Abstract:- This study was designed to determine the levels of two toxic elements (lead and cadmium) in kidney,
liver and the muscles of camels and sheep. The samples of slaughtered animals were collected from
different western regions (Zawia, Sorman and Egilate) in Libya. The Atomic Absorption
spectrophoto-meter was used to carry out the measurements of heavy metals of samples. A
recognized highly significant effects (P≤ 0.01) of species; Parts of body, region and interaction
among them on residual of lead and cadmium in kidney, liver and muscle were measured. The
concentration of lead and cadmium were 107.42 and 53.0 g/kg in camels, which higher than values
measured for sheep (75.32 and 17 g/kg). The concentration of lead and cadmium were 143.33 and
50 g/kg; 93.66 and 45 g/kg and 53.16 and 28 g/kg in kidney, liver and muscle, respectively.
Regarding the effect of region, the concentration of lead and cadmium were 118.62 and 48 g/kg;
81.25 and 41g/kg and 90.29 and 34 g/kg for Zawia, Sorman and Egilate regions, respectively. The
reference values of lead and cadmium concentration in kidney and liver reported by Egyptian
Organization for Standardization (EOS) and FAO are 0.5 mg/kg (500g/kg) and 0.1 mg/kg
(100g/kg), respectively. Thus, the mean concentrations of lead and cadmium in kidney, liver and
muscle of slaughtered camels and sheep in this study were safe and lower than permissible limit
recommended. Information about levels of these metals is very important to the consumers because
they are awareness concern with healthy food especially meat.
