Effects of salinity and pH on acute toxicity of dimethoate to Puntius ticto



Effects of salinity and pH on acute toxicity of dimethoate to Puntius ticto



Uttar Pradesh Journal of Zoology 26(2): 143-148



Acute toxicity tests were carried out to estimate the LC50 values of dimethoate to the freshwater teleost, Puntius ticto. The LC50 values were obtained for 24, 48, 72 and 96 hr exposures are 6.839, 5.555, 5.070 and 5.012 ppm at normal laboratory conditions. Observations have been made whether the LC50 values were affected by the environmental factors i.e pH and salinity. These environmental factors play an important role in the toxicity of pesticides in fish.
