| Abstract |
The U.S. Environmental Protection Agency's (EPA's) National Center for Environmental Assessment (NCEA) publishes the Exposure Factors Handbook and the Child-Specific Exposure Factors Handbook to provide risk assessors with data on various factors that can impact an individual's exposure to environmental contaminants. Both of these handbooks included estimates of ventilation rate--the volume of air that is inhaled by an individual in a specified time period. Previous approach to calculate the estimates of ventilation rate is limited by its dependence on a 'ventilatory equivalent' which, in turn, relies on a person's fitness level. In this document, U.S. EPA presents a revised approach in which the estimates of ventilation rate is calculated directly from an individual's oxygen consumption rate. U.S. EPA then applies this method to data provided from more recent sources: the 1999-2002 National Health and Nutrition Examination Survey (NHANES) and U.S. EPA's Consolidated Human Activity Database (CHAD). |
