Development and application of a "real time" lead-in-air analyzer in controlling lead exposure at a primary lead smelter.

To assist in locating and quantifying fugitive emissions in a primary lead smelter, a "real time" lead-in-air analyzer has been developed. Dust is collected on paper tape filters and the lead analysed by X-ray fluorescence. The unit has been used successfully to assist in the implementation of an engineering control monitoring program.
