Can the IEUBK model be used to develop a site-specific fish advisory?
Yes, in evaluating the fish consumption limits for a specific site, the IEUBK model may be used. The dietary lead input window of the IEUBK model has an option to use alternate dietary lead intake. The alternate dietary intake menu includes ingestion of game animals from hunting, fish from fishing, and home-grown fruits and vegetables. The IEUBK model uses the total lead uptake calculated from the estimated intakes of lead in all media (soil, dust, air, water, and diet) to predict mean blood lead concentration for children (84 months or younger). The IEUBK model assumes the substitution of fish for other meat dishes, so an estimate of fish meals as a proportion of total meat meals is required for the exposure calculation. In estimating lead exposure to children from recreational fishing, appropriate inputs for percent of food class would be 10% for recreational fishing or as much as 50% for high-end case. The average concentration of lead in fish as consumed (either filets or whole fis
