A study is presented of multi-element multi-media airborne emissions via analysis of solids, soils, wipes, and glass fiber filters on and around two secondary lead smelters.
Characteristic ratios of lead : antimony : arsenic were found in all of these media along with a correlated presence of cadmium and silver.
The further the medium was from the plant, the less of all of these elements found while the ratio was maintained.
Media downwind had higher concentrations than upwind in other directions.
Conclusive forensic evidence was accumulated as to the origin and route of emission of the elements.
