Abstract
The NIOSH analytical method S342 for determining organo-(alkyl)- mercury in air is described. Samples are adsorbed on Carbosieve-B, subjected to thermal decomposition, and analyzed by flameless atomic absorption spectrophotometry. The working range of the method is ceiling and time weighted average analyses, respectively, and the corresponding coefficients of variance are 0.1 and 0.07. The limit of detection for both types of test is 0.001 microgram. Analytical apparatus, reagents and procedures are described and calculations are provided for determining sample concentrations. Data on recovery, stability and breakthrough rates is included.
