Despite the lower rate of exposure to leaded compounds in the past ten years, due to reducedlead petrol concentrations in the ambient air and improvement in environmental control measures, leadpoisoning is still an occupational and environmental disease of great concern in public health. Thepresence of other sources of lead exposure after the ban of leaded gasoline could be a risk factor forelevated blood lead concentrations. In this study blood lead levels (BLL) were screened in bothoccupationally and non-occupationally exposed groups in the Palestinian Territories by inductive coupledplasma-mass spectrometry (Agilent 7500 ICP-MS). The non-occupationally exposed groups included 18normal healthy smoker males, 18 non smoker males, and 18 females. Occupationally exposed groupsinclude 25 workers in the assaying and refining of gold and 19 workers in auto-repair garages. Data wasanalyzed using the statistical computer package (SPSS). Mean blood lead levels of all groups were belowthe action level according to Centers for Disease Control (CDC) and Occupational Safety and HealthAdministration (OSHA) (
