Acute Toxity Of Diazin Of Rotifers, Cyclops, Mosquito Larvae And Fish
Acute toxicity tests were conducted in renewable static bioassays to determine the 48h-lc50 of Diazinon on rotifers, cyclops, mosquito larvae and fish. The 48h-lc50 values were 3.93 mg/l, 39.39,9.87 and 189.31μg/l for rotifers, cyclops, mosquito larvae and fish respectively. The rotifers had the hig...

| description | Acute toxicity tests were conducted in renewable static bioassays to determine the 48h-lc50 of Diazinon on rotifers, cyclops, mosquito larvae and fish. The 48h-lc50 values were 3.93 mg/l, 39.39,9.87 and 189.31μg/l for rotifers, cyclops, mosquito larvae and fish respectively. The rotifers had the highest value hence the least sensitive to Diazinon intoxication. The probit mortalities of the test organisms was found to be positively correlated to the log-concentration except for rotifers, which showed negative correlation at 5% level of significance. Diazinon was highly toxic to mosquito larvae and cyclops, which are targets in the control of vectors of parasitic disaeses. The toxicity of Diazinon on aquatic fauna thus affects the trophic levels in aquatic biota and the productivity of water bodies.
