Some errors in the determination of metal concentrations in the atmosphere using spectral analysis

A simulation study of metal concentrations in atmospheric aerosols and precipitation is described. A radioactive tracer technique involving losses of Na-22, Fe-59, and Pb-210 during the evaporation of precipitation concentrated in a quartz-crucible sand bath was used. Principal losses are due to deposition on the walls. After three rinsings, iron and sodium fully become part of the concentrate, with 15% of the lead remaining on the walls of the crucible.
