摘要
在实验条件下采用生态毒理学和生物化学方法,选用常见的环境污染物多环芳烃蒽(Anthracene),以太平洋牡蛎(Crassostrea gigas)为实验材料进行毒理实验。研究了太平洋牡蛎D型幼虫、壳顶幼虫、幼贝和成贝4个不同发育时期中的3种抗氧化酶:超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)对蒽胁迫的敏感性。结果表明,在蒽胁迫下,D型幼虫和壳顶幼虫期3种抗氧化酶敏感性均为:POD>SOD>CTA;在幼贝和成贝期,其敏感性为:SOD>CTA,而POD表现出不稳定性。
The toxicological effect of environmental pollutant-polycyclic aromatic hydrocarbon-anthracene on Pacific Crassostrea gigas was examined using the methods of ecootoxicology and biochemistry. The sensitivity of three kinds of antioxidant enzymes:SOD, POD and CAT to anthracene at four different developmental phases was examined. The results showed that the sensitivity of three kinds of antioxidant enzymes to anthracene in D-type larva and numbone larva was POD 〉 SOD 〉 CAT, while in larvae and adult C. giga, the sensitivity order was changed to SOD 〉 CAT, with unstable POD's sensitivity.
