Table 4 IEUBK predicted increase in blood lead concentration due to alloys mouthing exposure in children

From: Migration protocol to estimate metal exposure from mouthing copper and tin alloy objects

Mouthing exposure daily time Alloy Calculated daily lead intakes (μg) by mouthing exposure and IEUBK net blood lead contribution (μg/dL)* per age group
