Breathing rate

Data

General data on breathing rates by age and gender are available from the EPA [1985, 1989a] and the ICRP [1975]. Values in Table B-1 are taken primarily from the ICRP [1975] with variances estimated by McKone and Daniels [1991]. The working breathing rate is for 8 hours of work and, when combined with 8 hours of breathing at the active rate and 8 hours at the resting rate, gives a daily equivalent intake of 30 m3 for an adult [EPA, 1989b]. Layton [1992] has derived breathing rates that are consistent with the quantities of oxygen needed to metabolize reported dietary intakes of fats, carbohydrates, and proteins. He has shown that the values in Table B-1 could be high by a factor of from 20% to 30%, but this is within the CV reported here.[ttp://www.lbl.gov/ehs/esg/tritium/tritium/TritAppB.html]
