Trace metals in biological samples namely hair , blood and urine were examined in roadways cleaners workers exposed to Pb. Hg, Ni, Cuand Crmetals and in controls group.The significant levels exposed and unexposed subjects in hair , blood ,and urine have been computed by student test at p<0.05 statistical analysis data showed through the connection relation ship between the two groups (test and control ) ,element (Ni, Cu, Hg) non- significant , except (Cr, Pb)significant for the models hair. The serum samples showed a statistical analysis data asignificantrelation ship for (Cr, Pb, Ni), except (Cu, Hg) non- significant models urine sample the statistical analysis data showed asignificant relation ship (Cr, Hg, Cu, Ni)and non- significant for the lead .The behavior has been explained in context to the type of exposure and the periods of exposure for each element .
This study has shown that among cleaner workers ,the blood lead level below thane WHO permissible exposure limite(40 mg/dl for men)
