Exposure to lead-based paints is a major threat to the health of painters. This study aimed to evaluate the blood concentration of lead (Pb) in painters of buildings and cars. The present study was a cross-sectional study in which a semi-structured questionnaire was used to collect the socio-demographic information. Lead concentration in blood samples was determined using the atomic absorption spectrometry method. A total of 32 male painters were selected based on inclusion criteria. The mean blood lead level (BLL) in the painters was 8.1 ± 4.93 μg/dL. Pb levels in car and building painters were 9.42 ± 5.5 μg/dL and 6.7 ± 1.85 μg/dL, respectively. Pb concentration in none of the blood samples was more than 30 μg/dL. The prevalence of BLL ≥ 5 μg/dL and BLL ≥ 10 μg/dL was 97% and 19%, respectively. According to the findings, the rate of BLL among car painters was higher than building painters. Considering the presence of Pb in all blood samples, it seems necessary to increase the awareness of painters about the adverse effects of lead exposure even in low concentrations. However, the sample size in this study was small and more investigations are required in this regard.
