Toxicity of copper to tropical freshwater snail (Pila ovata)
Keywords:
Copper toxicity, freshwater snail, median lethal concentration, median lethal time
Abstract
The potential toxicity of copper to freshwater snail (Pila ovata) was investigated in a static renewal bioassay for 96 hours. Chemically pure salts of copper sulphate (CuSO4. 5H2O) dissolved in distilled water was used as toxicant. Five copper ion concentrations with a control group were prepared. The LC50 at 24 h, 48 h, 72 h and 96 h was 4.67, 2.12, 1.64 and 0.59 mg/l respectively. The LT50 of copper concentrations of 0.05 mg/l, 0.1 mg/l, 0.5 mg/l, 1.0 mg/l and 2.0 mg/l were 123.86 h, 97.20 h, 83.33 h, 75.32 h and 60.04 h respectively. No death was recorded in the controls. Survival time decreased with increasing concentrations of copper ion. The results showed that copper is toxic to Pila ovata and could pose serious threat to their survival in natural environment
