Influence of petroleum product exposure on serum micronutrient concentrations in automobile mechanics

Abstract

Background Aim of the Study: Occupation-related pathological presentations have been recognized in automobile mechanics, several of which are oxidative stress-induced. Altered micronutrient levels can help in predicting the possibility of oxidative stress-related diseases. It is for this reason that micronutrient levels are being assessed in auto mechanics. Materials and Methods: Questionnaire was administered to obtain information on workers' safety assessment, lifestyle choices, and work experience. Estimation of micronutrient levels was carried out on sera of 80 adult males, 40 of whom were auto mechanics and the other 40 constituted the control group. Essential trace elements (Zn, Cu, Se, Mn, Co, Fe, Mo, and Cr) and vitamins (Vitamins A, B6, C, D, and E, thiamine, riboflavin, niacin, and folic acid) were determined using atomic absorption spectrometry and high-performance liquid chromatography, respectively. Student's t-test was utilized to establish a significant difference between test and control groups. P ≤ 0.05 was considered statistically significant. Results: Micronutrients with antioxidant attributes such as Zn, Cu, Mn, Se, Vitamin E, and ascorbic acid were significantly reduced compared with controls. Data obtained from an administered questionnaire showed that there were no conscious efforts or program to ensure the safety of the mechanics. Conclusions: Auto mechanics are prone to altered serum micronutrient levels.
