Abstract
The present study constitued sixty cattle, two months to four years oldof both sexes. This study was take place between December 2000 to December2001 and it was performed on 50 animals, which are kept in area near (1-2 Kilometer) northerly to sugarcane factory found in Deshna city belonging to Quena Governorate.These animals are sub-divided into three separate groups (group I,II& III) as shown in table 8.
Clinically healthy 10 animals (groupIV),which are kept away (30 Kilometers), south to the same factory,were used as control group. All animals under investigation were examined clincally in the field and in the abattior before slaughtering.
Estimation of lead levels in whole blood,feces,hair,livertissue and Kidney tissue in both lead-exposed cattle group(I) and non-lead exposed, (30 Kilometer away from the sugercane factory), clinically healthy group(IV) revealed higher lead content in whole blood samples than in fecal and hair samples, and higher lead content in Kidney tissue than liver tissue. Moreover there was signficant (P< 0.05) difference between lead content in both examined cattle groups in case of whole blood samples.While there was no significant difference in case of fecal,hair,liver tissue and kidney tissue samples.
