Does the Adult Lead Methodology calculate a value for a commercial worker or an industrial worker?
The adult lead methodology does not distinguish between commercial and industrial workers; rather, it is applicable to non-residential exposure scenarios. According to EPA’s guidance on the adult lead methodology, a soil ingestion rate of 50 mg/day is recommended as a plausible central tendency value for non-contact-intensive activities (U.S. EPA, 1997). Either commercial or industrial workers may work primarily indoors, so that exposure to soil occurs primarily via indoor dust. Workers’ limited and occasional contact with outdoor soils (e.g., picnicking, walking to parking lots, standing on a loading dock) should be adequately accounted for via the 50 mg/day incidental soil ingestion. If an individual is performing a contact-intensive activity with soil, then a soil ingestion rate greater than 50 mg/day would be expected. At sites where lead materials have been historically used, exposure scenarios would have to be evaluated individually to determine the indoor and outdoor activities
