EPA researchers have developed tools to model lead levels in human tissues resulting from lead exposure and have worked to reduce uncertainty in human health risk assessments for adults and children exposed to lead. The All Ages Lead Model (AALM) addresses both goals.

Impact/Purpose:
EPA researchers are developing tools to model lead levels in human tissues resulting from lead exposure and are also working to reduce uncertainty in human health risk assessments for adults and children exposed to lead. The All Ages Lead Model (AALM) addresses both goals. The All Ages Lead Model (AALM) predicts lead concentration in body tissues and organs of hypothetical individuals, based on a simulated lifetime of lead exposure. The purpose of the model is to provide risk assessors and researchers with a tool for rapidly evaluating the impact of possible sources of lead in a specific human setting where there is a concern for potential or real human exposure to lead.
Description:
EPA researchers developed the All Ages Lead Model (AALM) to evaluate the impact of lead exposures on lead levels in humans. It rapidly estimates the effect of exposures on lead concentrations in tissues of children and adults; can assess exposures of a day or more, as well as chronic exposures; and can be applied to specific individuals or to groups of similarly exposed individuals.
The AALM is an outgrowth of the Integrated Exposure Uptake Biokinetic Model for Lead in Children (IEUBK). IEUBK assesses changes in blood lead in groups of children up to 7 years of age, over periods of a month or more. The IEUBK is not intended to predict blood lead in a specific individual. The IEUBK is widely accepted as a tool for implementing the site-specific risk assessment process. The AALM expands that modeling capacity with the goal of reducing uncertainty in lead exposure assessments for adults and children.
