Abstract
The aim of this study is to determine some metals in hair and serum samples of petrol station workers. A total of 50 petrol
station workers (exposure group) and 50 office workers (control group) were included in the study. Li, Ni, V, Tl, Ti and Sr
levels in hair samples and Sr, Ti and V levels in serum samples were measured using the ICP-OES instrument. Li, Ni, V, Tl, Ti
and Sr levels in hair samples were found to be significantly higher in the exposure group than in the control group. Ti level in
serum samples was found to be significantly higher in the exposure group than in the control group. However, Sr and V levels
in serum samples did not differ significantly between the two groups. These results show that petrol station workers are
exposed to these toxic metals. For this reason, it may be recommended that petrol station workers should undergo regular
biomonitoring and healthcare screening.
