BDE-47对4种海洋微藻抗氧化酶活性的影响
Effects of BDE-47 on the antioxidase activities of four species of marine microalgae
摘要
Abstract
The toxic effects of 2,2',4,4'-tetrabrominated biphenyl ether (BDE-47) at various concentrations on the activities of anti-oxidases in four species of marine microalgae (Chlorella autotropica, Chaetoceros muelleri, Heterosigam akashiwo and Skeletonema costatum) were examined through experimental ecology and biochemica1 methods. The results indicated that both SOD and CAT activities in the four species were enhanced in various degree to alleviate the oxidative damage from BDE-47 in the concentration range of 0.1~2.5μg·L~(-1). Compared with Heterosigam akashiwo and Skeletonema costatum, Chlorella autotropica and Chaetoceros muelleri were more sensitive to BDE-47 concerning SOD and CAT activities. The sensitivity of the four marine microalgae species to BDE-47 was in the order of Chlorella autotropica > Chaetoceros muelleri > Skeletonema costatum > Heterosigam akashiwo. Therefore, SOD and CAT in Chlorella autotropica could be used as the biomarkers to indicate pollution level of BDE-47 in marine environment.关键词
