The levels of total antioxidants, vitamin E and certain trace metals (Mg, Fe, Zn, Mn, Cu, Cr, Cd, Pb and Se) were determined in Nigerians who were occupationally exposed to chemicals for a period ranging from 16 to 20 years using colorimetric method and atomic absorption spectrophotometer respectively. In the automobile mechanics, the levels of chromium, cadmium and lead were significantly higher when compared with controls. In the motor painters, chromium and cadmium were significantly higher when compared with controls. Levels of manganese, copper, cadmium, lead and total antioxidants were significantly higher in panel beaters compared with controls. In the battery chargers, only total antioxidants were significantly higher compared with controls. The study shows that metal toxicity is imminent in panel beaters, automobile mechanics and motor painters and that the metals involved vary with occupations. This raises the need for public awareness about the hazards of different occupations in order to enable these professionals take necessary precautionary measures.
