Toenail Metal Concentration as Biomarker of Heavy Metal Exposure among Welders

Abstract

Abstract-This study examined the concentration of heavy metal accumulated in the toenail of welders and compared to the concentration of airborne heavy metal exposure in the breathing zone of the welders. Ten selected welders with adequate toenail growth were asked to clip all ten toenails for analysis. The heavy metal concentration in the welder's breathing zone was collected by using mixed cellulose ester filters by using low flow rate air sampling pump. Both toenails and airborne sample filters were analyzed for thirteen elements (Be, Al, Cr, Mn, Fe, Co, Ni, Cu, As, Mo, Ag, Cd and Pb) by using inductively

Development of Neurobehavioral Deterioration Risk Prediction Model for Welder: A Proposed Study

“…al., the mean personal sampling heavy metal concentration and toenail accumulation concentration shows a significant relatable. Hence, the toenail accumulation was a reliable biomarker for continuous heavy metal exposure among welders [8]. A biomarker of acquaintance is any quantifiable natural parameter that shows ranks of acquaintance to a given lethal element, regardless whether it is a prompted protein, enzyme, metabolite, or the lethal substance itself [9].…”
