The synthetic pyrethroid of type II with cyanogroup Deltamethrin induced changes in the blood of the fish Ctenopharyngodon idellathat was detected by a simple preliminary experiment as Micronucleus (MNT). The fish are exposed to both lethal and sublethal concentration of 96 hrs (1/10th of LC50) of technical grade and 11% EC Decis Only the fish exposed to lethal concentrations of the technical grade changes in the nucleus whereas in the sublethal concentrations of technical grade and lethal and sublethal concentrations of 11% EC Decis have not resulted any changes. This will pave the way of Carcinogenicity.
