Backup Data Report No. 346.
A method for the sampling and analysis of arsenic (7440382) in the air of the workplace environment was tested for NIOSH validation. Samples were collected on a 37 millimeter (mm) 0.8 micron type AA millipore cellulose ester filter 37mm millipore cellulose backup pad pair, treated with sodium-carbonate and glycerol solution and allowed to dry. The filter backup pad pair and sample were acid digested and analyzed by graphite furnace atomic absorption spectrophotometry. The protocol for establishing NIOSH validation of the method was to analyze spiked samples and samples collected from generated test atmospheres, test the breakthrough capacity of the treated cellulose ester filter cellulose backup pad pair, test storage stability of spiked and generated filters, and assess the precision and accuracy of the method. The aerosol generation and sampling system was presented. The total error for sampling and analysis was less than 25 percent at the OSHA standard 95 percent of the time. The authors conclude this method satisfies NIOSH criteria for validation.
