✦ Synopsis

In adults, lead toxicity is most commonly caused by occupation in a lead industry. Whereas lead toxicity has been described in workers who are involved in bridge rehabilitation, as of this date there has been no systematic evaluation published regarding the conditions responsible for lead toxicity in ironworkers. This is a report of a study designed to identify risk factors for elevated blood-lead levels in ironworkers. One hundred fifty members of a 2,400-member local ironworkers union volunteered to have their blood drawn for lead and zinc protoporphyrin analysis and to complete a questionnaire regarding demographics, health, and occupation. The relationships between these variables and blood-lead level were analyzed using student's t-test, chi-square, and logistic regression. Current work on a lead job, rivet busting as the predominant job task, and cigarette smoking were all found to be significantly associated with elevated blood-lead level. Whereas cigarette smoking and current work with lead have been previously identified as risk factors for toxicity, interventions to prevent lead toxicity in ironworkers should also focus on work practices during rivet busting.

## Abstract To evaluate lead exposure in stained glass workers, we measured blood lead levels in 12 professional glass workers, in 5 hobbyists, and in 4 workers' family members. Professional workers lead levels (mean 20.7 μg/dl) were higher than hobbyists' (11.6 μg/dl) (P = 0.02) or family members'
