SOME STUDIES ON HEMATOLOLOGICAL AND SOME BIOCHEMICAL CHANGES INDUCED BY HEAVY METAL IN CATTLE REARED IN BAHR FL- BAKAR RESIDUES IN MILK

摘要

Pollution of water has increased due to the industrial municipal waste and agricultural drainage. The aim of this work evaluate the haematobiochemical effect of heavy metal as well residues in milk in Bahar El Baker region in which Bahar El drainersea is considered the main place for agriculture drain, discharge, waste water and industrial effluents in Sharkia Governorate but the water in Fakous region from Nile River. Cattle reared in El Baker exhibited some clinical symptos represented by abdominal colic, liver dysfunction, renal damage, skeletal disorder symptoms resemble osteomalachia. A total of 50 random samples (20 each of each of raw cows milk, blood and 5 water samples collected from cattle in Fakous and Bahar El Baker City Governorate.Milk samples where placed in an ice box and immediately send to laboratory for determination of some heavy metals (lead, cadmium, mercury, copper and zinc) concentration by Atonal Absorpation Spectrophotometry. Blood samples were taken in two poration, first blood samples were collected in heparinized tube for total; erythrogram and total leukocytic and the second sampl^ was taken in centrifuge tube for obtain clear serum for biochemical analysis. The: analyzed data revealed that the meanvalues in the examined wafer samples collected from Fakous City amounted 0.90 ppm lead, 0.74 ppm cadmium, 0.092 ppm mercury, 1.07 ppm copper and 3.34 ppm zinc, Examined water samples collected from Bahar El Baker city conteand 2.89 ppm lead, 0.023 ppm cadmium 0.81 ppm mercury, 2.95 ppm copper and 4.72 ppm zinc. Also,the mean values of estimated element in the examined raw milk samples collected from Fakous City were 0.82 ppm lead, 0.33 ppm cadrmum,(0.074) ppm mercury, 0.19 ppm copper and 1.18 ppm zinc while respective values in examined raw milk samples collected from Bahar El Baker City were 1.90 ppm lead, 0.69ppm cadmium, 0.12 ppm mercury..0.036 ppm copper and 3.19 ppmzinc.The present work revealed that, erythrogram (total eryfhrocytic count, haemoglobin % and packed cell volume), total ieukocytic count, blood serum glucose, total proteins, albumin and globulins values allwere significantly decreased in cattle reared in Bahar El Bakar region with significant increase in serum levels of aminotra-nsferase (ALT- AST) alkaline phosphatase activity level, urea and creatinine levels. It could be concluded that, water in Bahar El Baker and milk "obtained from cattle reared in Bahar El Baker contain high concentrations of heany metals and induce adverse effect in hemato-biochemical Parameters s in lactating cows.
