Abstract:

The aim of this analysis was to look into the levels of heavy metals (lead and cadmium) in tap water, well water, and dairy cattle blood in the Baghdad province (Taji, Abu Ghraib, and Youssoufia) regions. Methods: Measuring certain blood and biochemical parameters; Red Blood Cells, White Blood Cells, hemoglobin, differential white blood cells count, total cholesterol, albumin, globulin, liver enzymes, aspartate aminotransferase, and alanine aminotransferase activity are among the parameters. Results: Lead concentration in the tab and well water of the Youssoufia region was significantly higher (P≤0.05) than Taji and Abu Ghraib. The Cadmium concentration of the tab water in the different regions shows a non-significant difference between the different regions. The lead and cadmium concentrations, WBCs, differential WBCs count in dairy cattle blood were recorded significant (P≤0.05) increase in the cows of Youssoufia compared with other regions, a significant decrease (P< 0.05) in the RBCs count of dairy cattle in Youssoufia and Taji, Hb were recorded significantly higher value (p < 0.05) in the dairy cattle of Abu Ghraib, total protein, albumin, globulin concentration, lymphocyte, neutrophils, basophils, showed non-significant (p > 0.05) differences among the different regions, liver enzyme AST and ALT concentration showed a significant increase (p < 0.05) in the serum of dairy cows in Youssoufia regions than other regions. Conclusion: The results showed there was a significant correlation coefficient between lead in drinking water and the blood of dairy cattle, while there was no significant relationship between cadmium and lead in drinking water and blood.
