Title

DETERMINATION THE LETHAL CONCENTRATION (LC50 96 H) OF CHLOROPYRIFOS AND DIAZINON ON (RUTILUS RUTILUS CASPICUS)

Pages

  73-78

Abstract

 The survey acute toxicity of CHLOROPYRIFOS and DIAZINON toxins that use large quantity in agriculture fields specific in Golestan province studied on RUTILUS RUTILUS CASPICUS fingerlings (1-3g) in this research, aim to determine the 50% lethal concentration (LC50) in 96 hours. These experiments carried out in static condition and based on TRC, 1984 standard method in 4 days, and controlled of the effective water physico - chemical factors that having ranges pH =7-8.2, DH=205 mg /l (CaCO3), DO=7mg/l and Temp=26±oC .During experiments reaction and behaviour of the fingerlings exposure of toxin seen carefully. Early experiments for find of mortality range with released in to a 20lit aquarium (10 fingerling of 1-3g in aquvarium) and continous aeration. Finally experiments with 5 treatments, 3 repetitions and 1 blank. On the base of obtained results by Probit program version 1.5 LC50 value of CHLOROPYRIFOS and DIAZINON in 96 hours were 0.016 and 12.81 mg/l on RUTILUS RUTILUS CASPICUS respectively, and also Mac (Maximum allowable concentration) value of this toxins were determined 0.0016 and 1.281 mg/l for RUTILUS RUTILUS CASPICUS respectively.
