This Study performed to investigate the effects of Chlorpyrifos (one of the most used insecticides) on blood pictures of rats.

Thus a total of 110 male rats were used and experiment ally divided into four groups: the first group was used as control group .While the second group of rats received an oral daily doses of 1/10 LD₅₀. The third and fourth groups of rats were administered single oral dose of 1/10 LD₅₀ and 1/30 LD₅₀ respectively .The median lethal dose was determined which appeared to be equal to 81.2 mg/ kg. B. W.

Haematological investigations revealed an increase in white blood cell’s count (WBC), red blood cell’s count (RBC), and mean carpuscular volume (MCV). On the other hand there is a decrase in haemoglobin estimation (Hb), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC)and the total blood platelets count (PLT).
