob]fluoranthene could be reflected by the changes in the activities of SOD,CAT and GPx.Benzob]fluoranthene and MDA content showed significant dose-effect and time-effect relationships,which indicated that benzob]fluoranthene exerted toxic effects on Perna viridis by way of oxidative damage. |
