铜胁迫对铜锈环棱螺致死率、富集性、CAT和SOD的影响
Effect of Copper Stress on Lethal Rate, Cu Enrichment, CAT and SOD Activities of Bellamya aeruginosa
摘要
Abstract
Effects of coper on lethal rate and Cu enrichment of Bellamya aeruginosa and CAT and SOD activities in the hepatopancreas of Bellamya aeruginosa under Cu stress were studied. Bellamya aeruginosa was collected from a river in Chashan of Ouhai, Wenzhou City, Zhejiang Province. Results show that Bellamya aeruginosa was quite capable of tolerating low concentrations of Cu2+ (1. 0 and 2. 0 nig · L-1) , but showed a relatively high lethal rate when ρ ( Cu2 + ) was in the range from 4. 0 to 8. 0 mg · L-1. When ρ ( Cu2 + ) was 0. 2 - 0. 8 mg · L-1, Bellamya aeruginosa enhanced its Cu enrichment with its exposure to the toxicant getting longer and the toxicant higher in dosage. However, when ρ(Cu2+ ) reached 1.6 mg · L , its Cu enrichment declined with the duration of its exposure. Cu stress significantly affected CAT and SOD activities in the hepatopancreas of Bellamya aeruginosa.关键词
