The study was conducted on 240 random samples (80 for each of muscle, liver and  kidney), which were collected from 80 carcasses (40 male sheep and 40 calves) from Homs Governorate including Palmyra region because it is considered rural region far away from contamination resources. For detection contamination by lead samples were tested using atomic  absorbation technique and the results showed a proportional increasl of lead concentration in liver, kidney, and muscles respectively. Contaminated level was higher in calves comparing to male sheep, this means the proportion was greater than the critical limit according to Syrian standard measures. The average of values in liver ,kidney and muscle of calves were 1.4040,1.6397and 1.9010mg/kg respectively and in male sheep were 1.5613,1.1127 and 1.3747 mg/kg respectively. The mean concentration in Palmyra samples in liver, kidney and muscle of calves were 0.319-0.346 and 0.385mg/kg and in sheep male were0.243-0.277and 0.31mg/kg. Muscle samples in Palmyra region only were greater than the permissible limit while liver and kidney were within the permissible limit
