Whole blood iron and manganese levels in artesant welders control subjects were invstigated. Five (5ml) blood samples were collected via venepuncture from thirty (35) welders and twenty five (25) control subjects after their voluntary consent. Samples were digested using standard method. Aliquots of digested samples were assessed for Mn and Fe content with Atomic Absorption Spectrophotometer. The data obtained were expressed as the mean ± Standard Deviation. Independent sample t- test was conducted with the means with SPSS Version 22.0. It was observed that both welders and controls subjects the mean ± S.D were 3.37± 1.34 µg/l and 3.34 ± 1.43 µg/l respectively. Means and standard deviations of blood manganese (Mn-B) levels in welders and controls subjects were 3.37 ± 1.34 µg/l and 3.34 ± 1.43 µg/l respectively. Means and standard deviations blood iron (Fe-B) levels for welders and control subjects were 410 ± 104 µg/dl and 166 ± 37 µg/dl respectively. Significant difference at p < 0.001 was observed when means for test and control subjects were compared. There were no correlations between Mn-B and Fe-B levels of welders with duration of exposure and age. This study has revealed that welders in Elekahia Estate, Community and railway off Trans –Amadi Layout of Port Harcourt have normal Mn-B level with non welders while there Fe-B level is exceptionaly high than non welders. Exposure to iron, may cause iron overload (siderosis) and iron accumulation in liver, heart, and kidney leading to hepatomegaly, myocardial siderosis and metabolic acidosis.
