Abstract
SUMMARY
The goal of the present investigation was to establish the role of hair as a reliable indicator for determination of some metallic pollutants (lead, cadmium and mercury) in tissues of the exposed animals. Thus, metals levels in hair can serve as early warning tool.
A total number of 50 male cattle (l.9-4 years old) and 50 male buffaloes (1.9-3 years old) were subjected to study. These animals were slaughtered in slaughterhouses belong to Assiut govemorate (El-Wasta, Assiut and Mosha). Animals were examined clinically before slaughtering for presence of any abnonnal clinical signs and for detection of any apparent toxic manifestations. Blood, hair, liver, kidney, muscle and bone samples were collected from each animal under investigation. All samples were packed in clean, labeled plastic bags and then kept in deep freeze (-20 C) for chemical analysis. Digested samples of whole blood, hair, liver, kidney, muscle and bone were preceded for determination of lead, cadmium and mercury concentration using ion analyzer EA 920, Orion research, Orion American Company. pH of samples were adjusted to 4-7 before analysis.
Results can be summarized as follow:
1. Lead
A. Concentration of lead in examined tissues
Cattle (1.9-4 years old) showed lead concentration values (X ± SE) of
0.342 ± 0.055, 0.039 ± 0.003, 0.211 ± 0.033, 0.220 ± 0.015, 0.11 ± 0.013 and 0.178 ±
0.016 ppm in hair, blood, liver, kidney, muscle and bone respectively. While, in buffaloes (1.9-3 years old) were 0.147 ± 0.018, 0.023 ± 0.0032, 0.061 ± 0.011,
0.131 ± 0.014, 0.032 ± 0.0026 and 0.072 ± 0.010 ppm in hair, blood, liver, kidney, muscle and bone respectively,
