The following data sets were previously revised in March 2005 to correct urine cadmium for a possible interference from molybdenum oxide. Recently, it was brought to our attention that after the adjustment, urinary cadmium values below the limit of detection (LOD) were not assigned the imputed value of the LOD divided by the square root of 2. Urinary cadmium values (URDUCD) were updated for 276 records in the 1999-2000 file (LAB06HM), and 324 records in the 2001-2002 file (L06HM_B) to the imputed value of 0.0424 ng/ml. The comment codes for urinary cadmium (URDUCDLC) were updated accordingly as well.
