Abstract

Introduction: Lead is an oxidation reduction inactive metal however it interacts with a group of essential elements such as copper, zinc, selenium and chrome and iron. Accordingly current study aims to evaluate the effect of occupational Lead exposure on zinc and chromium level among factory workers. Materials and Methods: A cross-sectional study included 41 Lead exposure workers and 40 non exposure subjects as control group. Serum chromium and zinc were measured using Atomic Absorption spectroscopy. Results: Independent t-test analysis showed, there was insignificant difference in zinc and chromium concentration of Lead exposure subject in comparison with non exposure (p-value= 0.576 and 0.167) respectively. Person’s correlation analysis showed no correlation observed between zinc and study variables (age and duration), also chromium revealed no correlation with study variables. Conclusion: The study concludes that, occupational Lead exposure have no effect on chromium and zinc level.
