Also, to estimate the concentration of previous metals and the effects of breed and regions and interaction between them in camel and sheep milk. One hundred and eight and Fifthy four samples consisting of muscle, liver and kidney body of parts and thirty six and eighteen samples of milk from both species were collected from camel and sheep from market in different regions in Western Libya. The Atomic Absorption spectrophotometer (Thermo Electron Corporation, Germany) used to carry out the measurements of heavy metals of samples. A highly significant effect at level 1% ( p≤ 0.01) for the previous factors on lead concentration in meat was observed. The concentration of lead in camel was 107.42 higher than 75.32 in sheep meat (mutton). The effects of for interaction among Species, Region and body of parts factors on lead concentration in meat were highly significant at level 1% ( p≤ 0.01). A highly significant effect at level 1% ( p≤ 0.01) for the effects of species; region and interaction between species and region on residual of lead in milk was observed. A highly significant effect at level 1% ( p≤ 0.01) for the previous factors on cadmium concentration in meat was observed. The concentration of cadmium in camel was 0.053 higher than 0.017 in sheep meat (mutton). Concern the effect of region, the highest value 2 was 0.048 in Zawia followed by value 0.041 in Sorman and the last value was 0.034 in Alagelat region. Regarding the effect of body of parts on cadmium concentration , the highest value was 0.050 in kidney followed by value 0.045 in liver and the last value was 0.028 in Muscle. The effects of Species, Region and body of parts interaction on cadmium concentration were highly significant at level 1% ( p≤ 0.01). Concern the effect of species on the body of parts of body, the concentration of cadmium in kidney were 0.065 and 0.015, followed by the values in liver of 0.058 and 0.019 and the last values were in muscle of 0.035 and 0.013 for camel and sheep species, respectively. A highly significant effect at level 1% ( p≤ 0.01) for the effects of species; region and interaction between them on residual of cadmium in milk was observed. The concentration of lead in she camel milk was 0.009 higher than value of 0.005 in ewes milk. Concern the effect of region, the highest value was 0.081 in Zawia followed by value 0.076 in Sorman and the last value was 0.075 in Alagelat region.This study was designed to examine the effects of different Western regions in Libya, body of parts of body (liver, kidney and muscle) and interaction between them on Pb and Cd concentration in camel and sheep meat.
