A method for sampling and analyzing metallic fumes was examined. A condensation technique was selected to generate fumes of lead (7439921), tellurium (13494809), and selenium (7782492) to produce metallic particles ranging in size from 0.01 to several microns. A generation temperature of 895 degrees-C was chosen for lead, 500 degrees for tellurium, and 375 and 400 degrees for selenium. Dissolution studies were run on an atomic absorption spectrophotometer. Lead, lead-oxide (1309600), lead-dioxide (1309600), lead-disulfide (12137745) and a standard reference material of lead in paint were dissolved in nitric-acid/hydrogen- peroxide. Sodium-selenium-tetraoxide, selenium-disulfide (56093459), selenium, selenium-dioxide (7446084), and selenium in steel were dissolved in an aqueous solution. Tellurium was dissolved in a nitric-acid/perchloric-acid and a nitric-acid procedure. Platinum (7440064), ammonium-platinum-chloride, and platinum-dioxide (1314154) were dissolved in an aqueous solution. The uniformity of the lead, selenium, and tellurium aerosol concentrations in the sample collection chamber was excellent. The recovery of the lead, selenium, tellurium, and platinum compounds was greater than 90 percent using the modified procedures. The authors conclude that the method for sampling and analyzing metal fumes is within acceptable limits.
