Abstract

Lead (Pb) is heavy metal which is naturally found in the earth's crust or originates from human activities, for example from combustion gas emissions in motorized vehicle engines. Republic of Indonesia Ministry of Health Number 1406 / MENKES / SKI / IX / 2002 concerning the examination of lead levels in human biomarker specimens human measurements of lead levels in the human body can be carried out by blood, urine and hair specimens. The purpose of this study is to determine the levels of lead metal in the urine of active smokers. The results of research on lead levels obtained on accuracy parameters, namely the accuracy test results for the method of wet destruction using HNO3 has an average recovery of 71.8% while using HNO₃ added H₂SO₄ has an average recovery of 46.48%, precision test results are obtained % RSD method of destruction on HNO₃ was 28.80%. If on HNO₃ added 50.58% H₂SO₄, linearity test (r) 0.999, LoD value on HNO₃ 0.76 and on LoD HNO₃ H₂SO₄ added. Based on the results of the study of verification of lead metal using wet digestion in the urine of active smokers not in the range of acceptability conditions it indicates that the method cannot be valid for use in the examination of lead in urine by the method of wet destruction in the active smookers.
