BDE209胁迫对翡翠贻贝(Perna viridis)SOD、MDA和GSH的影响
Effects of BDE209 on the SOD, MDA, GSH of Perna viridis
摘要
Abstract
As a kind of persistent organic pollutanls( POPs), deca-bromodiphenyl ether( BDE209) belongs to polybrominated diphenyl ethers (PBDEs), which were produced in 1960 and used largely all around the world. Because of the characteristics of difficult degradation, bioac-cumulation and biological toxicity, BDK209 can cause the greater harm on the environment and organisms. Therefore, it is necessary to strengthen the research on the toxic effect and mechanism of BDE209 on the marine organisms. The semi-static experiments were carried out by setting 3 concentration groups(0.1, 1 mg·L-1 and 10 mg·L-1) of BDE209 to study the variation trends of the activity of superoxide dis-mutase(SOD) as well as the contents of malondialdehyde(MDA) and glutathione(GSH) in 2 tissues of the mantle and visceral mass of the green mussels (P. viridis) which were exposed to BDE209 for 1 d, 3 d, 7 d and 15 d, and then the recovery of these indexes were analyzed during the releasing period of 3 d and 7 d. The result showed that, during the exposing period, the activity of SOD in the 2 tissues was induced obviously at first, and followed by the significant inhibition( P<0.01) with the exposing time, and the content of MDA in the mantle varied repeatedly between the induction and the inhibition, while the content of MDA in the visceral mass was induced significantly with the highest induction rate reaching to 22.83% after 3 days of exposing. The content of GSH in the mantle of the green mussels (P. viridis) was induced significantly(P<0.01) in the early days, but later the induction effect declined gradually and turned to be inhibited significantly(P<0.05) after 15 days of exposing, and the content of GSH in the visceral mass was induced significantly (P<0.05), which decreased obviously with the increasing concentration of BDE209. During the releasing period, the contents of MDA and GSH in the 2 tissues of the green mussel (P. viridis )exposing to the 3 BDE209 groups were obviously higher than those of the control group(P<0.05),and the activity of SOD in the mantle was inhibited while in the visceral mass it was induced, except individual groups recovered to the normal level.关键词
