Abstract

The purposes of this study were to investigate the acute toxicity and effects of sublethal antimony (sb) concentrations on respiratory activity changes in the common carp (Cyprinus carpio). Median lethal concentrations were determined in acute tests. The 96-h LC50 value was 14.05 (11.09~17.80) mg L(-1). Common carp were exposed to 4 different sublethal levels of antimony (1.0, 2.0, 4.0, and 8.0 mg L(-1)) over a 28-day test period and a 14-day recovery period. On days 14 and 28, decreases in oxygen consumption were significant (p < 0.05) for the higher-exposure level groups (4.0 and 8.0 mg L(-1)). An increase in oxygen consumption was observed in the recovery period (on day 42) compared to the respective groups at the same level on day 28 at the higher exposure levels.

摘要

本研究的目的是调查锑（Sb）的急性毒性以及亚致死浓度对鲤鱼（Cyprinus carpio）呼吸活动变化的影响。在急性试验中测定了半数致死浓度。96小时半数致死浓度（LC50）值为14.05（11.09~17.80）mg L(-1)。在为期28天的试验期和14天的恢复期内，将鲤鱼暴露于4种不同亚致死水平的锑（1.0、2.0、4.0和8.0 mg L(-1)）中。在第14天和第28天，较高暴露水平组（4.0和8.0 mg L(-1)）的耗氧量显著下降（p < 0.05）。与较高暴露水平下第28天的相应组相比，在恢复期（第42天）观察到耗氧量增加。
