摘要：The current study was conducted to quantify zinc in nail samples of iron welders from different areas of Lahore,Pakistan. This study intended to assess nutritional deficiencies of zinc in welders. As nails serve a beneficial biomarker of concentrations of trace elements,hence in the present study the nails of welders were used for monitoring. The total number of nail samples collected from workers of iron welding shops,were 40. In a standardized washing procedure the nail samples were scrapped and cleaned of dust particles with nonionic detergent (Triton X-100) and then nail samples were digested afterwards in acid mixture. The concentration of zinc was evaluated by atomic absorption spectrophotometer. The results revealed that concentration of zinc in nail samples ranged 0.297 – 1.718 mg/kg and averaged at 0.88±0.39 mg/kg which is below the ideal zinc levels in nail samples. Correlation of zinc (mg/kg) was significant with age (0.214< 0.5),weight (0.320< 0.5) and Body Mass Index (0.268< 0.5) of the welders,while a weak correlation of zinc (mg/kg) was found with height (0.042< 0.5) of the welders..
