Acute toxicity caused by deltamethrin to Unio elongatulus eucirrus is determined. It is observed that its toxicity on freshwater mussel increases with increasing concentration and exposure time. There are differences in the acute toxicity of deltamethrin for various fish species. The toxic effect changes with respect to species and size of fish and the duration of exposure. The results show that toxicity of deltamethrin for freshwater mussel under such conditions is also time-dependent. Although the sensitivity of the freshwater mussel is less than that of the fish, the results show that the insecticide deltamethrin has a harmful effect for mussels. It is suggested that deltamethrin shall be used with caution in agriculture to protect natural waters from contamination.
