Some trace metals have no biological role, are toxic when in a certain form andconcentration. The aim of the present study is to study the effects of exposure to thevapors of crude oil (vehicle fuel) on some trace elements value and kidney function testsin serum of crude oil station workers. The study includes (30) men crude oil stationworkers (group 1), and (30) men non crude oil station workers (group 2). The meanvalue of serum aluminum (Al), barium (Ba), zinc (Zn), manganese (Mn), iron (Fe), andvanadium (V) were significantly higher in (group 1) compared with (group 2) (p<0.05),while the mean value of serum silver (Ag) in group 2 was significantly higher than thatof group 1, while {mercury (Hg), and lead (Pb)} in group 1 no significantly higher thanthat of group2, the serum creatinine and uric acid in group 1 was significantly higherthan that of group 2, and serum urea in group 1 was non significantly higher than that ofgroup 2. Based on the findings of the present study, it can be concluded trace elementsin serum of crude oil station workers are abnormal and affect dramatically of kidneyfunctions.
