A method is described to ensure quantitative measurement of dissolved mercury vapor (Hg°) in blood and urine. Room air passed through samples of blood and urine carries with it all the dissolved Hg° but leaves behind all the ionic mercury (Hg ++ ). Oxidation of Hg° to Hg ++ in blood samples is completely inhibited by addition of ethanol (0.5% v/v). To minimize error due to evaporation of Hg°, it is suggested that samples should be stored at 0 °C and Hg° should be determined within 60 min of collection of blood samples and within 10 min of urine samples.
