Abstract
A commercial rhodizonate test kit was evaluated for use in the detection of lead (7439921) in airborne particulate samples at work sites. Particulate samples were collected on cellulose-ester filter cassettes at abrasive blasting and lead paint removal sites in Ohio. The spot test was applied to 371 filters. The filters were then analyzed by graphite furnace atomic absorption spectrophotometry. For lead amounts below 1.3 microgram/filter there were no positive test readings, while for lead amounts above 8.1 micrograms/filter, there were no negative readings. The authors conclude that the spot test may be useful for the on site screening of lead in workplace air. By adjustment of flow rate, collection time, and other sampling parameters, the lead test kit may be useful for the assessment of lead exposures on the job.
