Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Zoology Summary: The present investigation was conducted to compare between the ecotoxocological effects of Ca, Mg, Fe, Cu, Zn, Co, Mo, Mn, B, Al, Sr, Pb, Ni, Cd and Cr on the saw-scaled viper, Echis pyramidum and the Kenyan sand boa, Eryx colubrinus inhabiting Gabal El-Nagar and Kahk Qibliyyah respectively in El-Faiyum desert, Egypt. Accumulation varied significantly among the liver, kidney and muscle. The relationship between concentrations of heavy metals in snakes and those in the soil from the collected sites was established by analyzing metal DPTA in soil. Bioaccumulation factor is calculated to estimate the degree of toxicity within the tissues. Morphometric analysis was recorded. With the exception of interorbital width, all body morphometric measurements were higher in E. p. than in E. c. Body, liver, gonad, kidney and heart weight, HSI, GSI, RBCs count, Hb content, PCV, MCV, MCH, MCHC, plasma glucose, total lipids and total proteins, total proteins in muscle and liver and total lipids in muscle showed a significant increase in E. p. except, total lipids in liver. Discontinuous polyacrylamide gel electrophoreses for LDH and Ü-EST were conducted for biochemical differentiation between E. p. and E. c. Three Ldh isoforms were recorded in both species and the activity and RF of Ldh-1 seemed to be higher in E. p. than in E. c. Ü-Est showed five isozymic forms fractions in E. p., while it showed only four isoforms in E. c. Ü-Est-1 was the first clear, dense and thick isoform in E. p., but it was completely absent in E. c.. Histopathological examination showed damage and alterations of liver, kidney and testes sections. The tissues of E. c. were more destructed than those of E. p.
